摘　　要：慢走丝线切割中,零件表面质量要求越高,相应加工时间也就越长,加工时间的长短直接影响加工成本。通过引入粗糙度系数的概念,将加工总时间折算为与切割加工相关的时间,建立了慢走丝线切割成本估算模型,并采用切割实验验证了粗糙度对加工时间仅有较小的影响,合理降低了粗糙度系数取值。最后运用构建的成本模型计算某工件的加工成本,验证了该模型的合理性。In low speed wire cutting,the better the surface quality of the part,the longer the corresponding processing time,and the length of the processing time directly affects the processing cost.By introducing the concept of roughness coefficient,the total processing time is converted into the time related to cutting processing,and a cost estimation model for LS-WEDM is established.The cutting experiment verifies that roughness has only a small effect on processing time,and reasonably reduce the roughness coefficient.Finally,the cost model is used to calculate the processing cost of a workpiece,which verifies the rationality of the model.
