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.

Abstract: The article focus on the metamorphic layer of punching die, punch matrix and die components in WEDM on the surface, the formation of metamorphic layer, the impact of metamorphic layers, line cutting the microscopic mechanism of the formation of cracks, and many were in-depth study and the corresponding preventive measures. These measures will speed up punching die design and manufacturing technology development. The die manufacturing technology here discussed can be the modern manufacturing technology research development direction.

Abstract: The 3D design technology of the punching die of the automobile panel is discussed, and the basic thinking of the 3D die design based on UG surrounding is introduced. The parallel idea combined the 3D parameterized model with the 3D design of the die is presented. Every kind of resource library of the die design and its application are also introduced in this paper. Furthermore, the matters needing attention in the punching die design of the automobile panel are put forward in order to improve the efficiency and quality of the die design.
