摘　　要：选用具有不等齿距和减振刃带结构的A型铣刀,具有不等齿距和双直线后角的B型铣刀以及具有等齿距结构的C型铣刀作为实验刀具,针对这几款不同几何结构的铣刀进行316L切削加工性能的研究,利用测力仪测定加工过程中的切削力,通过频谱图和加工表面的粗糙度,分析几何结构对切削性能的影响。结果表明:具有减振刃带和不等齿距设计的A型铣刀在切削316L不锈钢时,切削力降低16%左右,加工表面粗糙度提升25%左右。Type A milling cutter with unequal pitch and damping edge belt structure,type B milling cutter with un⁃equal pitch and double straight back angle,and type C milling cutter with equal pitch structure were selected as experimen⁃tal tools.The 316L cutting performance of these milling cutters with different geometric structures was studied.The cutting force in the machining process was measured by a force meter.The effect of geometric structure on cutting performance was analyzed by spectrogram and machining surface roughness.The results show that when cutting 316L stainless steel,the cut⁃ting force of the type A milling cutter is reduced by about 16%,and the surface roughness is increased by about 25%.
