Abstract
In recent years, five-axis controlled machine tool attracts attention from the increase in the demand for the improvement of productivity. A square end mill is often used for rough cutting, because it has much removal rate. However, five-axis controlled machining with the square end mill is more difficult than in case of ball end mill. In this report, we will propose the tool path generation method for five-axis controlled machining with square end mill. By using this method, the position and the posture of end mill which were near the interference surface as much as possible were searched along the character line, and the tool path which moved the square end mill near the character line was generated. As the result of simulation, we confirmed the generated tool path was able to minimize the cutting remains near the character line.
