【 摘 要 】

The primary objective of this research is to improve dimensional tolerances and reduce total manufacturing time of precision milling operations through the implementation of force-feedback machining.Force-feedback machining consists of using real-time cutting force measurement integrated with high bandwidth actuation to provide active error compensation of tool deflection. This research focuses on the development and implementation force-feedback machining using miniature (< 1 mm diameter) ball end mills.Due to the thin geometry of these tools, deflection of the tool during machining results in significant form error of the machined part. A piezoelectric two-axis force feedback actuator was designed and developed to measure and compensate for tool deflection errors of miniature ball end mills.Geometric form error was reduced by 75 % thru the application of force feedback machining.
