Do you ever feel like you know just enough about CNC to be dangerous? Let’s see if we can fill in some of the gaps with the latest info from CNC experts.

Are you good with computers and looking for a job? Well then, consider being a CNC machine operator. It’s usually easy, full-time and the name isn’t intimidating, right?

If you think that being a Computer Numerical Control (CNC) machine operator may be a bit out of your reach, think again. You don’t have to be a math wizard or a programming genius to get that position. But don’t jump in just yet! There are a few things that you have to know (and consider! ) before applying for the job.

The first thing that you have to understand is the abbreviation CNC. According to an online encyclopedia, CNC stands for Computer Numerical Control, and refers specifically to a computer “controller” that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. CNC does numerically directed interpolation of a cutting tool in the work envelope of a machine. The operating parameters of the CNC can be altered via a software load program.

THE PROS

The good thing about being in this job is that the workload is actually light. Operators even complain of boredom because the cycles of CNC machines are all automated. All they have to do is initiate the sequence, sit back, watch for malfunctions, adjust the performance of each machine, and turn them off. If your boss is kind enough to let you use an MP3 player while working, then you sure are lucky.

Another good thing about this job is that job openings for this position will always rise. Technology is moving forward. CNC machining will certainly lead the demand because in CNC, a group of machines can be controlled at the same time. That is exactly what big-time companies want, right? To reduced manual overseeing and just leave it to the machines.

The information about CNC presented here will do one of two things: either it will reinforce what you know about CNC or it will teach you something new. Both are good outcomes.

Advantage in this job arena is easy too. Statistics show that you will need only a high school diploma and (more importantly) an experience in CNC operations to gain an edge.

THE CONS

The thing is, when you’re in this line of work, it is repetitive. One gets bored after doing the same mechanical thing over and over again. As time withers, you will reach a point where you will breathlessly wait for the next paycheck and not actually care about the job. It’s emotionally exhausting. Furthermore, programming and operating these machines can be tedious. So, add that up to boredom and you get disproductivity.

Another thing that you should think about is the work environment. You’re going to be working in a factory. And factories are located away from town. If you’re not comfortable with being away from the hustle and bustle of the city, this might not be for you.

It can get pretty dangerous. Reports show that although most CNC operators work in a well-lit and smoothly ventilated environment, the high-power machinery poses dangers for them in the form of flying particles of metal and plastic. Also, though most modern machines produce less noise, ear plugs are still recommended by experts.

Lastly, this may not sound like a biggie, but most CNC operators are on their feet all day. They can only sit when the programs are being loaded into the computer. It’s pretty comforting that they receive salaries waaaay bigger than those salesladies.

The best course of action to take sometimes isn’t clear until you’ve listed and considered your alternatives. The following paragraphs should help clue you in to what the experts think is significant.

The advent of Computers lessened the need for human intervention in almost all aspects of our daily lives. This is especially true in the industrial sector now that production is virtually automated.

Precision and accuracy

Computer numerical control has been able to help companies in terms of precision. With the need for more complex designs and more complex operations, human workers could not cope with the required precision that comes with advancement. CNC machines were able to alter that idea by allowing increased precision and lesser error ratios with regards to production.

Another important improvement that CNC has brought with it is the increased accuracy. The dimensions of components have to be very accurate. And since an increase in production speed also increases the error ratio, CNC has helped lower that ratio by the increased level of automation and the error detection capabilities that computers have.

Speed

In the industrial sector, speed is of the essence. With CNC technology, the normal production capacity has been increased exponentially. This means that effective and accurate production methods have been developed. Mass production requires more scrutiny for errors and mistakes. However, anomalies can also be corrected. The programming structures of CNC machines can be altered in a fast way. This means that mistakes do not have as serious an impact as they had before CNC was improved to this level.

If your CNC facts are out-of-date, how will that affect your actions and decisions? Make certain you don’t let important CNC information slip by you.

Machine versatility

CNC machines have become very versatile with regards to the tools that they use. They can easily be assigned to different tasks and thus can be very productive. Tools and networks can be switched without compromising the speed of the production. Aside from this, one machine can do more than one task at a time. This exceeds the normal human capacities as it allows more tasks to be accomplished at a faster rate than before.

