Abstract

PURPOSE:To enable a machining condition control data to be input to and output from a host computer, by providing a means, which interprets, executes and feeds back a machining condition control command transmitted from the host computer, in an NC unit. CONSTITUTION:A transmitting and receiving means 12 receives a SYN command, when it is transferred to an NC unit from a host computer 1, to be fed to an interpretation means 13, and a machine interprets the command as the DATA LINK START to be fed to an executing means 14, storing the command in a memory 15. The executing means 14, which reads the command from the memory 15 outputting an OK command, showing the DATA LINK ESTABLISH PERMISSION, to be transferred to the computer 1 through the transmitting and receiving means 12, enables the command to be given and accepted. Thereafter, when an OK command, showing a down load of machining condition control data, is fed out from the computer 1, an NC unit side, deciding the down load for whether it is possible or not, feeds out the OK command to the computer 1 when possible. The computer 1, feeding a % command showing a data transfer start, transfers the machining condition control data to the NC unit side.

The cross table (7) is connected to the servo motor (4).

According to (5), machining of a predetermined shape is performed by only moving lζ. The data required for wire electrical discharge machining, namely the applied voltage, the feeding speed and tension of the wire electrode Q0, the moving speed of the X-Y cross table (7), and other various machining condition control data are exchanged as follows (ζ First, the host computer (1) that stores the machining condition control data is placed in a state of waiting for output, and then b
e-sou f! (2) Issue a data output command to the host computer (1). As a result, the machining condition control data from the host computer (1) is changed to ΔCi! (2) is downloaded to the storage unit.

Then, by operating the ΔC device (2) and outputting the machining condition data stored in the NCC device 2), the wire electric discharge machining described above is performed.

By the way, as mentioned above, the host computer (1).

He outfit! (2) A system consisting of a wire electrical discharge machine (or other machine tool) is generally called an FA system, and in this system,
Group management (centralized management) is performed in which a host computer (1) manages a plurality of NO devices a. In this case, it is often installed in a central control room or the like, far away from the host combination (1) and (2).

[Problem that the invention seeks to solve]

Since the conventional wire electric discharge machining apparatus is configured as shown above, when inputting and outputting machining condition control data, the host computer (1) v>interview, 1'+1jif! (
2) Whenever you have something to do with lζ, say NO! (
In step 2), it was necessary to perform data input/output work.

However, this causes deterioration in work efficiency and also causes the host computer (1) to perform ΔC equipment f! There are some problems, such as the fact that it is practically difficult to manage (2).

The object of the present invention is to obtain a wire electrical discharge machining device that can input and output machining condition control data to and from the device.

[Another way to solve the problem]

The wire electrical discharge machining apparatus according to the present invention interprets a machining condition control command sent from a host computer (D), executes the command as necessary, and transmits the result to the host computer using a wire electrical discharge machining device. This is the only one installed in the Mi device that controls processing.

[Effect]

In this invention, processing condition control commands are exchanged between the host computer and the NO device, and the processing condition control data is automatically transferred from the host computer to the NO table device.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.
In the figure, @ is a transmitting/receiving means for exchanging machining condition control commands with the host computer (1), (to) is an interpreting means for interpreting the contents of the machining condition control commands sent from the transmitting/receiving means a2η), (b) is an execution means that executes the processing condition control command interpreted by this interpretation means and sends it to the transmitting/receiving means; Give and receive between. Note that each of the above is provided in the NO table device 2) and constitutes an automatic data transmitting/receiving device (2a).

Further, FIG. 2 shows an example of processing condition control commands exchanged between the host computer (1) and the data transmitter/receiver %1j (2a). In the figure, α0 is the %8YN' command that indicates the start of the data link and the interruption of processing, 0 is the # command at 110 that indicates the establishment of the data link, and (g) is the hc device fi from the host computer (1) η).
-ED-command indicating to download data to t(2)lζ, Ql indicates that NO table device 2) can accept the above-mentioned download.
K# command, eiO, (20 is the command to start data transfer)
and 1%' command indicating the end of data transfer, (2) is the # command at 10 that informs the host computer (1) that data reception has been completed, and L)08' command indicates a request to temporarily stop data transfer. @ is the '1)01' command, which indicates to temporarily stop and restart one data transfer, (c)
is the %~G' command that indicates that data cannot be transferred, and (to) is the '''(JL# command) that indicates the completion of error processing. (to) is the processing condition control data, and an example of its format is shown in This is shown in Figure 3.The arrows in Figure 2 indicate the direction of transfer.

By the way, the configuration of the wire electric discharge machining apparatus according to the present invention is the same as that of the conventional apparatus shown in FIG. 4, so a description thereof will be omitted.

Next, the operation 1i' will be explained using FIGS. 1 to 8. Host computer (1) η) et al-SYN #Command exchange is NO via communication line (3)! (2) Once transferred, the transmitting/receiving means sends it to the receiving and interpreting means (to). Interpretation means (to) are transferred 1'18YN・
The command 0f19 is interpreted as "data link start" and the execution means α is sent. At this time, it is interpreted and outputs a ``command exchange'' to 50, which indicates ``permission to establish an execution data link'', and this is transferred to the host computer (1) via the transmitting/receiving means U. With this, commands can be exchanged between the host computer (1) and h(3imt(2)).Then, the host computer (
1) When the %ED command (to) indicating download of machining condition control data from t>> is sent, hcC device 2)

At the same time, the 1%' command (1) indicating the start of data transfer is sent, and the processing condition control data (to), an example of the format of which is shown in Figure 3, is transferred to the N (3 device k (2) side). It turns out.

When all the data has been transferred, the host computers (1) and 2) send a 1%' command (20&) indicating the end of data transfer. Transferred 11 here and 10&'
The command (c) is sent. This completes the transfer of the machining condition control data (e).
When data reception is temporarily stopped due to circumstances on the C device 2) side, a ``''L)03# command is sent, and when it is restarted, a ``ue1'' command is sent.

In addition, when an error occurs on the host computer (1) px etc. data download -El) # command (To) is sent, an error occurs on the 0x0 declaration (2) side and the download cannot be accepted. The ``NGNG-'' command is sent to the host computer (1).When this error is cleared, the ``0&'' command (c) indicating the completion of a process is sent to the host computer (1), and the data is downloaded. becomes possible.

As mentioned above, an automatic data transmitting/receiving device k is provided in the NOC device 2) and consists of a transmitting/receiving means @, an interpreting means (to), an execution means α and memories α9 and η). (By exchanging machining condition control commands between the host computer (1) and the host computer (1), the host computer (1) can directly control the various machining processes required for wire electrical discharge machining to the C device (2). This makes it possible to input and output condition control data.
