摘要
硬质合金刀具在不锈钢加工中，其刀具耐用度主要是取决于后刀面边界磨损而不是主切削刃后刀面的平均磨损量。为了提高刀具耐用度，就必须减小后刀面边界磨损。本文对奥氏体不锈钢（ＳＵＳ３０４） 在车削及铣削加工中，采用Ｍ２０ 、Ｋ２０ 和Ｚ２０ 材料以及ＴｉＮ、Ｔｉ（Ｃ，Ｎ） 和（Ｔｉ，Ａｌ）Ｎ
In many cases of stainless steel cutting operations with carbide tools,a tool life strongly depends on flank notch wear of depth of cut rather than average flank wear of main cutting edge.To improve a tool life in this case,therefore,the flank notch wear must be depressed to generate.In this study,the notch wear of coated carbides in turning and milling operations of austenite based stainless steel was investigated in relation to mainly substrates corresponding to M20,K20 or Z20 and PVD coated layers such as TiN,Ti(C,N)and (Ti,Al)N layers.
