本文介绍了用于加工非圆形孔的快速刀具伺服系统的机械和伺服控制设计。旋转镗杆动态改变切削深度以加工非圆形孔，例如发动机活塞活塞销孔中的孔。压电致动器驱动的快速刀具伺服系统具有 60 微米的位移和约 400 Hz 的第一固有频率。讨论了快速刀具伺服系统鲁棒重复控制的设计，并给出了用于生成椭圆形孔轮廓的切削刀具运动的实验结果。版权所有 © 2006 by ASME
This paper presents the mechanical and servo control design of a fast tool servo for machining noncircular bores. The rotating boring bar varies the depth of cut dynamically to machine noncircular bores, such as those in engine piston gudgeon pin holes. The piezoelectric actuator driven fast tool servo has 60 micron displacement and about 400 Hz first natural frequency. The design of robust repetitive control of the fast tool servo is discussed and experimental results of cutting tool motion for generating oval bore profiles are presented.Copyright © 2006 by ASME
