CNC cutting systems typically machine parts automatically according to a pre-programmed machining program (commonly using software like AutoCAD). We compile the machining process route, process parameters, tool movement trajectory, displacement, cutting parameters (spindle speed, feed rate, depth of cut, etc.), and auxiliary functions (tool change, spindle forward/reverse rotation, coolant on/off, etc.) into a machining program sheet according to the instruction codes and program format specified by the CNC cutting system. This program sheet is then recorded on a control medium (such as punched paper tape, magnetic tape, disk, or bubble memory) and input into the CNC device of the CNC machine tool, thus directing the machine tool to machine the part.
This entire process, from analyzing the part drawing to creating the control medium, is called CNC program compilation. The difference between CNC cutting equipment and ordinary manual or semi-automatic cutting equipment lies in the fact that CNC cutting equipment automatically processes parts according to a program, while ordinary manual or semi-automatic cutting equipment requires human operation. By simply changing the program controlling the machine tool's actions, we can achieve the purpose of machining different parts. Therefore, CNC cutting equipment is particularly suitable for processing small batches of complex-shaped parts requiring high precision!
Because CNC cutting equipment processes parts according to a program, the programmer creates the program and inputs it into the CNC system to control the machine tool. The program is input via a control medium. This CNC system-controlled machining allows for timely modifications to the drawings by the draftsman, providing greater flexibility and significantly improving the precision of the workpiece parts compared to semi-automatic cutting equipment!
