碩士 === 元智大學 === 機械工程研究所 === 81 === The design of a CNC full-mold casting model machine was presented. The full-mold model is an essential intermediate process for making automotive press dies. To date, it is still rely on manual operation which results in low efficie- ncy and accuracy. Therefore, a CNC type full-mold model making machine with multi-functions of measurement and mach- ining is of great demand to the automotive die industry. System design of the machine includes four major subsys- tems. They are mechanical and mechanism design, PC-based CNC controller, static and dynamics precision verification and error compensation, and reverse-type CAD/CAM system. The mechanical and mechanism design was analyzed by the I-DEAS CAD/CAE package for its assembly interference check, mechan- ism simulation, static stresses and deformation, and natural frequency modes. Potential design defects were identified and were improved through parameters studies. Major functio- nal requirements and design specification of CNC controller, error compensation and CAD/CAM subsystems were also surveyed and presented in detail. It is believed that the machine can fulfill its original design purposes.