Furthermore, when one machine tool breaks down, it can easily be pulled off the grid to prevent it from affecting the whole production cycle. It can then be replaced or repaired on the spot.

Lesser human intervention

Since component production is a very tedious and repetitive operation, human error skyrockets as time passes. This is due to fatigue and other factors. Furthermore, the ability of a person degrades due to psychological and emotional factors. This means that if a person works on the same job for a certain amount of time, the person may eventually get bored or tired or both. This increases the possibility for the human to commit an error and thus causes a drop in the efficiency rating of that person. A machine, however, does not get tired or bored. A machine does not have any concern at all.

Therefore, a machine increases efficiency ratings by speeding up production and eliminating or reducing factors that threaten efficiency. In this case, one must simply program the machine to start a cycle. Furthermore, humans have to be fed, paid, and rested. Machines only have to be rested when failures occur to often and they do not need to be paid or fed.

This brings us to the conclusion that companies will be able to save a lot in the long run. While investing in CNC machines is not cheap, maintenance will only cost a fraction of what will be paid to manual laborers.

Have you ever asked yourself how machines in a factory know exactly when to stop making the parts they’re supposed to make? Well, this is all because of Computer Numerical Control (CNC). But to understand CNC, you have to know what Numerical Control (NC) is.

HISTORY

NC machines were first introduced after the 2nd world war as mass production became the trend. These machines were given a set of instructions in punched cards. However, these machines were hard-wired and their parameters were difficult to change.

These NC machines still required a great deal of human intervention. To illustrate this point, try to take a look at a drill press. A lot of actions have to be taken in order to manufacture a product. The process is actually so complicated that a person has to do something almost every step of the production process. This created an avenue for errors to take place as the likelihood of fatigue increased with the quantity growth.

CNC then came into the picture when computers were introduced. Punched cards were replaced by floppy disks, cables, and other software transfer media. This made it easier to manage and edit data.

Production and manufacturing were revolutionized by the increased automation of CNC machines. These machines allowed a degree of added control over the quality and consistency of the components that were manufactured without any additional strain on the operators. This reduced the frequency of errors and allowed the operators time to perform additional tasks. Furthermore, this automation allowed a greater degree of flexibility in the way components are held in the manufacturing process.

Most of this information comes straight from the CNC pros. Careful reading to the end virtually guarantees that you’ll know what they know.

With the advent of Computer Aided Manufacturing (CAM), even programming CNC machines is a snap. These programs actually take the bulk of the programming process to make the operation less tedious. However, to be an effective programmer of CNC machines, you have to know what the machine you’re working on will be doing. That is why machinists are often the best people for the job.

The ease that the machines provide is hinged heavily on the quality of the machine. Low-cost CNC machines oftentimes have many functions that have to be manually activated. High-cost machines, however, are almost fully automated. The operator only has to load or unload workpieces. Once the cycle has been initiated, the operator just has to sit back and watch for any malfunctions. The stress on the operator is so low that some even complain of boredom in the middle of a cycle.

CODING

The programming language that CNC uses is called a G-Code. These codes actually position the parts and do the work. To be able to have a machine work properly, you have to input the correct variables such as axes, reference points, the machine accessories, and whatnot. Every machine has a different set of variables so you have to be careful to take note of the differences.

Aside from the G-Code, logical commands or parametric programming can be used to make the process more time-efficient. This type of programming language shortens lengthy programs with incremental passes. A loop can also be programmed thereby removing the need for coding repetitions.

Because of these features, parametric programming is more efficient than CAM. It allows users to directly and efficiently make performance adjustments. It also allows extensions to the functionality of the machine it is running on.

And that makes CNC.

The following paragraphs summarize the work of CNC experts who are completely familiar with all the aspects of CNC. Heed their advice to avoid any CNC surprises.

A CNC machine cannot function without a program. And a program cannot make its way to the machine without an effective data transfer system. So, what are the methods of data transfer and how effective are they in conveying data from one point to the next?

Punched tape

The first data transfer method is the punched tape. It consists of a long strip of paper with holes punched in it to store data. The holes represent a set of data that tells the machine how to move and what to do.

