    摘要:

    为了提高刀具对难加工材料的切削加工性能,降低切削力,延长刀具寿命,采用激光加工技术在TiAlN涂层刀具前、后刀面上制备出平行于主切削刃的沟槽型织构,对比研究变切削参数条件下铣削镍基合金的切削力变化情况。结果表明:在低转速、小吃刀量、低进给速度情况下,后刀面织构刀具的切削力小于前刀面织构刀具;背吃刀量对前刀面织构刀具的切削力增幅影响最大;主轴转速对后刀面织构刀具的切削力增幅影响最大。

    Abstract:

    In order to improve the performance of cutting tool for difficulttomachine materials, to decrease the cutting force and to prolong tool life, the manufacture of microgroove texture on the rake and flank face of TiAlN coated cutting tool parallel to the main cutting edge with laser processing technology is prompted. The varied condition of cutting forces in milling nickel-based alloy under diverse cutting parameters was studied with comparison. The results show that the cutting force of the flank face textured tool is less than the rake face textured with low spindle speed, small cutting amount and low feed speed. The biggest effect of cutting force increment is the milling depth for the rake face textured tool, and so as the spindle speed for the flank face textured tool.
