Abstract
Based on customer requirements of components, design engineers create the necessary tooling using CAD to produce the exact part desired by the customer. A software package using CARL is developed to help the design engineer to create the drawings of Pinch off Punch and Pinch off for both rectangular/square and round punches. A variety of hole patterns for the punches are automatically created through the software, along with a possibility of selecting one of the standard patterns automatically for a drawing. The drawings are created such that the dimensions and the notes are automatically generated with the input of the punch length, height, width and other variables.
The Pinch off Punch and Pinch off are used to achieve high production. The required shape of the box or shell is formed over the pinch off Punch and is pinched to correct size with the Pinch off. The basic operation involved is drawing. Report presents detailed discussion on Pinching and Pinch trimming along with the discussion on drawing.
A brief outline of CADL, CADKEY Advanced Design Language, is presented to emphasize the capability of CADL to develop user interface from within the CADKEY environment, to automatically generate drawings, and to customize CADKEY operations.
