[Problem to be solved by the invention]

Since the conventional NG device equipped with an interactive ^P device was configured as described above, when the EIA machining program created by the AP side became long, the machining program storage memory (20b) of the NC section (20) ) may not be able to create data due to memory capacity limitations, or machining program storage memory (

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1, in which the same parts as in FIG. 3 are denoted by the same reference numerals.

In Fig. 1, the difference from the conventional one is the NC section (2
0) is a buffer (20g) that temporarily stores the machining program input from the AP section (21) during AP operation.
In addition, the AP section (21) has an AP section side sub-mode switching section (21d) that switches between the AP operation mode and the mode registered in the machining program storage memory. ) and NC department (20)
Switching between table mode and AP mode, and AP section (l
It also serves as mode switching for AP operation and machining program storage memory registration in 2), and also serves as the AP side sub-mode switching section (2 1 d) of the P section (l2) and the NC of the NC section (20).
The point is that a sub-mode switching operation section (21 (1)) that interlocks the side sub-mode switching section (20h) is provided.
1) is a CRT that displays the AP operation mode by the sub-mode switching operation section (21e).

Next, the operation will be explained. Generally, the NC operation modes include a tape operation mode, a memory operation mode, an MDI operation mode, and an AP operation mode. This mode change is performed by a mode changeover switch (23), but in order to reduce the number of hardware parts, the tape operation mode and the AP operation mode are made common, and the tape/AP mode is used.

By switching the mode changeover switch (23), the mode changeover unit (20d) inputs the EIA machining program to the tape buffer (20a), the machining program storage memory (
20b) or MDI memory (20c).

The submode switching operation section (21e) of the ^P section (21) switches the tape/AP operation mode between the tape mode and the AP mode, and the switching information here is transferred to the NG section (20
) is sent to the NC side sub-mode switching unit (20h),
Input from table reader (22) or AP buffer (2
0g) is input. At the same time, this switching information is also transmitted to the AP side sub-mode switching section (21) of the AP section (21).
In conjunction with d), it is also used to determine whether to output the EIA machining program to the AP buffer (20g) or register it in the machining program storage memory (20b). Further, this switching information is also sent to the CRT (11) to indicate to the operator which mode is selected and to prevent erroneous operations from occurring.

Next, the purpose of the AP buffer (20g) will be explained. AP

) operates in the background and foreground. Therefore, the AP buffer (20g) is
Even when the IA machining program is installed and the AP dialogue data is being analyzed, the machining program analysis can be input one block at a time without interruption, so that the NC machining is not affected by the dialogue data analysis time. That is, the AP section (21) transfers the EIA processing program to the AP buffer (20g) so that the buffer is always full.

Furthermore, an operational example of AP operation will be explained. First of all, ^
In order to perform the P operation, the mode of the mode changeover switch (23) is set to the tape AP operation mode. Next ^P section (21
) is set to ^P operation. With this operation, the CRT (25) has an AP
It will display that it is in driving mode.

Next, the keyboard (10) and CRT (11) in Figure 2
While interacting with the AP unit (2l) using the AP unit, dialogue data is created and the dialogue data is stored in the dialogue data storage unit (21a). Dialogue data is input from the dialogue data analysis unit (21a), coordinate value subtraction and processing conditions are automatically determined,
It is converted into an EI^ machining program by the EIA data conversion unit (21c), passes through the sub mode switching unit (21d), and is set to NO.
A plurality of blocks and the EIA machining program are transferred to the AP buffer (20g) of section (20) for the buffer capacity.

Then, the dialogue data analysis section (21d) and the EI^ data conversion section (21c) enter a waiting state until the AP buffer (20g) becomes empty.

Next, when the NC operation is started, AP buffer (20g)
One block of the EIA machining program is transferred to the table buffer (20a) through the NC side sub-mode switching section (20h). At this time, a free space is created in the AP buffer (20g), and in order to fill it, the dialogue data analysis part (2lb) of the AP part (21) and the EIA data conversion part (
The waiting state of 21c) is released, the EIA processing program is transferred to the AP buffer (20g) again, and the waiting state is returned. Next, the tape buffer (
The EIA machining program transferred to 20a) passes through the mode switching unit (20d) and is transferred to the machining program analysis unit (20e).
is input. The machining program analysis section (20e) is EI
The tool path and speed are calculated from the A machining program and output to the control section (20f). The control section (20f) performs pulse distribution, machine control, and servo control based on the tool path and speed, and outputs the results to the machine tool [(24). Then read the EIA processing program from the AP buffer (20g) and repeat the same process. As a result, the machine tool (24) is numerically controlled by the control unit (20f) to produce according to the AP compatible data.
AP online operation is possible using the image of EIA table operation.

Note that in the above embodiment, the submode switching operation section (21e
) is provided in the AP part (21), but the NC part (
20) or the mode changeover switch (23), similar effects can be obtained.

[Effects of the Invention] As described above, according to the present invention, by transferring the EIA processing program of the EIA data conversion section of the automatic blog reading control section to the tape buffer section of the numerical control section,
