| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 99 === This study attempts to develop a Computer-aided Process Planning (CAPP) system in the Pro/Engineer 3D CAD environment suitable for progressive press tooling. The main research topics include: (1) automatic unbending of a sheet metal part and automatic hole-filling (2) automatic generation of a blank strip, (3) strip layout planning for punching operations, (4) strip layout planning for trimming operations, and (5) strip layout planning for bending operations.
The process planning system developed in this study mainly focuses on the design of metal strips. The basic concept is to have the strips assembled in sequence using a number of single strips. Each strip is assembled using components and outer metal strip modules. This system is suitable for metal strip components of any format. The generated strips are very conducive to design changes. The operations for design changes use intuitive effects to make the system operation easy to understand.
This study explains the basic research method, and also explains the use of software tools including Pro/Toolkit, MFC, and Visual C++ for system development. Practical case studies have been executed to verity the feasibility of the CAPP system in progressive press tooling.
