Abstract： Aiming at controlling cutting distance of the CNC cutting machine，the material of rubber strip cutting and cutting

requirements were concluded，the selection of main elements，total switching circuit，external circuit connection in general and feeding

speed controlled were designed，and the controlling system based on PLC technology were proposed，cutting distance was controlled

through the combination of stepping motor with frequency changer，and rubber samples about 0.5 centimeters thick were tested after

debugging repeatedly. The results indicate that the system has flexible operation,realizes automation control,and makes the cutting

distance in requirements.

Key words：CNC cutting machine；PLC；cutting distance
