Multi-tasking machine tools are popular owing to properties such as high flexibility and productivity. It is essential for an operator to avoid collisions between the machine structure and workpieces as machine tools realize complicated motions. Thus, a machine simulator is widely used prior to machining operations to solve this problem. However, unexpected collisions often occur in a commercial machine simulator when the setup of a workpiece or a jig differs from the 3D models created in advance. Therefore, this study proposes a machine simulator that utilizes 3D models created by measuring the shape and position of the workpiece and jig on the machine tool. In a case in which the workpiece differs from the desired workpiece, it is necessary to determine a suitable position and orientation of the target shape based on the obtained objects to modify NC (Numerical Control) programs. In this study, a decision method of the position and orientation of target shape is devised such that it corresponds to actual objects obtained by on-machine measurement.
