System of computer aided-design about blanking workpiece by analyzing its sheet blanking technology and calculating its blanking force is studied in this paper. Some ques- tions
such as seeking for optimum model of blanking work piece
analysis of blanking tech- nology
designing technological steps
describing parts information
etc.
are major dis- cussed. We draw up software which deal with the above-listed items for various sheet parts. This software can realize the whole design
