In sheet metal part manufacturing, bending is most commonly used in order to obtain rigidity and to obtain a part of desired shape to perform a certain function. The importance of process planning automation is well understood, and recently some experimental CAPP systems for bending operations have been constructed. However, current CAPP systems lack the ability of simulating the sheet metal bending modification, so many kinds of process planning constraints are difficult to utilize. To solve this problem, a bending operation simulator is developed and incorporated in our new process planning system AMPS. This simulator manipulates the modification of the sheet metal part as the transformation of thin plate solid models which represent the geometrical shape of the sheet metal part. By using the simulation result effectively for evaluating the constraints, process planning of complicated sheet metal part is computerized.
