In this application, the customer required an elongated D lancing punch. Lancing is defined as a process where material is sheared and bent to make tabs, vents and louvers. During the process, there's no material removed, it is formed into the shape required. The customer requested a 13/32" x 1-19/32" tab to be generated. We machined a blend radius on the rectangle end of the die to prevent the material from shearing. The angle of the tab varies depending on the stroke of the punch.
