| Summary: | 碩士 === 健行科技大學 === 機械工程系碩士班 === 103 === This study using a white-light scanner retrieve the object points and a lot of data capacity, depth dimension variation automotive stamping parts of the case and compare 3D errors. Through analysis of the differences can be clearly compare the size of the parts final size and CAD, and the establishment of mechanisms for correcting feedback analysis.
First, the final size of CAE analysis and forecasting automotive sheet metal parts, and select the appropriate processing parameters, the development of the initial test mold, and the automobile sheet metal parts stamping punch through, the white-light scanner measure the actual of the 3D model with three-dimensional point data. The error feedback correction initial mold test mold, in order to quickly obtain an acceptable die size through such processes to build 3D error feedback methods.
On the other hand, a punch die design for analyzed different conditions of the finished appearance of the finished product looks conditions, such as urging the size of the friction size, punch size so the conditions for analysis, pick out the most Fit. And the best results obtained by the analysis of a model, a Material Testing Machine (MTS) state analog die stamping, punching finished and after scanning through white-light scanner, and the scanned data and simulation results were compared to verify the analysis results effectively and analyze the the difference of stamping CAE.
