基于钛合金切屑形态的铣削试验研究

Milling Experiment Research Based on Titanium Alloy Chip

通过对TC4钛合金锻件进行12组铣削实验,得出了切屑外观具有锯齿特征且随着铣削深度的不断增大发生由紧密螺旋状逐渐变为松散卷曲状的结论。利用数学相关分析和建立回归方程的方法,明确了金属去除速率和铣削深度之间的高度线性相关关系。通过综合考虑钛合金的加工质量和加工效率,确定了铣削深度范围和特定情形下较为理想的金属去除速率,为钛合金铣削加工提供一定的生产指导。

In this paper, we get a conclusion by 12 sets of milling experiments on TC4 titanium alloy that the chip morphology of TC4 titanium alloy appears sawtooth feature and will change gradually from the tight spiral to the loose curl with the increasing milling depth. By means of mathematical correlation analysis and establishment of regression equation, the highly linear relationship between metal removal rate and milling depth is clarified.By considering the quality and efficiency of titanium alloy processing,the milling depth range and the ideal metal removal rate in the specific case are confirmed, which can provide some production guidance for titanium milling.
