Abstract
This paper focuses drill-movement time. Drill moving time is not at all small when compared with cutting processing time. TSP was applied to determine the moving route of PWB holes arrangement. No one has attempted to quantify the effect of TSP. So, effect of applying TSP method is conformed by Fractal'index. Someone aimed at the improvement of the calculation time and accuracy of the TSP method to obtain the shortest route. However, considering the characteristic of PWB hole arrangement and feed control characteristic of machine tool the shortest route of geometrical problem TSP is not always the shortest moving time. So, feed control characteristic of machine tool is .applied to TSP method;. We researched a CAM system of PWB integrated the feed control characteristic of machine tool. However, the quality of PWB will be decreased in the section where the pitch between holes is extremely short. Then; it proposes the technique to prevent PWB being transformed by suppressing the highest temperature when processing it.
