What is machining?
Machining is the abbreviation of machining, which refers to the process of removing materials by mechanical precision machining. Mechanical processing (machining) mainly includes manual processing and numerical control processing
1. Manual processing refers to the method of processing various materials by manual operation of milling machine, lathe, drilling machine and sawing machine by mechanical workers. Manual processing is suitable for small batch and simple parts production.
2. CNC machining (CNC) refers to the use of numerical control equipment by mechanical workers. These CNC equipment include machining center, turning and milling center, WEDM equipment, thread cutting machine, etc. The vast majority of machining workshops use CNC technology. By programming, the position coordinates (x, y, z) of the workpiece in Cartesian coordinate system are converted into program language. The CNC controller of CNC machine tool controls the axis of CNC machine tool by recognizing and interpreting the program language, and automatically removes materials according to the requirements, so as to obtain the finishing workpiece. CNC machining is a continuous way to process workpieces, which is suitable for large quantities of complex shape parts.
CAD / CAM (computer aided design and computer aided manufacturing) system can be used in machining workshop to program NC machine tools automatically. The geometric shape of parts is automatically converted from CAD system to cam system, and the mechanical workers choose various processing methods on the virtual display screen. When a certain machining method is selected by mechanical workers, the CAD / CAM system can automatically output CNC code, usually G code, and input the code into the controller of CNC machine tool for actual machining operation.