This method has proven to be very versatile and very useful. It has proven to withstand the test of time as numerous magnetic storage devices have deteriorated over time even to the extent of being unreadable while punched tape has been shown to be fine decades and perhaps even centuries later. Repair is also not a problem as specially designed splices can put two end together virtually unchanged. Furthermore, punched tape can be visually decoded should the need arise. This means that human accessibility is also not a problem.

Floppy Disk

While punched tape is quite a long roll of paper, a floppy disk is a small magnetic storage device that is more space efficient than punched tape. It can also be used to store simple programs.

Floppy disks virtually revolutionized the way data could be stored and transferred from one point to another. It allowed users to store and transfer data faster than punched tape allowed. Furthermore, the data within a floppy could be easily edited at any point as long as you have the proper program to read it. However, this method has proven to be quite problematic in the long run as floppies have a tendency to degrade alarmingly fast. A floppy could be unreadable after only 3 years.

RS232

Once you begin to move beyond basic background information, you begin to realize that there’s more to CNC than you may have first thought.

This method is actually a set of standards for serial binary signals that connects between computers, terminals, and modems. This is a fast and efficient way to transfer data.

This cable connects a CNC machine to a computer that has floppy disk support thus eliminating the need for punched tape. This allows the operator to input data remotely and even while accomplishing other tasks. However, it need to be used in conjunction with an effective data storage device so as to have backups in case of emergencies.

Networks

Networks are a set of computers that are linked together to make data sharing easier. In an industrial scenario, networks allow a number of different users to individually create a program for the machine to run on.

This method allows multiple users to access and transfer data remotely. This allows for a faster and more efficient check-and-balance system for the programmer and the data verifier. Furthermore, different parts of the program can be completed by different programmers and then compiled by one user. This makes program creation a fast and easy process.

Manual Data Input (MDI)

MDI allows users to input commands directly into the CNC machine’s memory. This may seem to be an effective way of telling the machine what to do but it actually has a lot of drawbacks to it.

Despite it being the fastest way of telling the machine what to do, it is also a very risky and tedious operation as it requires the use of the machine’s terminal. Furthermore, the construction of a program is not as fast as opposed to the network method. It only allows one user to access the machine thus making it a long and drawn-out process.

Another disadvantage that comes with MDI is that it limits the operator to only one task at a time. However, MDI allows the most control over the machine compared to other methods.

That’s how things stand right now. Keep in mind that any subject can change over time, so be sure you keep up with the latest news.

In today’s world, it seems that almost any topic is open for debate. While I was gathering facts for this article, I was quite surprised to find some of the issues I thought were settled are actually still being openly discussed.

Since the dawn of the CNC (Computer Numerical Control) machines introduction in the machining sector, they have been praised for being accurate, fast, consistent and flexible. Although CNC machines are not totally independent, a lot of major industries depend on these wonder machines. Common CNC-dependent industries include the metal industry and the woodworking industry. However, these industries, when small-time, can be operated by hands.

In this article, you will learn about the industries which are CNC dependent not because they have grown big in time but because they have to. It can be also that they are CNC dependent because their industries demand a low level of tolerance and a high level of sophistication. There are no “small-time” members of this industry. Let’s start discussing.

THE AEROSPACE INDUSTRY

First off, this is already a very sophisticated industry. An engineering degree (solely) will not get you anywhere in the Aerospace industry. Not even within striking range. This industry demands so high from their members so machine shops that belong to this industry trust only the best of the best of CNC machining. In fact, sources say that the term “Precision Machining” has been coined from this industry.

In the materials they use, the aerospace industry already demands a lot. CNC machines which are used here are mostly capable of handling Inconel, Titanium, Magnesium, Stainless Steel and so much more. From parts of the landing gear, to shuttle seats, to housings, and even oxygen generation, CNC machines play a big part in their manufacturing.

It’s not just that. Every CNC machine used in this industry also has to be approved AND RATED by the Federal Aviation Administration (FAA) to be safe and to be surely capable of “Precision Machining”. A NASA experience is highly praised too.

THE MEDICAL INDUSTRY

Knowledge can give you a real advantage. To make sure you’re fully informed about CNC, keep reading.

