There are three methods for CNC machine tool programming: manual programming, automatic programming, and machining center CAD/CAM.
Manual Programming: This involves manually analyzing part drawings, processing techniques, performing numerical calculations, writing program lists, and inputting and verifying the program. It is suitable for point-to-point machining or parts with relatively simple geometry; however, it is very time-consuming and prone to errors when programming complex parts.
Automatic Programming: This involves using a computer or programming machine to complete the part program creation process. It is very convenient for complex parts.
CAD/CAM: This utilizes CAD/CAM software to achieve automatic programming based on modeling and images. The most typical software is MasterCAM, which can program milling operations using two-axis, three-axis, four-axis, and five-axis coordinate systems, as well as turning and wire EDM. Although this type of software has limited functionality, it is simple to learn and relatively inexpensive.
