Application of CAD/CAM/FEA, reverse engineering and rapid prototyping in manufacturing industry


The paper presents some aspects about rapid prototyping which stays at the base of manufacturing design using CAD/CAM/FEA programs, scanning and measuring machining and its integration in industrial field. A big economical advantage is that products made by rapid prototyping express a low risk failure and the manufacturing process takes less time and lower costs than the conventional techniques. A new gasket for a ball screw used in a bending tube machine was produced by rapid prototyping techniques starting from a broken one. First the broken gasket was scanned by Modela Roland LPX-600 scanning machine obtaining the primary 3D model which is imported to CAD/CAM programs and the final product is achieved on ISEL GFM 4433 milling machine..The gasket mechanical characteristics were investigated by finite element analysis (FEA). FEA provides a way of simulating the gasket design under working condition and an opportunity to understand interactions with the mating machine. Therefore, problems in tooling or mold mating would be minimized. After FEA simulation a new material was chosen in order to increase the mechanical characteristics. The new gasket material improves the tool wear and life, scuff resistance, breaking strength and handling characteristic After that the gasket is assembled on the ball screw of the bending tube machine in order to observe its functional behavior. Keywords— rapid prototyping, reverse engineering, gasket, scanning, milling, FEA.
