Özet

This paper presents an optimised process planning system for rotational parts. The model of a part is drawn by using a CAD module prepared for this purpose. After the feature recognition module, machining operations are determined and the cutting tools are selected by using the knowledge base and machining topology. An optimum sequence of operations is found by minimising the number of tool changes and tool travelling distance to decrease the cost per operation. The optimum cutting conditions are determined and stored in a CAD/CAM data base, accordingly. The part programs are then automatically generated in standard ISO codes on the basis of specific CNC lathe controllers. The generated part programs as well as tool paths can also be verified by graphical simulation prior to actual machining. The system is intelligent and requires little manual intervention. It is implemented with C + + on a personal computer.
