CNC 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 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. You are going to always want someone working with the machine who knows how to put it all together so if something breaks they know how to fix the machine. 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.
Eventually in a CNC Machining project you will have a few different areas that come up for the operator and really its about 5 areas that he will need to define. They will first think about the project they want to design and plan it out. It will be worth your time to sit down and really draw out some plans in this instance.
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.
