Abstract

Based on the cubic spline interpolation for curve-fitting of molded lines of cam, an optimization method to reduce deviation of cam profile curve-fitting is raised. Calculate the given data of lift table by means of cubic spline interpolation and use curvature comb function of software UG to have a fairness analysis for cam profile curve. Cam profile curve will be produced after a calculation of cam lift data by cubic spline function. Then, utilize the curvature comb function of software UG to analyze the deviation of curve-fitting of the profile curve and implement a faring processing. With a contrast and analysis of curvatures before and after the faring processing, it is clear that cam profile curve has been improved obviously, which proves the method to be effective.
