Efficient utilisation of both design geometry information and process information is at the heart of modern CAPP systems. The need to consider them both in development and implementation of process planning algorithms and optimisation is the focus of this chapter. The chapter describes a framework for integration of process information in the form of rulebased process selection with geometry data in the form of virtual machining. A rule-based process selection module considers the part geometry and tolerances, and identifies a set of machining processes, tools, and/or machines needed to produce the feature with the required quality. Each selected process candidate is sent to a virtual machining module, which uses the process data and part geometry to generate a virtual machining model and simulates the process in a virtual 3D world enabling the users to verify the process parameters, identify any undesired part/tool collisions, and create an intermediate workpiece geometry required for fixture design. The virtual machining model also enables ranking of alternative candidates for the same feature and verification of the sequence of processes required for a single feature. Procedures and algorithms for both process selection and virtual machining and approaches for their integration are demonstrated on several complex mechanical parts. [ABSTRACT FROM AUTHOR] |
