Numerical control machining refers to the processing carried out using numerical control machining tools. CNC index controlled machine tools are programmed and controlled using CNC machining language, usually in G-code. The CNC machining code language tells the CNC machine tool which Cartesian position coordinates to use for the machining tool, and controls the feed rate and spindle speed of the tool, as well as functions such as coolant and tool converter.

The CNC machining code language tells the CNC machine tool which Cartesian position coordinates to use for the machining tool, and controls the feed rate and spindle speed of the tool, as well as functions such as coolant and tool converter. Numerical control machining has significant advantages over manual machining, such as producing parts that are highly reproducible; Numerical control machining can produce parts with complex shapes that cannot be completed by manual machining. CNC machining technology has been widely promoted, and most machining workshops have CNC machining capabilities. Typical CNC machining methods commonly used in machining workshops include turning, milling, and CNC EDM wire cutting.
The tool used for CNC milling is called a CNC milling machine or CNC machining center. The lathe used for CNC turning is called a CNC lathe center. The G-code for CNC machining can be manually programmed, but usually the machining workshop uses CAM (Computer Aided Manufacturing) software to automatically read CAD (Computer Aided Design) files and generate G-code programs to control the CNC machine tool.
In CNC lathe machining, the determination of the machining route generally follows the following principles.
① It should be able to ensure the accuracy and surface roughness of the processed workpiece.
② Try to simplify the workload of numerical calculations and simplify the machining program as much as possible.
③ Shorten the processing route, reduce idle travel time, and improve processing efficiency.
④ For some reusable programs, subroutines should be used.
