Abstract:
This paper considers the problem of defining feasible sequences of machining operations in process planning by using precedence constraints as well as optimizing their machining time by applying the appropriate simulation technique. Precedence constraints are defined based on dimensional, geometric, technological and economic relationships. According to these relationships, precedence matrices for operation sequencing are created. Variants of process plans are obtained by generating processes that contain feasible groups of machining operations. Finally, the optimal process plan is generated by simulating the defined variants of process plans in the SolidCAM software with the machining time as an objective function.
