A CAPP System for Nonlinear Process Plans

Abstract Non-linear process plans are process plans which comprise different manufacturing alternatives Such non-linear process plans increase the flexibility of scheduling activities and allow to remedy quickly to disturbances in the workshop They are represented by Petn nets The automatic generation of a non-linear process plan is realised m different steps: - the feature based workpiece description is transformed into a non-linear sequence of operation steps: - the resources capable to manufacture : he specified operation steps, are determined. - the non-linear sequence is converted into a non-linear process plan which is directly usable for scheduling The developed CAPP system has been rested ‘or hydraulic components
