摘　　要：镗孔加工尺寸误差补偿是控制镗孔加工尺寸分散度、保证零件互换性的一种经济、有效的方法,而镗孔刀具微量补偿装置是实现误差补偿的关键技术之一。针对小深孔钻镗加工环境,设计一套高精度补偿的压电式微量补偿装置,该装置具有微米精度的在线镗削误差补偿功能。设计一种新型的抗振镗杆,有效减少了因加工过程中震动而带来的加工尺寸误差问题。该新型的刀具微量补偿方法能够满足大悬臂小深孔精密加工的要求。Dimension error prediction and compensation for boring is an economic and effective method to control the dimension distribution and to maintain part exchangeability.The trace compensation device for the boring cutter is the key technique to realize error compensation.For small deep hole drilling boring processing,a high precision piezoelectric compensation device was designed.It was of the online error compensation with micron accuracy.In addition,a new anti-vibration boring rod was designed and all error problems from vibration of boring could be effectively reduced.As a new type of error compensation device,it satisfies the requirements of big cantilever,small deep hole and precision processing.