If the Aerospace Industry demanded precision above all, the Medical Industry demands sterility as much as precision. That’s something that you may have known since you got your first vaccine. Most CNC machines which work for this industry are multi-spindle and contain multi-turret lathes.

These special features allow the company to turn out components for hospital equipment, pulse meters, blood purification systems and mother medical devices. They are also useful in the mass production of disposable items and non-embeddable components.

High-torque milling and turning spindles are heavily demanded in this industry to enable users to process all substrates currently used in the medical device and orthopedic implant markets. Moreover, CNC machines recommended in the medical industry are those which can properly handle Titanium, Cobalt Chromium, Nitinol and others.

THE MILITARY INDUSTRY

This industry’s main concern aside from precision is security. In fact, if you try to search online the CNC-manufactured materials or CNC machines used in this industry, no matter how famous their reputation is, the manufacturer cannot display (pictures of) the materials that they have produced for their clients. They can only display products which they are used in.

This industry deals heavily with Inconel, Titanium, Kevlar, Monel and Hastealloy; so most CNC machines recommended in the Military industry must be able to handle those.

Famous CNC standards evaluators in this industry include the Department of Defense (DOD), the Mil Spec (Military Specifications) and other selected military sectors.

The top managers of these industries also demand their CNC machines to be purchased from CNC machine suppliers which adhere to the International Standards Organization (ISO). And because these industries are CNC-dependent, their shops can occupy a vast amount of space. Basically, that makes no room for old school methods and errors.

When you think about CNC, what do you think of first? Which aspects of CNC are important, which are essential, and which ones can you take or leave? You be the judge.

CNC machine tools are praised all over the world because of three major factors: automation, accuracy and versatility. Human (operator) intervention is reduced to minimal levels because CNC machines can run on its own after it is programmed. Also, when the program is perfected, the CNC machine can run the instructions perfectly on its own.

Remember that any CNC machine can also be programmed to do special one-time tasks such as a dry-run, which will help the operator oversee what will happen when s/he leaves the CNC machine to do its tasks alone. Accuracy also goes hand in hand with repeatability. Again, once the program is perfected, the CNC machine can perform that task PERFECTLY even until 7 or 7000 times.

Lastly, versatility also works in the form of “task memory” that these CNC machines have. Once a program has been performed even for just one production run, it can be easily recollected the next time that the company needs the program. This saves time for setting up and loading of different programs.

The CNC sure simplifies the work of thousands of factories and machine shops worldwide. However, no matter how great CNC sounds like, it is something that doesn’t fit in some industries. Like, perhaps, in the cosmetic industry, or in the show-business. Those examples are way too obvious. On the other hand, in these two major mechanical industries, CNC is almost synonymous to “hero”.

THE METAL INDUSTRY

Think of Metal. Metal. Perhaps the easiest metal that you can imagine is that of…a spoon. Now, imagine ANY spoon done with bare hands. After that, imagine a thousand spoons done with bare hands. It’s so tedious you might even consider suicide if you are assigned to such a job.

The metal industry has been operating on CNC for ages. In fact, if you search CNC in the internet, you will instantly find metal companies topping the list. The major CNC centers that you will find in most metal machining processes are “CNC turning centers”, “CNC machining centers”, “CNC grinding centers” and “CNC drill and tap centers”.

It seems like new information is discovered about something every day. And the topic of CNC is no exception. Keep reading to get more fresh news about CNC.

Some of the CNC programs that are connected with the metal industry are milling, drilling, reaming, boring and tapping. Moreover, any metal that has any curved side have experienced some form of knurling, grooving, turning and/or threading.

Fabrication, in manufacturing, refers to processes that are executed on thin plates/sheets. These sheets are cut, punched, and bent to form their finishing shapes. CNC also stars in almost every aspect of metal fabrication.

THE WOODWORKING INDUSTRY

While the most beautiful wood-worked products are most likely hand-made, you cannot deny that a wide array of tools and furniture HAVE to be NOT hand-made to save time and for mass production levels. There’s just too much work and not to many hands. In light with this, CNC has worked wonders for this industry.

