Computer Aided Design of Press Die : Standarization of Production and Blank Layout

An automatic drawing on the diesets of press dies was developed in the last year, which had two or four guide posts. In this report, the method of the automatic drawing was also developed on the blank-layout with many parametoric factors. This program was composed of 4 stages, drawing fundamental patterns, arranging them for X-axis direction and Y-axis direction, and setting the feed holes. There are provided 8 kinds of fundamental patterns as an example of standardization of many kinds of productions. The results obtained were summerized as follows. 1) Many kinds of blank-layout could be easily drawn using the fundamental patterns. 2) The shape of each pattern could be changed only to put the suitable values. 3) This program is divided into 4 stages, then a designer may confirm the results of each stage. 4) As these programs were named in organization, the designer could select them immediately.
