Abstract
In this paper, a novel method is proposed for identifying local interference region and generation iso-scallop tool paths based on triangular mesh model for 3-axis ball-end milling. With our method, the principal curvatures and directions at vertices have been computed first and a recursive merging algorithm for segmenting local interference regions is developed. In addition, a method of generation tool path with constant scallop height for local interference region is also presented. Some illustrative examples are tested that indicate the feasibility and availability.
