Machining process planning using Decomposition of Delta Volume

A methodology for decomposition of material removed volumes so called Delta Volumes according to the natural sequences of machining is proposed. Tool classification and coding system for automatic characteristics and parameter extraction is presented. Algorithms for identification of major access directions and machining complexity and rules determining operations and tools for roughing and finishing are presented. This article suggests a technique that generates machining operation sequences with appropriate combinations of tool and machine directly from the 3D model of a part and a given block.
