Development of a CAM System for the Rapid Prototyping Environment

Abstract

The goal of this research was to develop a Computer-Aided Manufacturing system for rotational parts for application to small-scale manufacturing. The developed software, DPCAM, was to provide an intermediate step between the total automation of a Rapid Prototyping Center and current commerically available systems. This was achieved by applying technologies already developed for the total automation problem to the intermediate solution. Modules included in the DPCAM package include: -Design Retrieval -Part Evaluation -Estimation -N/C Coding Generation - Equipment Management The information from the modules is presented to the user through a series of "user friendly" graphics windows. While each of these functions is a "state of the art" system, incorporating techniques such as Group Technology and Manufacturability Analysis, the major contribution is their integration into a single complete CAM package. The finished system is implemented on a "PC" style computer and tested at the University of Maryland's Flexible Manufacturing Laboratory.
