摘　　要：本文旨在探讨在VDL-600A立式加工机床上使用KC72S刀具对蠕墨铸铁进行铣削时,铣削速度、进给量和背吃刀量对切削力的影响。通过对当前蠕墨铸铁铣削切削力研究现状的分析,发现铣削速度是对切削力影响最为显著的因素。较高的铣削速度会导致更大的切削力,这可能是由于高速铣削时刀具与工件之间的摩擦力增加所致。相比之下,背吃刀量和进给量对切削力的影响相对较小。这可能是因为这两个因素对切削过程中刀具与工件之间的接触面积变化不大。对蠕墨铸铁进行铣削时,需要着重考虑调整铣削速度,相对而言,背吃刀量和进给量的调整对切削力影响较小。This paper aims to discuss the effects of milling speed,feed and back feed on cutting force when using KC72S tool on the VDL-600A vertical machining machine for milling vermicular graphite cast iron.Through the analysis of the current research status of milling force of vermicular cast iron,we find that milling speed is the most significant factor affecting cutting force.Higher milling speeds result in greater cutting forces,which may be caused by increased friction between the tool and the workpiece during high-speed milling.In contrast,the amount of back eating and feed has a relatively small effect on the cutting force.This may be because these two factors do not change much in the contact area between the tool and the workpiece during the cutting process.When milling vermicular cast iron,it is important to consider adjusting the milling speed,and relatively speaking,the adjustment of the back feed and feed has little effect on the cutting force.
