Abstract

Progressive tool plays a vital role in sheet metal industries. It can perform various individual operations or combination of operations at two or more stations. In progressive tool design, strip layout design plays a key role. The design of strip layout should be in such a fashion that it can utilize more than 70% of total stock material. This paper describes the design of strip layout, actual cutting load required to perform the operations and based on this load calculation of press capacity and design of die element like thickness of die block, bottom bolster, top bolster and punch plate etc. The software used for modeling of die element is Creo 2.0 and for drafting of assembly drawing is AutoCAD 2016. ANSYS 17.2 is used to perform finite element analysis on blanking punch to ensure the working condition of tool within the limit.
