Abstract

PURPOSE:To visually confirm a copying area by graphically displaying the whole copying areas corresponding to the copying command which is commanded by a copying program, on a CRT image screen. CONSTITUTION:A copying mode command analyzing part 3 reads the data of a copying mode MD, a copying parameter P, and a copying limit L corresponding to the commands of a copying mode MD, a copying parameter P, and a copying limit L respectively memory parts 40 to 42 and sends these data to a graphic display control part 5, to make a CRT display device 50 display these data, while also sending these data to an OR gate circuit 6. An AND gate circuit 7 receives the output signal of the OR gate circuit 6 at all times. When an operator confirms a copying area displayed on a CRT image screen and turns on a copying operation executing signal SS, command of copying operation is given to a copying device 8.

2. Description of the Related Art Tracing control devices that use a program to perform a plurality of tracing processes are becoming widely used.

However, in the past, this copying program was written using numerical data and symbols, and it was difficult for anyone other than the program creator to understand which part of the model was to be copied in the copying area for the copying process instructed by this program. Furthermore, even the program creator cannot easily and reliably confirm the area 70c to be copied, as shown in FIG. 7(C).
It is sufficient if the programmed copying area Tic matches, but as shown in FIGS.
tracing area 71a programmed for a, 70b;
71b do not match, errors such as uncopied areas 72a and 72b and incorrect copying area 73b will occur, and these mistakes cannot be confirmed until the actual copying operation is performed, and machining may not be performed according to the model shape, or machining may be interrupted during machining. The disadvantage is that the program must be stopped and corrected at a point, which not only takes a lot of time for machining, but also places a heavy burden on the operator.

(Object of the Invention) The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to display the copying area commanded in the copying program on the CR7 screen in a copying control device prior to copying operation. The object of the present invention is to provide a method for confirming the copying area, in which the copying area can be confirmed by visually checking the display.

(Summary of the Invention) The present invention relates to a method for confirming a copying area commanded in a copying program input to a copying control device. This is a copying area confirmation method in which the entire copying area corresponding to the copying command given in the above is graphically displayed on the CR7 screen and visually confirmed.

(Embodiment of the Invention) FIG. 1 is a block diagram showing one means for carrying out the invention, in which a copying program analysis/instruction section 2 is stored in a copying program storage section l as shown in FIG. It reads the copying program of the machine tool that performs the copying process, analyzes the data words commanded to this copying program, and outputs a copying selection command ST such as "TBSC" shown in the same figure. "TAPRC Approach Directive)',
It is divided into other commands SO such as “TTRG (copying start command)”, and the copying mode command analysis unit 3 and OR
A command is given to the gate circuit 6. The copying mode command analysis section 3 receives the copying selection command ST and selects the TBS shown in the figure.

When the copying operation execution signal SS is turned ON, the copying device 228 is commanded to perform copying operation. As is well known, the copying device 8 converts the displacement of the tip (stylus) of the tracer 80 in contact with the surface of the model 81 into an analog voltage, and converts it into an analog voltage.
The tracing speed calculation unit 82 receives this analog voltage signal and keeps the displacement amount of the tracer tip 80 constant in response to the scanning command corresponding to each scanning mode commanded from the tracing program analysis unit. While controlling the movement of the drive unit 83 so as to perform machining on a workpiece (not shown) in the same shape as the shape in the copying area instructed for this model.

The present invention will be described in detail below with reference to a flowchart shown in FIG. 2 showing the operation of the scanning area confirmation method of the present invention.

Before starting the copying device to perform copying operation, in order to check the copying area commanded by the copying program,
First, make sure that the copying operation execution signal SS is turned OFF (step S1).On the other hand, if you want to execute the copying operation immediately, such as when copying a model whose copying area has already been confirmed, step 5. If the signal SS is kept ON (step S2), the copying operation will be executed as is.

In step St, when it is confirmed that the signal SS is in the OFF state, the copying program analysis skewer command section reads a copying program as shown in FIG. 4 from the copying program storage section 1 block by block (step S3).
, to judge whether this block is a copying selection command or not (Step S4), as shown in parts A, B, and 0 of the same figure, "T
When the selection command of "ESC" is read, the copying mode storage section 40.
The corresponding data is read from the copying parameter storage section 41 and the copying limit storage section 42, and the graphic display control section 5
The copying area commanded by the copying program is displayed on the screen of the CRT display device 50 via (step S5), and if the copying program continues (step S6), the process returns to step S3. Go back and repeat the above operation for the next block, and display all the copying areas commanded during the copying program on the CR7 screen. Here, in the copying program shown in FIG. 4, the copying area commanded in section A is AA shown in FIG. 5, and similarly the copying regions commanded in sections B and C in FIG. BB and CC shown in FIG. 5, and an example of displaying all the copying areas instructed to the copying program in this way on the CR7 screen-L is shown in FIG. The entire tracing area 501 shown in FIG. 5 displays the contents of a function key (not shown) used for data input and correction.

The operator visually checks the copying area 500 thus displayed on the CR7 screen (Step S7), and checks whether the copying area in which this copying operation is to be executed and this screen are different as shown in FIG. 7 above. (Step S8
), copying program, copying parameter P, and copying limit L using an input means such as a YEAR board (not shown).
etc., in step Sθ), and return to step S1 to confirm the tracing area as described above.

Then, the copying area confirmed as above is “OK”.
If so, return to the first command of this copying program (step 5IO), , 1: Turn on the copying operation execution signal SS.
(Step 5ll) to execute the copying operation (Step 512), and end the copying operation in which the copying area has been confirmed by the copying area confirmation method according to the present invention.

(Effect of the invention) As described above, according to the scanning area confirmation method of this invention,
Prior to the actual copying operation in the copying device, the copying area commanded by the copying program is displayed graphically on the CR7 screen, so that it can be easily and reliably confirmed in a short time, and any errors can be detected. The corrected results are also confirmed as ``double series'', so machining errors during profiling operation, especially when multiple profiling processes are performed for one workpiece, are hindered, resulting in a reduction in the amount of time required for profiling machining. This has the effect of shortening and reducing time and costs.
