Papers by Keyword: Die-Set

Abstract: Die-Set is one of the Punching/Blanking die components. It includes lower and upper shoes, guide posts and guide bushes. The High demand of Die-Set in industry resulted in the supply of specified die set from many manufacturing companies. The standard components in the market cover only the small and medium die sizes. In many cases, the designers need to build their own die-sets especially in case of progressive die design and non-tradition die sizes. In this paper, a CAD system for building a Die-Set is discussed. This system is built using Visual Basic (VB) interfacing with AutoCAD. The system covers all Die-Sets sizes (small, medium). The proposed CAD system is prepared to work as a standalone or as a subroutine for a blanking die design CAD system. It saves time in Die-Set design operation from hours to minutes. This module is a part of a series of studies to automate the design of sheet metal working tools.

Abstract: 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.
