| dc.description.abstract | The use of CAD systems for the mold design of sheet materials has been used for a long time in the automobile industry. Mold design requires knowledge of sheet materials and the process of making molds. With the rapid development of the automobile industry, speeding up the product cycle of manufacturing sheet metal has become a goal for automobile factories This is especially important for marketing after the production is finished. It is hoped that, by the use of reverse engineering for automating the CAE and building process, the process of converting gypsum mold to data usable by CAD systems can be improved.
The process of making sheet metal molds requires four steps: drafting, trimming, flanging, and pressing. In each of the steps, parameters and variables in the CAD model need to be modified according to the function for the sheet metal. To simplify the manufacturing process, we must know the requirements to be able to finish the process.
This paper discusses each step in the process of drawing automobile sheet metals using a CAD system. We run a demonstration and summarize the application process, operation steps, and problems encountered in using a CAD system. We also show methods that improve the whole design process. | en_US |
