Next, after positioning the conveying apparatus 15 so that the lower hole Wc of the workpiece | work W may be opposed, the conveyance rod 15b is extended. Thereby, the CCD camera 31 and the laser measuring device 32 are conveyed from the retracted position P2 to the measurement position P1.

And when the lower hole Wc of the workpiece | work W is image | photographed with the CCD camera 31, the image of the image | photographed lower hole Wc is converted into image data, and the NC apparatus ( 20) is entered. At this time, the analysis device 19 calculates the center and the inner diameter of the lower hole Wc based on the input image data.

In addition, when the distance to the some irradiation point on the side surface Wa of the workpiece | work W is measured by the laser measuring instrument 32, the measured some measurement distance will be an NC apparatus through the analyzer 19. It is input to 20. At this time, in the analyzer 19, the inclination angle of the side surface Wa and the distance to the end surface of the lower hole Wc are computed based on the input several measured distance. In this way, when the laser measuring instrument 32 is used, distance measurement by the laser measuring instrument 32 is performed at least twice.

Next, in the NC device 20, the workpiece W is based on the input center and inner diameter of the lower hole Wc, the inclination angle of the side surface Wa, and the distance to the end surface of the lower hole Wc. It is determined whether there is a mounting failure and whether there is a shape failure in the work W. FIG.

At this time, when it is determined that there is no mounting failure in the workpiece W, and when it is determined that the workpiece W is not defective in shape, the tool T is moved in the Y-axis direction and the Z-axis direction based on a preset machining condition. By moving the workpiece W in the X axis direction, predetermined machining is performed on the end faces of the lower hole Wc and the lower hole Wc of the workpiece W. As shown in FIG.

On the other hand, when it is determined that the workpiece W has a defective mounting or when it is determined that the workpiece W has a defective shape, the center and inner diameter of the lower hole Wc, the inclination angle of the side surface Wa, and the lower hole Based on the distance to the end surface of (Wc), the movement of the tool T in the Y-axis direction and the Z-axis direction, and the movement of the workpiece | work W in the X-axis direction are correct | amended. Thereby, even if the workpiece | work W is inclined and mounted in the table 17, or there is a shape defect in the workpiece | work W, the installation position of the workpiece | work W will be correct | amended and the Predetermined processing is performed with respect to the lower hole Wc and the lower hole Wc.

And even if the movement of the tool T and the workpiece W is corrected, when it is determined that an uncut portion occurs in the workpiece W, the machining by the machine tool 1 is stopped, and the workpiece W is Warning alarm is started to inform the mounting failure or shape failure.

In addition, in this embodiment mentioned above, although one conveyance apparatus 15 is provided in the side surface of the saddle 12, you may provide a some conveyance apparatus 15.

As shown in FIG. Thereby, since an installation position can be specified for every conveying apparatus 15, the imaging | photography part of the CCD camera 31 and the irradiation point of the laser measuring device 32 can be set in a separate position.

In addition, in this embodiment mentioned above, although the machine tool 1 provided with one column 11 is employ | adopted as a machine tool which processes the workpiece | work W, as shown in FIG. In the thickness direction of the workpiece | work W which attached the column 11 to the table 17, you may be set as the machine tool which opposes.

That is, by arrange | positioning the two columns 11 so that the workpiece | work W may be interposed in the thickness direction, by the workpiece | work measuring device 30 attached to the conveying apparatus 15 of the side Wa side, , While measuring the center and inner diameter of the lower hole Wc opened to the side Wa, the inclination angle of the side Wa, the distance to the end surface of the lower hole Wc opened to the side Wa, The center and inner diameter of the lower side hole Wc opened to the side surface Wb by the workpiece | work measuring device 30 attached to the conveying apparatus 15 of the (Wb) side, the inclination angle of the side surface Wb, and the side surface Wb. The distance to the end surface of the lower hole Wc opened by the edge is measured. Thereby, by the workpiece measuring device 30 attached to each of the conveying apparatus 15 which opposes, from the thickness direction both sides of the workpiece | work W, the center and inner diameter of the lower side hole Wc, and the side surface Wa, Wb of Since the inclination angle and the distance to the end face of the lower hole Wc can be measured simultaneously, the workpiece W can be measured in a short time and with high accuracy.

In addition, the conveying apparatus 15 enables the workpiece measuring device 30 to be transported between the measuring position P1 and the retracted position P2 so that the measuring position P1 is as close to the workpiece W as possible. Since it is possible to do this, the measurement accuracy of the workpiece measuring device 30 can be improved. On the other hand, since the retracted position P2 can be made as far as possible from the workpiece W, it is possible to prevent breakage or failure of the workpiece measuring device 30 due to cutting chips and cutting oil scattered by processing.

In addition, the plurality of workpiece measuring devices 30 incline the center and the inner diameter of the lower hole Wc and the side surfaces Wa and Wb from both directions on the side surface Wa side and the side surface Wb side of the workpiece W.
