Introduction to machining process
May 19 , 2023
Machining is the abbreviation of mechanical processing, which refers to the processing technology of removing materials through precise mechanical processing. Machining mainly includes two categories: manual processing and numerical control processing.

Manual processing

Refers to the manual operation of mechanical equipment such as milling machines, lathes, drilling machines, and sawing machines to achieve various

The method by which the material is processed. Manual processing is suitable for small batch and simple part production.

CNC machining

(CNC) refers to the use of numerical control equipment for processing, including machining centers, numerical control lathes, electric sparks, cutting equipment, etc. CNC machining processes workpieces in a continuous manner, which is suitable for parts with large quantities, complex shapes and high precision.

At present, the vast majority of machining workshops use CNC machining technology. Through programming, the position coordinates (X, Y, Z) of the workpiece in the Cartesian coordinate system are converted into a program language. The CNC controller of the CNC machine tool controls the axes and tools of the CNC machine tool by recognizing and interpreting the program language, and automatically cuts according to the requirements. material, so as to obtain the finished workpiece.

Furthermore, CAM (Computer Aided Manufacturing) system can be used to automatically program CNC machine tools. The model of the part is automatically converted from the CAD system to the CAM system, and the CAM system can automatically output the CNC code (usually refers to the G code) and input the code into the controller of the CNC machine tool for actual processing operations, such as commonly used 3D software After the modeling is completed, automatic programming is performed through Mastercam software.
