The projector 6 and the personal computer 9 are mainly configured, and a display projected from the projector 6 is configured to be performed on the table 5 in the cutting machine 1.

  The cutting machine 1 includes a table 5 fixed to the floor, a machining head 2 that can move in the width direction and the vertical direction with respect to the table 5 and to which a cutting tool 3 (such as a cutting tool or a drill) is connected, The processing head 2 is disposed and a gate-shaped column 1a movable in the longitudinal direction of the table 5. The control head 4 and the column 1a are controlled by a control signal from the control panel 4 according to the processing shape. The workpiece W can be moved and a predetermined processing can be performed on the workpiece W. In addition, the processing machine to which this invention is applied is not limited to this cutting machine 1, It can place the workpiece | work W and can perform various processes.

  The personal computer 9 includes a personal computer main body 9 as setting means and a pair of displays 8 for displaying the contents set in the personal computer main body 9. The personal computer main body 9 is used for presetting the processing shape of the workpiece W (that is, the product shape) or the fixed position of the workpiece W. As shown in FIGS. 2 and 3, the control panel 4 or a separate storage medium is used. The machining data of the product such as CAD data is read from the above, and the contour Wa along the machining shape is displayed on the screen 8a of the display 8 based on the machining data.

  On the screen 8a, various fixing jigs are displayed as a display K. By selecting a desired fixing jig and dragging it within the contour line Wa with a mouse or the like, the fixing jig is disposed. Is arbitrarily set (see FIG. 3). At this time, considering the trajectory of the cutting tool or the like grasped from the processing data, it is possible to avoid interference with the cutting tool or the like and to set an appropriate fixing jig arrangement position that can be securely fixed during processing. . The settings on the screen 8a are recognized by the personal computer main body 9.

  The setting data set in the personal computer main body 9 as described above is converted into a predetermined format and then sent to the dual monitor board D and sent to the projector 6 via the pair of RGB distributors 10 and the RGB cables C. It is done. Then, a display based on the sent data (a display similar to that set on the screen 8a of the display 8) is projected by the projector 6 and displayed on the table 5 as shown in FIG.

  Here, a pair (two) of the projectors 6 are disposed above the table 5, and the projection areas A and B are combined to form one display (the contour L <b> 1 of the processing shape and the disposition position of the fixing jig). L2) is performed. Thereby, an operator can sequentially arrange a predetermined fixing jig at the fixing jig arrangement position L2, and it is easy to specify an appropriate fixing position of the workpiece W (an arrangement position L2 of the fixing jig). Can be done.

  In addition, the display projected by the projector 6 includes a mark H (for example, a cross-shaped mark) as correction means, and a similar mark 5a (see FIG. 5) is printed on the table 5 in advance. ing. If the projection adjustment (projection direction, focus adjustment, etc.) of the projector 6 is performed so that the direction and size of the projected mark H and the mark 5a printed in advance match, the display by the projector 6 on the table 5 is displayed. It is possible to correct the relative position or scale.

  For example, as shown in FIG. 6, the fixing jig disposed on the table 5 includes a suction pad 11a formed on the upper surface, a suction hole 11b formed substantially at the center of the suction pad 11a, and the suction hole. A suction hose 11c that communicates with 11b and is connected to a negative pressure generating means (not shown) is provided independently at an arbitrary position. After disposing the fixing jig 11 at the disposition position L2, when the negative pressure generating means is driven while placing the workpiece W on the fixing jig 11, air is sucked through the suction hole 11b. Thus, the suction pad 11a has a negative pressure. As a result, the workpiece W can be sucked and fixed on the table 5.

  Further, a fixing jig may be used in which a valve is provided in the suction hole 11b so that the valve can be opened and sucked when the workpiece W is placed on the suction pad 11a. Alternatively, a suction hole may be provided on the bottom surface side, and a fixing jig may be fixed on the table by suction.
