Abstract

PURPOSE:To surely and quickly edit the numerical control NC data by inputting the display position of the original data decided optionally to display the original data at this display position and showing the corresponding relation between the display original data and its corresponding graphic. CONSTITUTION:A graphic display part 4 displays the NC data stored in a stor age part 2 on a CRT 5 in the form of a graphic. An operator inputs a position A of a point or a line of the displayed graphic via a locator 6. A data identify ing part 7 searches the original data corresponding to the position A out of the part 2. When the original data is obtained, the operator inputs a display position B of the original data on the CRT 5 via the locator 6. A straight line display part 10 displays the original data given from the part 7 at the position B and at the same time displays a straight line connecting both positions A and B. In such a way, the NC data can be easily edited.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a numerical control (hereinafter referred to as NC) data editing device using a graphic editing method.

(Prior Art) As a conventional NC data editing device, a screen editor method using a character display has been the mainstream.

In this method, as shown in FIG. 4, NC data is displayed as characters (alphabets and numbers) on a display device, and the characters at the position indicated by a cursor operated by an operator are targeted for editing. However, the number of characters that can be displayed on one screen is limited to about 1,000, and the operator has to imagine the actual tool path from the displayed character string, resulting in larger and more complicated N.
It has become difficult to deal with C data. Therefore,
NC data m collection using a graphic editing method that displays NC data as a figure using a graphic display, and also uses an input device such as a locator to specify points or lines on the displayed figure and performs desired processing. The device was put into practical use.

FIG. 7 is a block diagram showing an example of a conventional NC data editing device using the above-mentioned graphic editing method, in which NC data is stored in a storage unit 2 via an input unit 1 and outputted via an output unit 3. It has become so. The NC data stored in the storage unit 2 is displayed as a figure on the CBr4 via the figure display unit 4, and the original data ((x, 'y, z) coordinate values of the point or line on the C1ITS specified by the locator 6 , sequence number, etc.) are identified by the data identification section 7 and displayed on the CBr 4 via the data display section 8.

In such a configuration, an example of its operation will be explained with reference to the flowchart of FIG. 8. The graphic display unit 4 displays the NC data stored in the storage unit 2 as a graphic on the CBr 4 (step Sl). The operator inputs the position of the point or line of the figure displayed on the CIIT 5 using the locator 6 (step S2). The data identification unit 7 searches the storage unit 2 for original data corresponding to the position of the point or line of the input figure (step S3), and checks the presence or absence of the original data (
Step S4). If there is no original data, step S2
Returning to step S5, the above-described operation is repeated, and if the original data exists, it is displayed at the display position of the original data on the CRTS via the original data display section 8 (step S5). The operator checks whether or not the process is completed in step S6).
If the processing has not been completed, the process returns to step S2 and the above-described operations are repeated, and if the processing has been completed, all operations are completed.

(Problem to be Solved by the Invention) When displaying figures and original data on the above-mentioned C[IT], for example, as shown in FIG. Ok,
There is a method of displaying figures and original data in each area. However, since the original data display area has a limited space, there is a drawback that a large amount of original data cannot be displayed at once. Therefore, as shown in FIG. 6, there is a method of displaying as much of the original data as possible in the graphic display area and displaying the remaining original data by sequential scrolling. However, there is a drawback that the figure and the original data may overlap, making the screen difficult to see. In addition, the operator had to remember the correspondence between the figures and the original data, which placed a heavy burden on the operator.

The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to enable an operator to display a large amount of original data in an easy-to-read manner, and to easily identify the correspondence between figures and original data. An object of the present invention is to provide an NC data editing device that can recognize NC data.

(Means for Solving the Problems) The present invention relates to an NC data editing device having a function of displaying input NC data as a figure and displaying original data corresponding to the figure. The above purpose is to input an arbitrarily determined display position of the source data, display the source data at the input display position, and display the correspondence between the displayed source data and the shape corresponding to this source data. This is achieved by providing means to do so.

(Function) In the NC data editing device of the present invention, the operator determines the position to display the original data while looking at the screen.
It becomes possible to display the original data at a position near the figure corresponding to the original data without overlapping the figure. moreover,
Since a straight line connecting the original data and the figure corresponding to the original data is displayed, the operator can immediately recognize the correspondence between them.

(Embodiment) FIG. 1 is a block diagram showing an example of the N(: data editing device) of the present invention in correspondence with FIG. In the data editing device, the display position of the original data specified by the locator 6 is input to the linear display unit 1O via the position input unit 9, and the original data from the data identification unit 7 is displayed on the CBr 5. The straight line connecting the above original data and the point or line of the figure corresponding to this original data is displayed at the CB position.
It is now displayed on r4.

In such a configuration, an example of its operation will be explained with reference to the flowchart of FIG. 2. The graphic display unit 4 displays the NC data stored in the storage unit 2 as a graphic in The position of the point or line of the figure displayed on the CIIT 5 (referred to as position A) is input using the locator 6 (step 512).The data identification unit 7 stores the original data corresponding to the manually input position A in the storage unit. Step 513) and confirm the presence or absence of the original data (Step 514). If there is no original data, return to step S12 and repeat the above operation, and if there is original data, the operator inputs the display position of the original data in CIIT 5 (position B) using locator 6 (step 515). . The straight line display unit 1O displays the original data from the data identification unit 7IJ) at position B, and also displays a straight line connecting position A and position B (steps 516 and 517). The operator checks whether the processing is completed (step 518), and if the processing is not completed, returns to step 512 and repeats the above-mentioned operation.
When the processing is finished, all operations are finished.

FIG. 3 is a diagram showing a display example of the NC data editing device of the present invention. In this way, it is possible to display the original data in a position that does not match the figure, and it is also possible to display the correspondence between the original data and the figure. It becomes possible to make it explicit.

(Effects of the Invention) As described above, according to the NC data editing device of the present invention, the operator can arbitrarily decide the number and display position of original data, and the correspondence between the displayed original data and figures. Since it is possible to easily recognize the NC data, it is possible to edit the NC data reliably and in a short time.