Important woodworking processes include cutting, framing, carving and engraving. The most useful woodworking CNC product is the CNC router table. It is capable of carving elaborate 2D and 3D designs. Moreover, it is also capable of material change while repeating the same design. Since contemporary furniture is often a splash of different materials (e.g. Wood, aluminum and/or plastic), any CNC router is capable of reproducing the same design EVEN in different kinds of materials by just altering the router bit.

Although many local, middle-sized enterprise owners are skeptical about using employing CNC in their manufacturing operations, there have been many success stories to sway them to using it anyway. In the Metal and Woodworking industries, CNC has proven itself time and again to be efficient.

It saves time and efforts in production and (more importantly) back-jobs. If you’re venturing to one of these industries, remember that the word “labor” isn’t something social anymore - it’s technological. And start calling CNC your best friend.

This interesting article addresses some of the key issues regarding CNC. A careful reading of this material could make a big difference in how you think about CNC.

In the employment world, the phrase “manual labor” is often associated with jobs which are dirty, psychologically sickening, or worse, both. Small to medium-size manufacturing enterprises are moving towards using the CNC(Computer Numerical Control) in their major manufacturing processes because of its fame in accuracy, flexibility and automation. If you’re one of these entrepreneurs, don’t jump in the bandwagon just yet.

Acquiring a CNC machine is more than just buying additional equipment; it also has a social aspect in it. Here is the low down:

PEOPLE-WISE

First, you have to consider the people who are working in your shop. How many people will be displaced if you buy a CNC machine? Keep in mind that a CNC machine is multi-operational; so it’s possible that a couple of laborers will be erased from the production team. Experts say that the healthy ratio is at least one-sixth (1/6) of your whole labor force.

You will be saving time and effort, yes, and that is the best thing about having a CNC machine. However, you might be worrying about actually terminating people because, to put it bluntly, you won’t need them anymore. A CNC machine, just like any machine, will need an operator. Instructions used by a CNC machine for operational execution are composed of CNC “words/codes” and is in the form of a “sentence”.

Does one of your people ever have experience with a CNC machine before? Can s/he formulate CNC instructions? If the answer to both questions are “yes”, then that’s absolutely good news. However, if you answered “no” to at least one of the questions, then there are more things to evaluate.

Are your people capable of fast-learning? If it pains you to terminate them because they have been good employees in the past, train them on how to use the CNC machine and how to compose instructions for it. There are plenty of free training kits online.

If your CNC facts are out-of-date, how will that affect your actions and decisions? Make certain you don’t let important CNC information slip by you.

COMPANY-WISE

There’s a corporate adage that goes: “Innovate or die”. There’s a lot of truth in that. A purchase of any CNC machine symbolizes a company’s decision to innovate to increase productivity. However, there are a few things that you need to note.

Review your company’s history. How long should you innovate drastically in terms of production? CNC equipment is expensive. It is an investment. In the long run, you may be forced to buy new equipment more often. Consider CNC heavily if you feel that your company innovates faster than other companies in terms of the industry that you belong to. After all, you can easily alter designs and material when you have CNC powered operations.

In most companies, “Innovation” is another word for “saving”. It means saving time, effort and space. In using CNC machines, the first two factors are sure savings while the third is not. People doing the labor and CNC machines often occupy the same amount of space. Do not romanticize a “clearing of clutter” effect when you buy a CNC machine. You will keep up, in terms of production; but CNC equipment also occupies a lot of space. So in that aspect, it’s pretty much the same thing.

Another thing that you have to be reminded of is the level of accuracy that your company needs to produce. Intricate patterns on metal/wood will DEMAND CNC accuracy. So any time that you feel your company is ready for such innovation and accuracy, consider employing CNC in your manufacturing.

At the end of the day, the last aspect that you need to evaluate is you, yourself. As the owner/head manager, you have to KNOW AND UNDERSTAND the CNC machine and the software well. This is the biggest battle that you have to face.

The equation to improvement is simple a really good machine plus a really good operator (you). Do not easily be blinded by the salesmen’s poetry.

When you think about CNC, what do you think of first? Which aspects of CNC are important, which are essential, and which ones can you take or leave? You be the judge.

You might have not heard of the CNC before, or what it does, or how it makes lofty manufacturing operations a lot easier. However, CNC machining is dubbed as one of the most important factors of most production processes. The common tasks CNCs machines usually perform are drilling holes, tool changing, cooling and lubrication of separate factory machines at the same time.

