CNC (Computer Numerical Control) Machining is mainly used in manufacturing, where a computer is used to control the machine tool during the process.
When using CNC machine, a CAD design file is first created and imported into the CNC machine. A code commonly known as G-code is then generated to control the machining tool, including feed rate, location, coordination and speed.
Testing is also required before production to ensure that the code generated for CNC is identical to the original file.
After all these steps are complete, production begin and the material is loaded to CNC. The machining process is roughly the same regardless of the number of workpiece.
In some cases, to better control heat and debris, operators spray cutting fluid on machining tools during the process. This ensure that the tools will not be damaged by overheating and also help better control of the tool.
There are many advantages to using CNC machining, it has extremely high accuracy that can machine complex shapes, and the process can be repeated in exactly the same way. These are all difficult to do manually. Therefore, CNC machining has a wide range of application and can easily convert any 2D or 3D project into a high-quality machined result.
