Usually, CNC cutting systems automatically process the processed parts according to pre programmed machining programs (commonly used drawing software AOTOCAD). We compile the machining process route, process parameters, tool motion trajectory, displacement, cutting parameters (spindle rotation, feed rate, back feed, etc.) and auxiliary functions (tool change, spindle forward rotation, reverse rotation, cutting fluid on/off, etc.) of the parts into a machining program sheet according to the instruction code and program format specified by the CNC cutting system, Record the content of this program sheet on the control medium (such as perforated paper tape, magnetic tape, magnetic disk, magnetic bubble memory), and then input it into the CNC device of the CNC machine tool to command the machine tool to process parts.

The entire process from analyzing part drawings to making control media is called the programming of CNC programs. The difference between CNC cutting equipment and ordinary manual and semi-automatic cutting equipment in processing parts is that CNC cutting equipment automatically processes parts according to the program, while ordinary manual and semi-automatic cutting equipment needs to be operated by humans. We can achieve the purpose of processing different parts by changing the program that controls the machine tool action. Therefore, CNC cutting equipment is particularly suitable for processing small batches of parts with complex shapes and high precision requirements!
