This paper focuses on shortening drill-movement time in an X-Y plane. Traveling Salesman Problem (TSP) has been applied to determine a moving route of Printed Wiring Board (PWB) hole arrangements. Thus, some papers dealt with shortening the calculating time and increasing the accuracy of the TSP method to obtain the shortest route in geometrical problems. However, considering both the characteristics of PWB hole arrangements and the feed-control characteristics of machine tools, the shortest route for geometrical problems by TSP is not always in agreement with that of the moving time problem. Therefore, we propose a CAM system for PWB drilling considering the feed-control characteristics of machine tools using a new TSP method to obtain the shortest moving time.
