Based on phase lock loop technology, a new subdivision technology for the processing of phase or frequency modulate typed sensor signal in gear transmission error measurement of machine tool and a new control principle named two loop zero error interpolation are put forward. Based on the above technologies, the CNC system for the generation motion of gear teeth profiles is developed and used on the CNC reconstruction of Y38A hobbing machine. The results of measuring experiments have showed that the new subdivision technology and the interpolation method are correct, and the developed CNC system has the characteristics such as feasibility, fast interpolating, high precision and better real time performance.
