About CNC Machining

Aug. 08, 2019

CNC Machining refers to machining with CNC machining tools. The CNC index control machine is programmed by the CNC machining language, usually G code. The CNC machining G code language tells the CNC machine tool which Cartesian position coordinates to use, and controls the tool feed speed and spindle speed, as well as tool converters, coolants and other functions. CNC machining has great advantages over manual machining. For example, CNC machining produces parts that are very precise and repeatable. CNC machining can produce parts with complex shapes that cannot be completed by manual machining. CNC machining technology is now widely promoted. Most machining shops have CNC machining capabilities. The most common CNC machining methods in typical machining shops are CNC milling, CNC and CNC EDM wire cutting (EDM cutting).

The tool for CNC milling is called CNC milling machine or CNC Lathe Machining center. The lathe for CNC turning is called the CNC turning center. CNC machining G code can be manually programmed, but usually the machining shop uses CAM (Computer Aided Manufacturing) software to automatically read CAD (Computer Aided Design) files and generate G code programs to control CNC machine tools.


In the machining of CNC Machining Equipment Parts, the determination of the processing route generally follows the following principles:


1. Ensure the accuracy and surface roughness of the work piece being machined.

2. The processing route is the shortest, the idle travel time is reduced, and the processing efficiency is improved.

3. Simplify the workload of numerical calculations and simplify the processing procedure.

4. For some reusable programs, subroutines should be used.
