Abstract
This paper presents an octree subdivision based algorithm of automatic cutter path generation for machining on a numerical control machining centre. Both the stock and the part are represented by solid models. The machining strategy is based on a layer by layer approach taking care of the cutter strength and the variation of the part geometry. This approach allows the problem to be reduced from a three-dimensional to a two-dimensional cutter path generation problem which is solved by a quadtree representation of the plane. The method can be easily extended to include the jigs and fixtures and any other obstacles which would be represented by solid models. Algorithms are described in Pascal-like structure.
