摘要：

In this paper we describe algorithms for generating NC tool paths for machining of arbitrarily shaped 2 1/2 dimensional Pockets with arbitrary islands. These pocketing algorithms are based on a new offsetting algorithm Presented in this paper. Our offsetting algorithm avoids costly two-dimensional Boolean set operations, relatively expensive distance calculations, and the overhead of extraneous geometry, such as the Voronoi diagrams, used in other pocketing algorithms.
