钛合金BT20端铣试验研究

Experimental Study on the End Milling Titanium Alloy BT20

传统的钛合金加工工艺因其切削速度低、刀具耐用度低、机床功率不足的缺陷 ,导致了加工效率低。针对上述问题 ,对钛合金BT2 0进行了多次端铣试验 ,发现采用先进的刀具材料 ,优化刀具角度 ,使用大功率机床 ,在保证必要的刀具耐用度的前提下 ,完全可以提高切削速度 ,从而提高钛合金加工效率。

In the traditional titanium alloy process the cutting efficiency is lower, this is because both cutting speed and tool life are lower and machine power is not enough. The paper describes the experiment on end milling titanium alloy BT20. The experiments show that the cutting speed can be increased evidently when adopting advanced tool material, optimizing geometric parameters and using larger power machine, premising necessary tool life.
