Fast Modeling and Variable Step Size Tootpath CNC Manufacturing of Concave Cam

WU Xin-liang;Mordern Engineering Training Center,Xiamen University of Technology;  
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.
