Abstract

The practically effective method for partitioning freeform surfaces is presented. Based on the surface curvatures, a freeform surface is partitioned into convex, concave and saddle-like regions in which the chain code technique is applied to determine the boundaries of each region. The curves of the boundaries are used as the factor to trim the surface so that each region can be separately machined. A Matlab program was developed to perform the surface partitioning task and obtain the coordinates of all points on the boundaries. The freeform surface reconstruction and simulation of the tool path of partitioned regions were illustrated via Pro/Engineer Wildfire 2.0.
