摘  要：
实验研究了利用进给方向超声振动辅助微细铣削对零件加工尺寸精度的影响。以2A12为实验工件材料,利用一个超声振子带动工件沿进给方向振动进行铣槽实验,加工后对槽宽进行了精确测量。通过单因素实验分析了施加超声振动前后加工槽宽的变化,结果表明超声振动有助于减小加工尺寸偏差,而大的振幅更有利于提高加工尺寸精度;基于日本田口方法,通过全因子实验考察了主轴转速、每齿进给量、振幅对加工尺寸偏差的影响并进行了加工参数优化。

摘  要：
The purpose is to investigate the effects of the ultrasonic vibration on dimensional accuracy in micro milling process.Several slot-milling experiments were conducted with aluminium alloy as the workpiece material.The desired vibration was proposed from the workpiece side by an ultrasonic vibrator.The width of slot produced by end milling was precisely measured.A one-factor experiment was conducted at first to analyze the variation of slot width before and after ultrasonic vibration was applied,and the experimental results indicated that ultrasonic vibration made contribution to the decrease of size deviation and larger amplitude tends to reduce the slot width oversize.A full-factor experiment was carried out accordingly based on Taguchi method to optimize the parameters involving spindle speed,feed per tooth and vibrating amplitude.
