摘要/Abstract

摘要： 研究了钛合金高速超声椭圆振动铣削中振幅对加工表面完整性的影响。首先基于高速超声椭圆振动铣削过程中刀具-工件的运动学特点和实现分离断续切削条件，建立了切屑厚度模型以及考虑刀具-工件有效参与铣削的刀具动态切削后角模型。针对振幅对高速超声椭圆振动铣削的影响进行了微量润滑条件下的高速超声椭圆振动侧铣削钛合金试验，对不同振幅条件下的高速超声椭圆振动铣削过程中的切削力、工件表面质量、残余应力、亚表层显微组织以及表面显微硬度进行了详细研究。试验结果表明：高速超声椭圆振动铣削过程中的平均径向切削力值随着振幅的增大呈现减小的趋势。高速超声椭圆振动铣削中振动幅值对于工件表面完整性的影响显著。高速超声椭圆振动铣削表面粗糙度值随着振动幅值的增大而增大；高速超声椭圆振动铣削表面残余压应力值随着振动幅值的增大而增大；高速超声椭圆振动铣削的变形层厚度以及晶粒细化程度随着振动幅值的增大而增大；高速超声椭圆振动铣削表面加工硬化程度随着振动幅值的增大而增大。

Abstract: The effect of vibration amplitude on machining surface integrity in high-speed rotary ultrasonic elliptical vibration milling Ti-6Al-4V is studied. Firstly, based on the kinematic characteristics of the tool-workpiece and the separation criteria of intermittent cutting condition during high-speed ultrasonic elliptical vibration milling, a chip thickness model and the tool dynamic cutting relief angle model with consideration of the tool-workpiece effectively cutting participation in milling are established. Aiming at investigating the effects of vibration amplitude on high-speed ultrasonic elliptical vibration milling, high-speed ultrasonic elliptical vibration side milling of titanium alloys experiments under minimum lubrication condition are conducted. The cutting forces, surface quality, residual stress, subsurface microstructure and machined surface microhardness during high-speed ultrasonic elliptical vibration milling under different amplitudes are investigated in detail. The experimental results show that the average radial cutting force during high-speed ultrasonic elliptical vibration milling shows a decreasing trend with increasing amplitudes. The vibration amplitude in high-speed ultrasonic elliptical vibration milling has a significant effect on the surface integrity of the workpiece. The surface roughness value of machined surface in high-speed ultrasonic elliptical vibration milling are increased with the increase of vibration amplitudes. The residual compressive stress value on the machined surface in high-speed ultrasonic elliptical vibration milling are increased with the increase of vibration amplitudes. Thickness of the deformed layer and grain refinement degree beneath the machined surface in high-speed ultrasonic elliptical vibration milling are increased with the increase of the vibration amplitudes. Hardening degree of machined surface in high-speed ultrasonic elliptical vibration milling are increased with the increase of vibration amplitudes.
