摘要
以钛合金深孔钻削刀具为研究对象,针对钛合金材料的难加工特性,选择了几种常用的硬质合金刀片材料,并优化选择不同的刀片几何参数,进行了深孔钻削试验。通过分析试验结果,确定出适合加工钛合金材料的深孔钻用刀片材料为YT726,其磨损特性优于其他刀片材料,钻削47.4mm钛合金深孔时,比较合理的刀片几何参数为前角γo=7°、后角αo=12°、余偏角ψr=15°、钻头偏心量e=3.8mm。
This paper took titanium alloy deep-hole drilling as a studying object. According to the characteristics difficult to cut of titanium alloy, several cemented carbide tool materials which are widely used in China at present were selected in the tests of machining titanium alloy workpieces. It is determined that deep--hole tool material YT726, whose attrition characteristics surpasses others, is suitable to cut titanium alloy material through deep-hole drilling tests and when drilling titanium alloy deep-holes, whose diameter is φ47.4mm, the optimum geometrical parameters is γo=7°,αo=12°, ψt= 15°,e=3.8mm.
