Abstract
The processing material's shape data is obtained by measuring the three-dimensional shape of the processing material W by the three-dimensional measuring device 45, the machine's shape data defining the three-dimensional shape of the machine side including the main shaft head provided with the processing tool and the tool holder attached thereto is obtained, and whether the coordinate position of said processing material given by said processing material's shape data is in the space to be occupied by the machine given by said machine's shape data or not is determined at the relative movement position between the main shaft head (43) and the work table (35) by the execution of the processing program by the arithmetic processing by means of an arithmetic processing means, and when the coordinate position of the processing material W is in the space to be occupied by the machine, it is determined that the processing material W and the machine interfere with each other.
