Abstract：Aiming at the problems of drill positioning inaccuracy and unreliability in the process of NC glass drilling，the AC servo and

stepper driving technique was investigated. After the analysis of the structure and principle of the vertical high precision positioning glass

drilling equipment，a high precision positioning control system was established. A method was presented to control drill position based on

AC servo driving system and to drive the dual-drill feeding based on stepping motor. The error of centre hole size，position（referred to

reference）and concentricity were tested. The results indicate that half closed loop feedback control system in AC servo driving system has

enhanced anti-interference ability and decrease stable and dynamic error in the location process. And drilling quality has been enhanced

by controlling speed and feeding of stepper dual-drill. Automatic production can be accomplished by parameters setting and real-time

monitoring with interactive software.

Key words：NC glass drilling；position control；AC servo
