【摘要】 以硬质合金刀具铣削奥氏体不锈钢的铣削力试验为基础，得出了铣削速度提高时铣削力的变化规律，并用Ｉ－ＤＥＡＳ软件进行了有限元分析，得出了发生粘结破损时刀具前刀面附近应力场分布的规律，最后从应力场的分析出发，探讨了硬质合金刀具粘结破损的产生机理更多还原

【Abstract】 On the basis of the milling－stress expriement when carbide alloy tools in cut-ting the strainless steels,we found the milling－stress transfomation rule with the cutting speedincrease；By the method of infinite element analysis of the I－DEAS softwore in workstation．itis found the stress field display rule of the tools in sticking－welding fracture.At last,fromthe stress field analysis,we discuss the sticking fracture mechanism of carbide alloy tools．更多还原
