铣刀片的应力场分析【摘要】 铣削属断续切削，切削过程中刀片受力非常复杂，力的大小和方向随时变化，刀片的失效形式主要为冲击破损。因此，采用有限元法对铣刀片应力场进行分析，以寻求减少刀片破损的刀具最佳几何角度，对于铣刀片槽型的开发具有指导意义。 1．引言 铣削属断续切削，切削过程中刀片受力非常复杂，力的大小和方向随时变化，刀片的失效形式主要为冲击破损。因此，采用有限元法对铣刀片应力场进行分析，以寻求减少刀片破损的刀具最佳几何角度，对于铣刀片槽型的开发具有指导意义。2．面铣切削加工坐标系统的建立图1面铣切削加工坐标系统 面铣切削加工坐标系统由刀体坐标系和刀片坐标系组成，如图1所示。 在刀体坐标系中，Y轴为铣刀轴线，X轴在基面内过刀尖与Y轴相交。在刀片坐标系中，y1轴通过主切削刃，x1轴通过副切削刃，刀片前刀面在x1o1y1平面内。铣刀半径为R=OO1，铣刀前角为g0，刃倾角为ls，主偏角为K，法向前角为gn。 面铣刀无论具有何种几何角度，都可看作是由刀体坐标系经过一次平移和三次旋转而成，可用矩阵表示为其中A11=cosgnsinhr+singnsinlscoshrA12=cosgncoshr-singnsinlssinhrA13=singncoslsA21=-coslscoshrA22=coslssinhrA23=sinlsA31=-singnsinhr+cosgnsinlscoshrA32=-singncoshr-cosgnsinlssinhrA33=cosgncoslstggn=tgg0cosls图2 切入冲击力的方向 3．切入冲击力方向的确定 铣削与车削的不同之处在于铣削为断续切削，存在着切入、切出过程，铣刀的破损主要是由机械冲击力引起的。因此，首先要确定铣刀切入瞬间冲击力的作用方向。铣削时，铣刀高速旋转，工件缓慢进给，若忽略进给运动(因进给运动速度仅为铣刀运动速度的约1/4)，铣刀切入冲击力的方向应该在刀具相对工件运动的切线方向上。如图2所示。由图1可知，切入冲击力方向为Z轴方向，力F分解到刀片坐标系中为
