| description | PURPOSE:To make an accurate interference check in a short time corresponding to the complicate motion of a tool, etc., and a complicate shape at the time of machining by the numerically controlled machine tool. CONSTITUTION:A coordinate data conversion part 26 converts an operation position from a shape data registration part 21 and plural shape data differing in the number of constituent shape elements at positions to interfere with the operation position into shape data of a three-dimensional coordinate system from a check coordinate system registration part 22 which is characteristic to the machine tool. A projection data generation part 27 projects the converted shape data on three planes of the three-dimensional coordinate system. A projection data arithmetic part 28 decides whether or not the projection data of the respective planes overlap with one another. An interference detection part 29 decides that interference is caused when the projection data arithmetic part 28 decides the overlap and projection data based upon the same shape data overlap with one another on all the planes. |
