【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 2, the surface grinder 1 is provided with an XY table 3 which is movable in the X-axis direction (the left-right direction in FIG. 2) and the Y-axis direction (the direction orthogonal to the paper surface in FIG. 2). A chuck 5 such as a magnet is provided on the XY table 3. The work W is placed on the chuck 5, and the work W is fixed by the operation of the chuck 5. A dresser 7 is provided on the left side of the XY table 3. Since the structure of the dresser 7 is already known, detailed description thereof will be omitted.

A grindstone head 11 having a rotatable grindstone 9 is provided above the XY table 3 so as to be movable up and down.

With the above configuration, the XY table 3 having the work W placed and fixed by the chuck 5 can be moved back and forth in the X-axis direction, and the grindstone head 11 having the rotatable grindstone 9 can be lowered. Thus, the surface of the work W is ground. Further, by sequentially moving the XY table 3 in the Y-axis direction, grinding is performed according to the width of the work W.

As shown in FIG. 1, the control device 13 for controlling the surface grinder 1 is provided with a CPU 15, which has a length and a width of the work W and a diameter of the grindstone 9. Input means 17 such as a keyboard for inputting data such as width and display means 19 such as CRT for displaying various data are connected.

The CPU 15 is connected to a drive unit 21 including an X-axis and Y-axis motor of the XY table 3, a rotation motor for rotating the grindstone 9, and a vertical movement motor for vertically moving the grindstone head 11. There is.

Further, the CPU 15 is connected to a storage means 23, a machining program creation / execution means 25, a changing means 27 and an updating means 29. For example, as shown in FIG. 3, the storage means 23 stores data of a plurality of grindstones 9, that is, data for each grindstone number. As the data of the grindstone 9, for example, data which creates a coordinate system such that (X, Y) = (0,0) when the grindstone 9 is at the reference position of the chuck 5 (for example, the right end point of the chuck 5), The data includes the diameter and width of the grindstone 9 and the starting position when the grindstone 9 is dressed.

The data for each grindstone number stored in the storage means 23 is fetched by the machining program creation / execution means 25 to create a machining program as shown in FIG. 4, for example. Then, the driving program is driven by the created machining program to execute the grinding process.

Further, the data of the grindstone 9 stored in the storage means 23 is displayed on the display means 19 in a list as shown in FIG. 5 so that it can be confirmed and changed. There is.

In FIG. 5, the coordinate system, the dressing start position, etc. are set by the data of the number for which the “in use” message is displayed. To change the grindstone number, move the cursor key C beside the grindstone number up and down and press the "use" key, which is one of the changing means 27, to change the "in use" message display. It Further, when the "diameter / width" key at the bottom of the display means 9 is pressed, a screen for registering the diameter and width of the grindstone 9 is displayed, and the diameter and width can be registered.

When the “coordinate system” key is pressed, the registration screen for the coordinate system of the grindstone 9 is displayed, and when the “dress position” key is pressed, the registration screen for the dress start position is displayed. When the grindstone 9 is first attached, the grindstone 9 is set on each registration screen.

With such a configuration, since data is stored in the storage means 23 for each grindstone number, a machining program is immediately created and executed according to the grindstone number to be used at present. Therefore, when the grindstone 9 is replaced, the setup time can be shortened and the grinding process can be started immediately, and the grindstone 9 can be managed by the number, which facilitates maintenance.

When dressing the grindstone 9 with the dresser 7, the dressing is carried out according to the flow chart shown in FIG. That is, in FIG. 6, it is determined in step S1 whether or not dressing is performed during processing, and when dressing is performed, dressing is performed in step S2. Then, in step S3, the starting position of dressing is updated by the updating means 29, and in step S4, the coordinate system of the grindstone 9 is updated by the updating means 29. Furthermore, the diameter of the grindstone 9 is updated by the updating means 29 in step S5, and the grindstone 9 is cut and ground in step S6.

When it is determined in step S1 that dressing is not performed during processing, the process proceeds to step S6, and the grindstone 9 is cut and ground.

As described above, after dressing the grindstone 9 during processing, the coordinate system of the grindstone 9, the start position of dressing, and the grindstone diameter are automatically updated, and the data is stored, so that any position can be stored. The dressing can be performed with, and the size of the work W can be correctly ground.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes.
