Abstract:A novel fast tool servo system driven by a voice coil motor has been developed,which has the total stroke of 30mm and the maximum acceleration of 920m/s2. The system model was obtained by the experimental process, which was used to design the controller. The micro-lens array, a typical optical surface with complex structure, which was machined, and the experimental results were tested and analyzed. Experimental results indicate that the performances of the developed fast tool servo system satisfy the machining requirements. A good foundation for future application was built in real manufacture.
