抄録

<p>In the field of machining, multi-tasking machine tools have been popular because of their high flexibility and productivity. Thus, it is indispensable for the operator of machine tools to avoid collisions among complex machine structure and workpieces. In order to solve this problem, machine simulator is widely used before machining operations. In a commercial machine simulator, however, unexpected collisions often occur when the actual setup of workpiece or jig differs from the 3D models prepared in advance. On the other hand, the authors propose a machine simulator utilizing 3D models created by measuring the shapes of workpiece and jig on the machine tool. In case the workpiece differs from the assumed one, it is required to determine the position and orientation of target shape based on the obtained objects for modification of NC programs. Thus, this paper deals with a decision method of suitable position and orientation of target shape according to complicated workpiece shape by taking into account machining efficiency.</p>
