摘要

在镗削加工中，由于镗杆长颈比较大，因此，普遍存在镗削振动问题，这种振动限制了切削效率，影响了工件表面质量。本文提出以压电振动干扰抑制镗削振动的设想，建立了含有压电控制单元的镗削振动系统动力学模型；基于该模型设计了实验装置。理论仿真和实验分析结果表明，该装置能够有效抑制镗削过程中镗杆的振动，且结构简单，易于实现。

Abstract

Since a boring bar is usually with high length-to-diameter (L/D) ratios, it is inclined to vibrate. Vibration problem exists in boring bars during boring process. The vibration limits the remove rate according to the method of making use of vibration to control intrinsic vibration, A cantilever-beam system dynamic model is established made up of piezoelectric sensor and actuators. A controlling circuit based on displacement-feedback strategy is designed to drive the piezoelectric actuator, furthermore, to actively control the vibration. The result of simulation and experiment indicates that it can restrain the vibration of boring bar effectively during cutting process. On the other hand, it is simple and practical to implement.
