Research of Cutter Track Elimination Algorithm for CNC Cam Grinding Based on Cubic Spline Curve Fitting and Spline Interpolation

Abstract:

Cam is the key component of many important types of equipment. To improve the surface precision of cam, and to eliminate the cutter track, the production data format is analyzed in this paper, a conclusion that the big second derivative is the origin of track is reached. An algorithm to eliminate cutter track is brought forward, spline curve fitting is used to process the discreted data, and spline interpolation is used hereafter such that the second derivative is reduced to an acceptable range. The experiment shows that this method can efficiently eliminate the track on the surface, so as to improve the productivity of equipments.
