If-Then Rules for Selection the Die-Set for Sheet Metal Punching and Blanking Dies

Die-set is an essential tool accessory in sheet metal punching and blanking. The selection of the die-set represents an important activity in the die design operation. Time and money consumed in this operation could be saved by using an automated selection system for die-set components. This paper discusses an intelligent die-set selection system using the AutoCAD platform. The developed system is able to work as either standalone or connected with any die design CAD system by using the well-known AutoCAD programming tools. The proposed system is built using IF-THEN rules approach. The system code is developed using AutoCAD with Visual Basic. A data-base of Nasr Automotive Company (NASCO) for die-set was considered, from which suitable size of die-set was selected automatically. The proposed system could reduce the consumed time in the tool room department from hours to minutes and could reduce effort and cost as well.
