To successfully cut the metal and do various processes in manufacturing, we need to use CNC programming since they are a most effective way of doing this work. Many hobbyists are using CNC programming to produce woodworking, metals and foam objects. It is possible to quickly fabricate and manufacture parts we need without hassle, because of the CNC.

CNC stands for computer numerical control and is basically the use of a computer to do certain types of operations. This is a process that can be applied to lathe, router, foam cutters and laser machines; it can also be applied to mini versions of these types of machines.

The continuous path positioning and the point to point positioning are the two categories every CNC program will fall into. Depending on the sophistication of the software we are using, we can make computer to execute first and second type of programming. And what this actually means is that it is needed that both processes are understood by the programmer so he can successfully run the machine.

And now I will present you with the explantaion of the categories stated above:

When punching, tapping, boring or drilling is needed, we usually use point to point positioning category in CNC. While machine process is being done, we use that kind of a process to position from one point to another point. To tell it more directly, it will go from one position to another, no matter how many are there, and it will keep working until the complete process is finished.

To use contouring, we need continuous path positioning which is present in case we work with a lathe or a milling machine at the moment. And this is simply another name that is used for the category. To explain this a bit better, a piece will be completed fully by the cutting tool that will go from one point to another in a continuous motion. This means that the operator has to be able to program the machine so that it continues on several axes at a time and simultaneously.

Any individual will be more successful at its work if it understands both processes.

Machining refers to any process that uses a CNC machine. This could be for routing, milling, drilling, or other types of work that is done with metal, wood or other materials. This is a manufacturing process that uses the automatic opportunity from the computer to create shapes or forms that must be precise.

Raw materials are used and they are put into a CNC machine that uses cutting tools to make these shapes. The CNC machining process involves computers that have at least one microprocessor and several units for storage. With CAD or CAM software systems added to CNC the computer can be programmed to produce the precise movements that are able to create the part.

In CNC machining the process is automated which saves the operator time and saves the business money. The operator is able to load the materials, program the machine and then the machine can work without attention when set up properly; the amount of time it is run without attention is also programmed in.

An important aspect of any CNC Machining is for the operator to know the machine well. CNC is an addition to the general aspects of the machine. As an example, if you are doing routing, adding CNC to the process only automates it. However, for the operator, it means that they must understand the machine, how to put in codes or use CAD or CAM and how to operate the machine; they must also understand how basic routing works.

Another area that is important in order to understand Machining is the basic components of the machine. Like anything around the house that you need working you need to have these machines operate at all times which means you really need to know how they operate in order to be able to fix them if something goes wrong. You really want the operator to get the most out of the machine and you really want that operator to know the limitations and capabilities of the machine in order to do this.

As CNC machining becomes a project the operator is in charge defining five areas. They will first think about the project they want to design and plan it out. This is where sitting down and drawing out plans will be a good idea.

The next area is to understand CAD to translate the drawing into the computer and then an understanding of CAM to translate the CAD information into machine language. In the final area the individual must understand the Controlling function in order to make the machine do what is required. When all these areas are fulfilled properly they allow the individual to create the project in the way they saw it in their drawing.

CNC machining was traditionally only done in commercial settings with very large CNC machines. Today, there are mini-CNC machines that allow the process to be done on a smaller scale in a home workshop. Before the smaller business really had a rought time building parts and products on a smaller scale but now this technology has allowed smaller businesses to be able to do this.

CNC machining can produce both simple and complex designs and can be used on a variety of materials including aluminum, foam, wood and other metals.

G Code Programming is one of the most effective ways that people are using today in order to cut metal and do other processes in manufacturing. Many hobbyists are using CNC programming to produce woodworking, metals and foam objects. CNC has created a way for many people to manufacture or fabricate parts quickly and effortlessly.

CNC stands for computer numerical control and is basically the use of a computer to do certain types of operations. This is a process that can be applied to lathe, router, foam cutters and laser machines; it can also be applied to mini versions of these types of machines.

There are basically two types of categories that CNC Programming will fall into point to point positioning or continuous path positioning. If you are using very advanced software programs then your computer may not be able to execute both types but usually a computer can handle executing both types of programs. This means that the operator must understand both processes in order to run the machine.

Here is a simple explanation of these two categories:

Point to point positioning — this category is mostly used when drilling, boring, punching or tapping is needed. This is a process used to position from one point to another when the machine process is being done. The program will work going to as many positions as it needs to in order to get the process finished whether that is from the X to the Y position or not.

Continuous path positioning — this category is generally used when a lathe or milling machine is being used and is used for contouring (contouring is another name for this category). This means that the cutting tool moves in a continuous motion from one point to another until the piece is completed. This means that the operator has to be able to program the machine so that it continues on several axes at a time and simultaneously.

Continuous path positioning also uses a series of processes called interpolation which is the way in which the machine is programmed to go. Interpolation can be helical, parabolic, cubic, circular and more.  The basic function of this interpolation is to keep the programmed information stored and to monitor and direct the axes in how it should go.

Before any of the programming can be done there is a manuscript that is used which is the basic drawing of what is to be made. This must be studied to make sure that the operator understands the intricacies of the drawing so they can translate the information into the computer software they are using.

This means that the operator must be skilled enough to understand how the paper drawing will translate to the computer, and then be able to program this information into the computer so that the machine will perform the cuts or the processes accordingly.

When you think about this process, it is a good idea to think about what you would do if you were producing the work manually because anything you would do manually, you will depend on the machine to do automatically. By understanding G Code Programming the individual will be more successful.

The CNC Plasma Cutter process has been in existence for over 50 years and was created during World War II. At that time the government needed a welding process that would weld together aircraft parts in a better way than what they were using. This process used inert gas that acted as a barrier to protect an electric arc that stopped oxidation from forming on the weld.

As this process was improved over time, people experimented with the openings in the arc to see how they could create the best way for the process to be done. It was also found that if the opening where the inert gas passed through was restricted it would make a hotter flame. If you look at it a different way, you can make the opening smaller and this in turn would cause the flow to speed up.

The plasma-arc cutting process which is what came out of all of these experiements, became used in the commercial industry in the early 1960s. However, it was a very expensive process for many businesses to take on.

Today, the process has improved dramatically and there are even CNC Plasma Cutting that are portable; some models even have air compressors build in for a fuller portability. Many are smaller and are able to cut sheet metal as their primary work but others can output a lot more in voltage and in work. Also as the CNC plasma cutter was created the process could be totally automated; all an operator has to do is key in how they want the plasma cutter to cut and it does the cut perfectly every time.

CNC plasma cutters come in a variety of sizes but they all basically work the same way. What happens during this process is that you can get gas that is send through a channel where it is pressurized. The gas could be argon, oxygen or nitrogen that is sent through this channel. Inside the channel is an electrode that is negatively charged.  When power is applied to the electrode and the tip of the plasma cutter is touch to the metal, it creates a full circuit.

At this point this circuit makes a high powered spark that goes through the channel; the gas is heated to a very high heat called the fourth state of matter. You will get metal that turns into molten slag when you apply a direct stream of plasma to the metal. What this means is that you have a very high heat and a very fast moving beam of light that hits the metal.

The plasma is what makes the electrical current and this power supply keeps working until the circuit between the electrode and the power supply is broken. Also the cutter nozzle has channels in it so that it can continue to create a consistent flow of shielding gas. This also allows the plasma beam to stay consistent on the metal to be melted.

Some CNC Plasma Cutter have robotic arms that do the work. The point to having this in the CNC mode is that the process is totally automated and it will continue to work to cut with precision as long as the information is programmed correctly into the computer.
