Abstract

In this paper, a mechanistic model-based force feedback scheme is presented for improving the tracking performance of radial contour turning (also known as the non-circular turning process) with a voice-coil actuator. The current form of voice-coil actuation mechanism (with acceleration feedback) is briefly described and its limitations for high frequency disturbance rejection are identified. Stability issues for the proposed force feedback scheme are discussed via small gain theorem. Tracking performance improvements due to the force feedback scheme are investigated via simulations for different types of non-circular contours and cutting conditions. The effects of various process parameters on relative tracking improvements are also analyzed.
