切削Inconel718表面粗糙度的试验研究

Experimental Research on Surface Finish of Cutting Inconel 718

利用涂层硬质合金刀具对Inconel 718进行了高速切削试验,对不同切削参数下刀具的切削用量及刀具磨损对工件表面粗糙度的影响进行了研究。分析结果表明进给量对已加工表面的粗糙度影响最大,切削深度次之,切削速度最小;刀具进入正常磨损阶段后,表面粗糙度减小,处于最佳的切削状态。

The cutting tests of high speed turning Inconel 718 using coated carbide tool is presented.The influences of cutting parameters and tool abrasion on surface finish are studied.The results show that feeding affected on the surface finish of machined surface has been most,then is cutting depth,cutting speed is minimal.After entering normal wear stage,the surface roughness decreases,and cutting condition is optimum.
