摘　　要：提出一种切割幅面宽度达到其直径2/3的组合结构金刚石圆锯片基体。利用有限元软件ANSYS对1800mm的组合结构金刚石圆锯片进行了变形和应力分析,分析总结出了组合结构金刚石圆锯片在仅受离心力、锯切力、离心力和锯切力共同作用下的变形和应力分布的特点、规律和相互影响关系。通过正交表设置不同的加工工艺参数,经过多次有限元分析计算得出组合结构金刚石圆锯片二种最优参数组合：进给速度200 cm/min、线速度30 m/s时,切割深度2-2.5 cm为好;线速度30 m/s、切削深度1 cm时,进给速度500 cm/min为好。A new combined diamond saw blade is proposed and the cutting breadth can reach two thirds of its diameter with this new blade. The calculation of the deformation and stress of Ф1800 mm combined diamond saw blade is calculated by means of finite element software ANSYS. The character, rule and correlation of deformation and stress are analyzed when combined diamond saw blade is under the action of centrifugal force, cutting force, and under combined action of the two forces. According to different parameters by orthogonal tables, finite element calculation was done for many times and two optimum parameters of cutting were obtained： the depth of cutting is 2-2.5 cm when the feed speed is 200 cm/min and circular linear speed is 30 m/s; the feed speed of cutting is 500 cm/min when the cutting depth is 1 cm and circular linear speed is 30 m/s.
