摘　　要：基于解析法设计了盘形凹槽凸轮,并用Matlab进行相关计算输出凸轮轮廓点,给出了具体编程实现。将凸轮轮廓点作为CAD样条曲线的控制点进行凸轮轮廓线的快速建模,建模过程直观且容易实现。最后采用变步长直线插补凸轮非圆轮廓线进行数控加工,提高了加工效率。该方法为盘形凸轮的建模和数控加工提供了参考。The groove cam was designed based on the analytical method,and the detail MATLAB programe was introduced and used to calculate and output cam sharp points,thus the programming realization was given. The sharp curve of cam was built up rapidly by treating CAM contour point as the control point of CAD,and the modeling method is intuitive and easy to implement. Then the variable step size linear was used to have the interpolation cam contour line for computer numeric control machine manufacturing cam,and machining efficiency is improved by using this method. This paper provides a reference for modeling and CNC machining of cam.
