| 摘 要： | 钛合金材料的各种特点决定了其难切削的加工性能,针对一种低成本钛合金Ti8LC材料进行了切削加工性能的试验研究.运用有限元法,再现了钛合金切削加工过程,得出了切削参数对主切削力及进给抗力的影响规律,结果表明,随着切削深度的增加,主切削力和进给抗力均有大幅增长,而进给量对切削力的影响不大.而通过进一步的切削加工试验,分析了不同切削速度、进给速度、进给量等工艺参数对钛合金切削加工时的主切削力、进给抗力等的影响,结果表明,由于实际切削中的刀具磨损问题,切削力较仿真切削力大许多.因此,采用目前的涂层硬质合金刀具,该钛合金材料的切削速度应在( 120～160) m·min-1,否则将引起剧烈的刀具磨损而使切削力陡然增加.

| Abstract: | The various characteristic of titanium alloy decided its difficulty cutting performance.Cutting performance tests of a new kind of low-cost titanium alloy-Ti8LC were put up.With the finite method,the cutting process of the titanium was reappeared.At the same time,the rules which influenced parameters on cutting resistance and feeding resistance were obtained.The main cutting resistance and the feeding resistance were raised greatly along with the increase of the cutting deepness,whereas the feed-rate had li... |
