Fast Tool Servo Driven by Electromagnetic Force Applied in Freeform Surfaces Machining

Article Preview

Abstract:

Fast tool servo is increasing applied to manufacture optical freeform surfaces, which are adopted in aerospace, imaging, bioengineering, energy fields to improve the performance of the system, simplify the structure of the system and lower cost. The existing FTS have limited stroke and bandwidth. FTS driven by electromagnetic force is discussed. The analysis of the magnetic circuit, the requirements of the system and the corresponding design parameters are studied. The designed FTS can realize the bandwidth of 0-100kHz with a special designed driver.
