This article discusses structure of control system based on UMAC motion control card, and basic principle of processing aspheric optical parts by using tangent rotary method. Aiming at common meridian profile curve equation ofaspheric optical parts, a concrete calculation method of PVT control trajectory is presented, which is based on UMAC motion control card and applied for processing aspheric optical parts. The motion trajectory equation of each axel in tri-axial linked system is obtained through this method. Through simulating displacement-time and speed-time of each axel by using MATLAB, and at the same time comparing and analyzing curves of displacement-time and speed-time, then obtain the method of processing arbitrary aspheric surface by using PVT control algorithm of UMAC motion control card.
