摘要

為了研究負稜主刃車刀當刀尖磨耗時，切削不銹鋼材的切割力量，刀尖溫度及主切屑與第二切屑的生成情形，一種新的切削力學模式在此建立。此模式伴隨著刀具在磨耗狀況下，切削不銹鋼時其產生的剪切面積變化以預測切削力，結果理論值與實際值很接近。

To study the cutting forces, the carbide tip's surface temperature, the mechanism of secondary chip and main chip formation of turning stainless steel with a chamfered main cutting nose radius worn tooIs. A new force model incorporating tool worn factor and using the variations of shear plane areas occurring in tool worn situations are presented in this paper. The results show a good agreement between the predicted and measured forces.