Let’s start with a brief introduction. CNC stands for Computer Numerical Control and it has been around since the early 1970’s. Before it was christened CNC, it was called NC, for Numerical Control. When computers were introduced during 1070’s, the name changed. It has stroked almost all manufacturing forms in almost all stages of production. CNC machines either substitute some existing manufacturing processes or combine work with them.

A CNC program is just any other set of instructions. It’s written like a sentence and the order of operation is chronological. The machine will then execute that set of instructions step-by-step. A special series of CNC words/codes are used to relay what the machine is supposed to do. CNC codes begin with letter addresses (like S for spindle speed, and X, Y & Z for common linear axis motions).

When certain codes are arranged together in a coherent method, this group of CNC codes create a “command” that is like a sentence. A common CNC machine will only be needing around 40-50 words/codes to program different commands. See, it’s not very difficult to learn.

Although CNC sounds very independent and do-it-all, there are a few words that you need to know to fully understand CNC operations.

THE CAM

Those of you not familiar with the latest on CNC now have at least a basic understanding. But there’s more to come.

CAM stands for Computer Aided Manufacturing. It simplifies the programming processes which are new, and added to the CNC program regularly. Of course, the easy applications can be programmed with only the simplest machines around: the pen, paper and calculator. However, more complex programs are vital regularly. It is when composing these programs become much more tricky and (worse) tedious.

The CAM is a program that runs on a computer that aids the CNC programmer with the programming. It also works hand-in-hand with the CAD (Computer Aided Design) design drawing (those designs engineers compose/nurture). With the CAM helping, redefinition of the work-piece configuration is not needed. What the CNC programmer is left to do is just to specify the machine operations to be executed and the CAM system will compose the CNC program automatically. Thanks to CAM, programming tediousness will not be a problem to the CNC programmer again.

THE DNC SYSTEM

DNC stands for Distributive Numerical Control. It is a computer that is connected with one or more CNC machines, forming a network. When a program is manually composed and ready to be loaded to the CNC control, it is being typed right into the control. However, this is like using the CNC machine as a luxurious keyboard.

Moreover, if the CNC program is achieved with the help of CAM, it is already in text form and ready to be loaded to the CNC control. The DNC simply distributes the CNC program to more than one CNC machine. Lately, the newest controls are more advanced in terms of networking capabilities and can be networked with, say, the Ethernet.

If it’s your first time to read and learn about the CNC, it may sound so mighty and ubiquitous. It’s about time you learn they also need help from some programming friends such as the CAM and the DNC. No man is an island; but hey, neither are CNC machines.

So now you know a little bit about CNC. Even if you don’t know everything, you’ve done something worthwhile: you’ve expanded your knowledge.

If you’re seriously interested in knowing about CNC, you need to think beyond the basics. This informative article takes a closer look at things you need to know about CNC.

Computer Numerical Control Machines are sophisticated instruments that only trained CNC operators should operate them. There are certain rules and guidelines to consider if you are planning to use a CNC machine by yourself.

CNC checklist before startup

Before starting up the Computer Numerical Control Machine, there are safety rules that must be considered first. First important aspect before starting up the CNC machine is to ensure your own safety, therefore wearing protective gear, such as eye glasses and short sleeved shirts is an important dress code during CNC operation. You should also be careful whenever you are handling tools and sharp edged work pieces to avoid any accidents. You must also ensure that the cutting tools are fastened in the machine spindle to avoid any movement during the cutting operation.

Actual Startup, Operation and Machine Setup of the CNC

The Computer Numerical Machine startup procedure varies depending with the type of machine being used but usually there is a main power switch or a circuit breaker to turn it on. Some machines also require hydraulics or air pressure before it starts up.

If you find yourself confused by what you’ve read to this point, don’t despair. Everything should be crystal clear by the time you finish.

When the Computer Numerical Machine starts up, the machine usually starts at its Machine Home Position. The Machine Home Position allows the control and the machine to have a preset starting position for all its axes. After startup, the CNC machine must be sent to this position before the work begins. This position will later be changed to an appropriate location whenever you are machining a particular part of a product.

