Abstract

PURPOSE:To correctly verify a punching die and to improve the productivity by constituting a verifying device of the display device displaying the locus of a die and the graphic of a product by reading them from a product data input/output device and data input/output device, the data processor and an operation signal input device. CONSTITUTION:A bit of numerical control information is read via a command tape reader 6 from a numerical control command tape by the operation signal of an input device 1, converted into the locus of a punch die by a processor 2 and displayed on an image display device 7. And when the locus 13, 14 of a punching die is displayed against the perforated information of graphic data, it is recognized that the numerical control information displaying the locus of the punching die is an error. The erroneous numerical control information and its figure data and the display information of the punch locus are thus outputted to a printout display device 8 and used for the information for correcting the numerical control information of the later stage.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a verification device for numerical control command information in preparing a numerical control command tape for a numerically controlled punch press.

[Conventional technology]

Conventionally, as a method to verify the numerical control command tape (command tape) created for numerical control of a numerically controlled punch press, the information on the command tape is restored and the coordinate values, machining pattern code, and mold used in the command information are restored. On the other hand, the coordinate values that the worker converted from the drawing information into numerical control information again,
The method used was to compare and verify the processing pattern code and the information on the mold used.

[Problem that the invention seeks to solve]

In the conventional method described above, it is necessary to convert the drawing information into numerical control information again, and therefore, a large number of man-hours are required to verify the discovery of errors in the command tape. Also, since the representation formats of drawing information and numerical control information are different,
When converting the numerical control information, it is necessary to rely on the knowledge of the operator about the numerical control information (there is a problem that processing begins without being able to discover errors, resulting in defective products).

An object of the present invention is to provide a verification device for numerical control command information that can be verified easily and quickly.

[Means for solving problems]

The verification device for numerical control command information of the present invention includes a data input/output device for inputting and outputting numerical control information, product external contour information, and internal hole information, and coordinates of the numerical control information read from this data input/output device. position.

A display device that displays the locus of the punch die based on machining pattern code, information on the die used, etc., and displays the product figure successively output from the data input/output device; The apparatus includes a processing device that performs processing, and an input device that is connected to the processing device and inputs an operation signal.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, the verification device includes input device 1. Processing device 2. It consists of a data input/output bag storage 32 and a display device 4. Also,
The data input/output device 3 includes a storage device 5 and a command tape reader 6, and the display device 4 includes a screen display device 7 and a printout display device 8.

The input device 1 sends operation signals to the processing device 2 to read numerical control information and graphic information from a data input/output device 3 such as a storage device 5 and a command tape reading device 6, and a screen display device such as a printout display device 8. An operation signal is given to output the display contents of 7.

The processing device 2 performs data input processing to read numerical control information and graphic information from the data input/output device 3, and data output processing to the screen display device 7 and printout display device 8 of the display device 4.

The storage device 5 stores graphic data having external contour information and hole information of the product to be verified.

The command tape reader 6 reads the numerical control command tape,
Extract as numerical control information.

The screen display device 7 displays the locus of the punch die converted from the graphic data and numerical control information.

The printout display device 8 prints out on paper the graphic display, numerical control information (NC code, information on the mold used), and punch locus display displayed on the screen display device 4.

Next, the operation of the verification apparatus having the above configuration will be explained based on the flowchart of FIG. 2 using an example of graphic data consisting of product external contour information and hole information shown in FIG.

First, graphical data to be verified is retrieved from the storage device 5 by an operation signal from the input device 1 and displayed on the screen display device 7. FIG. 3 shows the display state.

Next, the numerical control information (minimum operation unit) is read from the numerical control command tape to be verified via the command tape reading device 6 according to the operation signal of the human-powered device 1, and the numerical control information is punched by the processing device 2. Convert to type locus,
It is displayed on the screen display device 7.

As shown in Fig. 4, when the trajectory of the punch die 13.14 is displayed for the hole information 11°12 of the graphic data, it is confirmed that the numerical control information that displays the trajectory of the punch die is incorrect. Prove.

At that time, the numerical control information is displayed on the same display screen.
5, its mold dimensions 16, and numerical control information 17.

If the punch trajectory is correct, reading the numerical control information from the command tape and displaying the punch trajectory continues. As described above, if the display of the graphic data and the display of the punch locus are different, that is, if an error in the numerical control information is found, an operation signal is given from the input device 1, and the incorrect numerical control information and its graphic data are combined with the punch trajectory. The trajectory display information is output to a printout display device 8 and used as information for correcting numerical control information in subsequent processes.

FIG. 5 is a diagram in which all the numerical control information is displayed as a punch locus 18, and shows a state in which two errors have been discovered and the verification has ended.

In this embodiment, an example was shown in which the numerical control information to be verified is obtained from the command tape, but the present invention can also be incorporated into an automatic numerical control information creation device. For example, it is possible to temporarily store the numerical control information created by the automatic creation device in the storage device 5 of FIG. 1 without outputting it to the command tape, and use the stored information.

In other words, it is possible to verify numerical control information that may contain errors without outputting it to the command tape.

Furthermore, although this embodiment shows an example in which error information (numerical control information, etc.) discovered through verification work is printed out on paper, the present invention can also be incorporated into a numerical control information correction device. Possible 0 For example, it is possible to temporarily suspend the verification work of the present invention when an error is discovered, correct the erroneous part using the correction function of the correction device, and once the correction is completed, the verification work can be continued again.

〔Effect of the invention〕

As explained above, by using the numerical control information verification device of the present invention, verification work of numerical control information with a large amount of information can be done by simply comparing the graphic information displayed on the screen and the trajectory of the punch die. Errors can be easily discovered, and there is no need to convert the drawing information into numerical control information and compare again as in the past, so there is no need to discover errors and produce defective products, allowing for quick and accurate verification. Therefore, the productivity of creating and verifying numerical control information can be improved and costs can be reduced.
