摘　　要：以难加工材料TC11钛合金为研究对象,针对TC11钛合金内排屑深孔钻削时存在断屑困难等问题,开展TC11钛合金BTA深孔钻削试验研究。为了获得理想的切屑形态,分析BTA深孔钻削机床的主轴转速和进给量对切屑形态的影响规律。试验表明,当转速为98r/min、进给量为0.16mm/r时,切屑呈短螺旋形状,导向块磨损相对最小,有利于顺畅排屑,加工过程稳定。本研究为钛合金等难加工材料的深孔钻削参数的选择提供了依据。Taking TC11 titanium alloy,which is difficult to be machined,as the research object,an experimental study is carried out on TC11 titanium alloy BTA deep hole drilling in view of the difficulties of chip breaking in deep hole drilling.In order to obtain the ideal chip shape,the influence law of spindle speed and feed rate of BTA deep hole drilling machine tool on chip shape is analyzed.The show that when the speed is 98r/min and the feed is 0.16mm/r,the chip presents a short spiral shape and the guide block wear is relatively minimum,which is conducive to the smooth chip discharge and stable machining process.The research in this paper provides a basis for the selection of deep hole drilling parameters for titanium alloy and other difficult materials.
