Eimermachert3" - The Rapid Design System (RDS) is a feature based design, fabrication, and inspection system. Research and development of the RDS has been sponsored by the United States Air Force. The Fabrication Planning (FP) Module of the RDS is being developed by the University of Dayton. The FP module automatically creates a process plan for machining a metal part. The research addressed herein deals with the User Interface for the review and modification of a process plan. The Fabrication Planning Module automatically creates a plan using information from the Feature Based Design Environment (FBDE) of the RDS. It integrates this information with the information received from a program/database called MetCAPP TM . The process plan is created in a series of steps: feature translation, feature sequencing, setup generation, and operations generation. The purpose of the Planning Window and User Interface is to give a designer, machinists, or process planner the ability to automatically generate and manipulate a complete process plan. 92-11971 92 5 01" 009 0 llll By using the user Interface, the final process plan can be modified in many different ways. The translation of a design feature to a more appropriate MetCAPPTM manufacturing feature can be accomplished. Manufacturing features can be moved between setups, setups can be added or deleted, and machining operations generated by MetCAPPTM can be changed. Finally, when an acceptable plan has been generated, the code to run a Computer Numerically Controlled (CNC) machine is generated. The research here addresses the process of generating and changing a process plan. Work was done in the area of feature translation, the effect of changing a setup, and the effect of changing the machining operations. At each step in the process, the designer, process planner, or machinist is given the opportunity to accept what has been generated or change it. By allowing changes, the results of both future and prior steps may be affected. Code was written that tracks these affects and regenerates the necessary parts of the plan. This thesis documents the parts of the plan that may be changed, the affects of making such changes, and the code to implement the research results.
