Abstract In this paper a two step approach for the transformation of design features to manufacturing features is presented. In the first stage of the proposed algorithm, a methodology for handling protrusion features by the decomposition of the surrounding volume into basic, negative, machinable volumes is discussed. In the second stage called the feature refinement stage, relevant manufacturing information is appended to the negative feature model resulting from the first stage. The proposed methodology can be used to support automated process planning. Practical examples and computer implementation in an object oriented feature based design system are also presented.

Initial Geometry

This paper describes a novel method for automated process planning for rough boring of turned components with arbitrary internal geometry from a semi-finished stock. Earlier work has been reported on process planning for boring of components with monotonic internal geometry made from bar stock. This paper addresses the more general problem of process planning of parts with non-monotonic internal feature list from arbitrary given initial geometry, i.e., from a casting or from a semi-finished stock. With the algorithms developed, we are able to achieve full automation of all aspects of the process plan, including operations sequencing, parameter selection, NC code generation, etc. Thus, it becomes possible to go from design to NC code in a fully automated fashion. In the present work we focus on a tightly defined part family, which results in very simple but robust automation algorithms. This is in contrast to much of the reported work on automated process planning, which generally targets broad part families, leading to complex algorithms that fall short of complete design-to-NC automation.
