摘　　要：探讨了电解修整金刚石成型砂轮中阴极的设计计算方法,建立了阴、阳两极间电位分布的数学模型,并以其作为计算边界条件,采用有限元法和cosθ法求解阴极形状。计算结果表明,在陶瓷镶块的粗加工或半精加工过程中,可以采用cosθ法修整成型砂轮,以简化阴极的设计与制造;在陶瓷镶块的高精加工中,采用有限元法可设计出更精确的阴极形状。The design and calculation method of the cathode for electrolysis finishing of diamond form grinding wheel is discussed,the mathematical model of electrical potential distribution between the cathode and the anode is cre ated.With the model as boundary condition,shape of the cathode is solved with the finite element method and the cosθmethod.It is shown by calculation that form grinding wheels for rough machining and semi finishing of ceramics insert blocks can be finished with the cosθmethod so that the design and manufacture of cathodes is simplified,and the more precise shape of the cathode can be designed with the finite element method for high accuracy finishing.