The Tool Length Offset Value or TLO is the distance from the tip of the tool from the spindle in the Home Position. The TLO must be set for each tool in the current job. The TLO can be set using a height gage, fixture location, as well as the reference tool. When these values are determined, they are stored in the Controller to be used during the program operation.

After setting the Tool Length Offset Value it is time to setup a part origin of a CNC machine. Setting up the part origin on a CNC machine is the same as setting up a conventional machine. It usually involves positioning the axes to a point where the plan designates as its origin. There are many ways to locate the position on the reference point, it is by using edge finders, wigglers or magnifying glasses.

After setting up the whole system for the Computer Numerical Control, it is time to Load the program to the machine. Program loading is different for each machine. Some machines have tape readers to input the program into the Computer Numerical Control Machine’s memory. Newer machines have internal or external floppy devices to input the program to the machine. After the program is loaded to the machine, the CNC machine is now ready to use.

There are certain instances when you have to change the tools in the Computer Numerical Control manually during machine operations. When a certain machining operation is complete, the program will move the aces to the tool change position and display the next tool needed. It is now the job of the Machine operator to remove and replace it with the next tool.

Extra Care must be taken whenever you are starting operations with the CNC machine, any mistake taken during the part of the operation may lead to serious injuries from the machine operator.

Manufacturing anything that requires exact measurements requires cutting edge precision and nimbleness from the worker. Most of the time manufacturing these kinds of products requires weeks or months to finish therefore slowing down productivity as well as consistency of the manufacturers.

Computer Numerical Control or more commonly called as CNC’s are the new trend in machine shop manufacturing and practice. Any manufacturing environment owns one or is basically acquainted to this kind of device because of its capability to increase productivity as well as consistency on the products being produced.

Benchmarked from Numerical Control (NC) during the late 50’s, Computer Numerical Control incorporate the functionality of a Programmable Logic Controller (PLC), meaning you could program it to execute different functions depending on the type of manufacturing that the industry needs.

Given this kind of quality what does the Computer Numerical Control do in the practical application concept? CNC can do a variety of things depending on how the machine operator would program the system. The more acquainted the machine operator is to the CNC machine the more complex applications as well as programming can be made. Practical applications of CNC range from drilling, lathes, multi-axis spindles, milling machines, laser cutting machines, and wire electrical discharge machines.

Let’s discuss some of these common applications further. In Metal fabrication, Computer Numerical controlled Lathe’s are used to fabricate metal sheet by shearing, flame or plasma cutting, punching, laser cutting, forming and welding. Most CNC Lathe’s are used for designing modern carbide tooling. The design could be created with the Computer Aided Manufacturing (CAM) process, and when done, the CNC could start creating the product automatically with little supervision from the machine operator.

I trust that what you’ve read so far has been informative. The following section should go a long way toward clearing up any uncertainty that may remain.

Electrical discharge machining (EDM) is the process of removing metal with the use of electrical sparks to take away the metal. These Electrical Discharge Machine has two types, the vertical EDM and wire EDM. Vertical EDM uses an electrode that is the shape of the cavity to be machined into a work piece. Wire EDM is used to create punch and die combinations in the fabrication industry. Computer Numerical Control EDM’s are not usually known because it is mostly incorporated to other CNC process.

Drilling is the most common machine process. Computer Numerical Controlled Drilling is used to create precise right circular cylinders over a certain material, the CNC could be programmed to create holes on different standards, most of the time this is the gaps between these holes. Drilling is commonly used in wood working manufacturing process in which other process is also involved such as milling, turning and grinding.

Several tools for creating holes with CNC’s involve varied hole sizes as well as drill press for creating different depths on its holes. CNC drills are equipped depending on the type of hole that the machine operator is drilling.

Applications stated above are just a few examples on what the Computer Numerical Control could execute. Depending on how you want it to perform, more complex designs can be made and a lot of things can be made in a shorter period of time, therefore the key concept for the proper use of CNC’s is that the machine operator must know what he or she wants to do.

This makes the CNC an indispensable tool for the Manufacturing Industry nowadays.

It never hurts to be well-informed with the latest on CNC. Compare what you’ve learned here to future articles so that you can stay alert to changes in the area of CNC.
