A study on the CAD/CAM system of transfer die for deep drawing process

An approach to CAD/CAM system based on the knowledge based system is described. The CAD system is written in AutoLISP on the environment of AutoCAD software. The CAM system is written in CTK customer language on the environment of SmartCAM software. The input to the CAD system is a process planning data of a deep drawing product and the output from the CAD system are the die design drawings for transfer press. The input to CAM system are modeling data of transfer die design and die outputs from the CAM system are NC data which can apply to actual site. In this study, the technological knowledge of process planning, die design, and die manufacturing in deep drawing process is formulated by the interview of experts in the field. In addition, the new concept of the definitions for the alphanumeric terms is adapted. An application of this system provides effective aids to the designer and the manufacturer of the transfer press die in the field.
