摘　　要：采用有限元法 ,建立金属陶瓷可转位刀片复杂结构的三维有限元模型 ,加载求解 ,进行位移场和应力场分析 ,计算出刀具的最大位移、应力、应变等 ,以进行金属陶瓷可转位刀具的抗弯强度和抗压强度校核 ,可有利于对切削过程中的力学特性进行深入研究 。A 3D finite element model of the complicated structure of ceramal index-able blade was established by finite element method. By way of adding load solution, the analysis of displacement field and stress field was carried out and the maximum displacement, stress and strain etc. of the cutter were calculated. Carrying out the checking for bending strength and compressive strength of the ceramal index-able cutter could be advantageous to putting up a deep study on the mechanics characteristics during the cutting process, and provide theoretical bases for the design of ceramal index-able cutter.
