摘要
针对高速切削钛合金时切削力的问题,利用有限元分析软件Abaqus的Johnson Cook材料模型及Johnson Cook断裂准则,对钛合金高速切削切削力进行了仿真研究,分析钛合金高速切削加工过程中各切削参数(包括进给量、切削深度和切削速度)对切削力的影响.结果表明,切削力、进给力、单位面积切削力和单位面积进给力都随速度的增大而减小;但随着进给速度的增大,切削力和进给力都增大,而单位面积的切削力和进给力都减小.
The aim of this research was to investigate cutting force during high speed machining titanium alloy.Johnson-Cook materials model and fracture criterion of commercial finite element software Abaqus was used to simulate high speed machining Ti6Al4V.It was Analyzed that The influence of the cutting parameters（including feed rate,cutting depth,cutting speed） on the cutting forces.The results shown that cutting force,feed force,specific cutting force and specific feed force reduced with increases in cutting speed,cutting force,feed force increased and specific cutting force,specific feed force reduced with increases in feed rate.
