CNC machining: system performance of CNC

The performance analysis of numerical control (CNC) system includes the type of control system, the definition of coordinate system, the definition of spindle speed range, feed speed, the identification and numbering method of tool, the requirements for arc interpolation, the linkage mode of axis, the corner control method, the mode of tool movement (rapid movement, linear movement and arc movement), etc;

It also includes the format of the CNC program, the syntax structure of the CNC program, the common CNC programming instructions and their use rules. The CNC machine tool manufacturer introduces that the control system is the core part of the CNC machine tool. When planning the CNC program, the programmer must have a clear understanding of the standard instructions of the control system. Only in this way can the unique functions and scientific programming methods of the CNC system be used, such as machining cycle, subprogram, macro instruction and other functions.

It is suggested that programmers can have a good understanding of CNC machine tools and CNC systems, which is very useful and innovative for writing high-level and high-quality CNC programs. The effective use of CNC system functions and the quality of CNC programs reflect the programmers' understanding of CNC machine tools and CNC system functions.

An important reason is that the programmer's personal experience and professional knowledge are increased during the process of part CNC program planning, including the subsequent CNC programming.
