Abstract:

This report describes a method and a system for automatic generation of multi-technology process-outlines. A process outline is a sequence of operations leading from the raw workpiece to the required finished part. The method is applied to axisymmetric parts produced by a set of deep-drawing and machining processes. The method, the plan synthesis tactics and the forms of representations are based on the study and evaluation of the technological knowledge. The input is a CAD representation of the required finished part and the output is the highest priority process outline to manufacture the part. The process plan is developed, backwards, in two steps. In the first one a preform is designed and in the second a process plan to manufacture it is generated.
