Optimal Blank Nesting Using Simulated Annealing

摘要: Since the cost of high volume stamped parts is largely dependent on material usage, scrap minimization is a primary goal of the design process. Although many factors influence the scrap rate for a given stamping, one of the most critical is the actual nesting, or positioning, of the part blanks onto the metal strip or sheet stock. Blank nesting is often done by hand, resulting in inefficient nestings with high scrap rates. Greater material efficiency can be achieved by automating this process. We have developed an automated system based on …
