A Heuristic Algorithm for Optimum Layout of Metal Stamping Blanks

Layout of metal stamping blank marks the first stage of a tool and die design. Traditionally, this is dependent on the skill of the craftsman who may spend many hours in achieving the final solution. In this paper, a heuristic algorithm is developed on a computer with user-friendly dialogues. The algorithm generates an optimum layout considering such factors as minimum material wastage, correct bridge width and grain orientation. In addition, it provides such information as recommendation on stock purchase policy, economic justification for a single or multiple-station operation and alignment of centre of pressure with press centre. Computer-generated solution compares very favourably with laborious trial-and-error industrial practices.
