5-axis controlled machining has a high degree of freedom, so we can get any tool attitude at each cutting point. On the other hand, the changes in tool posture may be redundancy, and cause the decrease in accuracy of machining surface. To solve this problem, in this study, 2-dimensional configuration space technique is applied to generate the tool path. If the interference surface of work piece is curved surface, There is no interference occur and the tool attitude change is optimal for the whole of machining surface. Through this technique, we can realize the optimization of the tool attitude change on the whole of machining surface. Finally, we verify the usefulness of the devised technique by machining simulation.
