By Martin Held

During this monograph the writer provides an intensive computational geometry method of dealing with theoretical and sensible difficulties bobbing up from numerically managed pocket machining. The process unifies clinical disciplines: computational geometry and mechanical engineering. subject matters of useful significance which are handled comprise the choice of instrument sizes, the decision of device paths, and the optimization of device paths. complete information of the algorithms are given from a pragmatic viewpoint, together with info on implementation matters. This practice-minded method is embedded in a rigorous theoretical framework permitting concise assertion of definitions and facts of the correctness and potency of the algorithms. specifically, the development of Voronoi diagrams and their use for offset calculations are investigated in nice aspect. in response to Voronoi diagrams, a graph-like constitution is brought that serves as a high-level abstraction of the pocket geometry and gives the root for algorithmically acting form interrogation and direction making plans projects. eventually, the potency and robustness of the process is illustrated with figures displaying pocketing examples which have been processed by way of the author's personal implementation.
