Computer Aided Process Planning for Rotating Parts

Abstract

The paper deals with the development of a generative Computer Aided Process Planning system. The design data, input in the form of question answer session,forms the basis for Blank selection, selection of a Sequence of Operation and Machine tool selection. The Knowledge base of machine tools is built up by the planner to incorporate his shop floor conditions. The system infers on the optimum cutting parameters for each machining operation and calculates the time estimates. The final output is a process plan document covering the complete gamut of machines like power hack saw, keyway milling, lathe, grinding etc. Although, the system uses the classical software development features it closely emulates an Expert System. Work is on to convert this system to a complete Expert System consisting of IF-THEN-ELSE rules and offering further flexibility to the user.
