Abstract

As the industrial era progressed, the need for mass production is more sensed. Progressive die is widely used for mass production of sheet metal components due to its high productivity, high precision and relatively economic cost in terms of per piece of product. Progressive dies perform a series of fundamental cutting and forming operations typically on continuous sheet metal strip, or coil, stock. These operations are performed simultaneously at two or more stations during each press stroke as the strip progresses through the die to produce a part. Design of progressive die is a complex and highly specialized procedure, so designer progressive die must have a high level of knowledge on the part that can only be achieved through years of practical experience.

Checking the design features of sheet metal parts, design of strip-layout, selection of die components, selection of materials for die components; and modelling of die components and die assembly are major activities for designing a progressive die. The traditional methods of carrying out these tasks require expertise and are largely manual and therefore tedious, time consuming and error-prone. The quality of die design depends to a large extent on the designer’s skill, experience and knowledge. This research attempts to study and priority the designing stages of progressive die by DFSS methodology (IDOV model). By focusing on the important stages, we can reduce the cost, the time of delivery and increase the quality and obtain the success factors.
