비축대칭 타원형 제품의 공정설계 전문가 시스템의 개발 = Development of Process Planning Expert System for Non-Axisymmetric Elliptical Products

다국어 초록 (Multilingual Abstract)

The accumulated know-how and trial-and-error procedures are known as the best ways to determine blank shape and dimensions. One of the most important steps to determine the blank shape and dimensions in deep drawing process is to calculate the surface area of the product. The application of the surface area calculation to non-axisymmetric deep drawing process has not been published yet. A computer-aided process planning (CAPP) system for rotationally symmetric products had been developed. However, the application of the process planning expert system to non-axisymmetric components has not been reported yet. In this research, therefore, the process planning expert system for non-axisymmetric deep drawing products with elliptical shape was constructed for a design of blank shape and process planning of deep drawing products by using an AutoLISP function of AutoCAD software. The expert system for elliptical deep drawing products is constructed to recognize the geometry of the product in the major and minor axes by drafting in another two layers on AutoCAD software. This system consists of recognition of input shape, shape reading, three-dimensional (3-D) modeling. blank design and process planning modules, respectively. The process planning expert system would be very useful to reduce lead-time for manufacturing and improve an accuracy of products.
