Cutter Location Data Generation Under Consideration of Control System of Machine Tool for High Speed and High Accuracy Machining

Abstract

Drive control of machine tools is based on linear interpolation drive. When machining of curved surfaces using linear interpolation drive, in the cases of small distance driving, there are problems that feedrate does not reach the indicated speed and machining accuracy and surface quality decrease due to big acceleration and deceleration for control axis. In order to solve such problems, a method to generate cutter location data under consideration of sampling time of the control system is proposed in this study. The effectiveness of the proposed method is confirmed by simulations and experiments.
