First, the workpiece W is mounted on the table 17. Further, a plurality of through holes Wc are formed in advance on the side faces Wa and Wb of the workpiece W.

Then, after the conveyance device 15 is positioned so as to face the hole Wc below the workpiece W, the conveyance rod 15b is extended. Thereby, the CCD camera 31 and the laser range finder 32 are transported to the measurement position P1 from the retracted position P2.

At this time, in the analyzing device 19, the center and the inner diameter of the lower hole Wc are calculated based on the input image data.

Further, when the distance between the plurality of irradiation points on the side surface Wa of the workpiece W is measured by the laser range finder 32, the plurality of measurement distances of the measurement are input to the NC device 20 via the analyzing device 19. At this time, in the analyzing device 19, the inclination angle of the side surface Wa and the distance from the end surface of the lower hole Wc are calculated based on the plurality of input measurement distances. Further, in the case where the laser range finder 32 is used as described above, the distance measurement using the laser range finder 32 is performed at least twice.

Then, in the NC device 20, based on the center of the input lower hole Wc and the inner diameter, the inclination angle of the side surface Wa, and the distance from the end surface of the lower hole Wc, it is determined whether or not the workpiece W has a mounting failure and whether the workpiece W exists.

The distance between the end faces is corrected, and the movement of the correction tool T in the Y-axis direction and the Z-axis direction and the movement of the workpiece W in the X-axis direction are performed. Thereby, even if the workpiece W is obliquely attached to the table 17 or the workpiece W has a defective shape, the mounting position of the workpiece W can be corrected, and the hole Wc and the lower hole Wc of the workpiece W can be specifically processed.

Further, even if it is determined that the workpiece W has a cutting residue even after the correction of the movement of the tool T and the workpiece W, the machining of the machine tool 1 is stopped, and a warning for notifying the mounting failure or the shape of the workpiece W is started. Use an alert.

The workpiece determiner 30 in the device 15 is a laser range finder 32. Thereby, since it can be transported for each The device 15 specifies the set position, so that the photographing portion of the CCD camera 31 and the irradiation point of the laser range finder 32 can be set at separate positions.

Further, in the above-described embodiment, the machine tool for processing the workpiece W is a machine tool 1 including one column 11, as shown in Fig. 5, or in the thickness direction of the workpiece W attached to the table 17. To the machine tool with two columns 11 arranged.

In other words, by arranging the two columns 11 so as to sandwich the workpiece W in the thickness direction, the center and the inner diameter of the hole Wc under the opening of the side surface Wa are measured by the workpiece measuring device 30 attached to the conveying device 15 on the side surface Wa side. The inclination angle of the side surface Wa and the distance between the hole Wc and the end surface under the opening of the side surface Wa are measured by the workpiece measuring device 30 attached to the conveying device 15 on the side surface Wb side at the center of the hole Wc below the opening of the side surface Wb. And the inner diameter, the inclination angle of the side surface Wb, and the distance between the hole Wc and the end surface under the opening of the side surface Wb. Thereby, the center and the inner diameter of the lower hole Wc, the inclination angle of the side faces Wa, Wb, and the lower hole Wc can be simultaneously measured from both sides in the thickness direction of the workpiece W by the workpiece measuring device 30 attached to each of the conveying devices 15 facing each other. Since the distance from the end surface is separated, the workpiece W can be measured in a short time and with high precision.

Further, in the above-described embodiment, the column 11 is fixed, but it may be configured to move in the X-axis direction and the Z-axis direction.

Further, it is determined whether or not the workpiece W is installed by the above-described four measurement results of the workpiece measuring device 30. The defect and the shape are poor, and the workpiece W can be processed with high precision by controlling the movement of the tool T and the workpiece W based on the determination result.

Further, since the workpiece measuring device 30 can be transported between the measurement position P1 and the retracted position P2 by the transport device 15, the measurement position P1 can be made as close as possible to the workpiece W, so that the measurement accuracy of the workpiece measuring device 30 can be improved. On the other hand, since the retracted position P2 can be moved as far as possible from the workpiece W, it is possible to prevent damage or malfunction of the workpiece measuring device 30 caused by chips or cutting oil scattered by processing.

Further, the center and the inner diameter of the lower hole Wc, the inclination angle of the side faces Wa, Wb, and the lower hole Wc and the end face are simultaneously measured from the side of the side surface Wa side and the side surface Wb side of the workpiece W by the plurality of workpiece measuring devices 30.
