一、引言随着现代工业的发展,新材料不断出现,同时,新的刀具材料也相应出现,以适应切削加工的需要。这些新工件材料的加工性和新刀具材料的切削性都需要进行鉴定,因此常常要进行刀具耐用度试验,建立刀具耐用度方程,用以定量地衡量刀具材料的切削性能或评定工件材料的可加工性能,并判 I. INTRODUCTION With the development of modern industry, new materials are appearing constantly. At the same time, new cutter materials appear correspondingly to meet the need of cutting. The machinability of these new workpiece materials and the machinability of new tool materials need to be identified, so tool durability tests are often performed to establish the tool durability equation to quantitatively measure the cutting performance of the tool material or to evaluate the workpiece material Processing performance, and sentenced
