A New Method of Point-to-Point Comparison Interpolation for Involute

Abstract:

This paper presents a new interpolation method for involute in polar coordinate system based on pulse incremental algorithm and point to point comparison method. The new idea is that the diameter deviation of the base circle at any interpolation point is calculated and introduced to be a criterion to determine the feeding direction of next step. Consequently, the interpolation computing becomes very simple and high contour accuracy can be obtained. With slight modification of numerical control (NC) system, this method can be realized on NC milling machines equipped with two simultaneous movement axes. A case study has shown that this method is feasible and effective.
