Abstract

PURPOSE:To easily and quickly produce a working program by displaying the working program with characters and pictures on a CRT screen. CONSTITUTION:Plural fundamental programs corresponding to preliminarily determined working fundamental patterns are preliminarily stored in a storage device. Plural working fundamental patterns corresponding to these stored fundamental programs are displayed as pictures on a screen 16a of a CRT 16. The working fundamental pattern resembling a working pattern is selected from these pictures to retrieve a specific fundamental program. When an actual working program is produced from this retrieved fundamental program, items to inform an operator of required working data to be inputted are displayed on the screen 16a by characters. Working data is inputted based on this display to produce the working program. Thus, the working program is easily and quickly produced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interactive numerical control method, and more particularly to an interactive numerical control method in which a predetermined basic program is edited to create a machining program for use in actual machining.

FIG. 1 shows a block diagram of a device implementing a conventional interactive numerical control method, and 10 is a group of process lamps that display the procedure for inputting a machining program.

A data key 12 is used to search for a desired pattern from pre-stored basic patterns and to input data into the searched basic pattern.

14 is a data display device that displays input data.

An example of program creation for turning will be described below with reference to FIG. As a preparation before starting the actual operation, some basic patterns necessary for turning are drawn. 9Drawn basic pattern f: Coded using a special programming language, and the basic pattern is memorized in advance using this code. Stored in the device.

Create a collection of drawings showing the relationship between memory numbers and basic patterns when stored.

Next, when a processing drawing is given, first, the processing drawing is compared with the above-mentioned drawing collection to find a basic pattern similar to the processing drawing from among the 9 drawing collections, and the memory number corresponding to that basic pattern and the unique pattern of that basic pattern are stored. Coordinates or dimensions on the processing drawing corresponding to the program points, processing conditions, etc. are entered on the process sheet. Once the process sheet is completed,
Enter data from the operation board exactly as written on the process sheet. In FIG. 1, the process lamp group 10 is configured so that its lighting position shifts from left to right on the page each time the write key 12a of the data key 12 is pressed, and in the initial state, the position of the basic program search tOa is It's lit. First, key in the memory number of the desired basic pattern using the data key 12, and press the write key 12ai to search for the basic pattern, and at the same time, process lamp group 1
0 is P, and the position of coordinate 10b lights up. Next, use the data key 12 to enter the coordinates ft on the X and Z axes corresponding to the program point P of the basic pattern.

When the write key 12a is pressed, P and the coordinates are set.

At the same time, the lighting position of the process lamp group 100 moves to the P2 coordinate 10c. Below, at the same time, the lighting position 10d of the process lamp group 10
・108 ・10f ・Creation of the machining program is completed by keying in the data corresponding to 10g. The keyed-in data is displayed on the display surface of the data display 14 each time. That is, the data keyed in for steps 10a to 10d are displayed on the display surfaces 14a and 14b of the data display 14, and also on the steps fOe, 10f, and 1.
The data entered regarding 0g is displayed on the display screen 14c.1
Displayed on 4d and 14g. 14f is a storage number display surface.

Conventional numerical control methods create machining programs as described above, so a collection of basic pattern drawings and a process sheet are required for key-in, and the data displayed on the data display is cleared every time the write key is pressed. This has the disadvantage that it takes a long time to complete the machining program.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide interactive numerical control that allows machining programs to be created easily and quickly without using basic pattern drawing collections, process sheets, etc. The purpose is to provide a method.

In order to achieve the above object, the present invention stores a plurality of basic programs corresponding to a predetermined basic machining pattern in a t-S crimping storage device, and performs machining from among the stored plurality of basic programs. Search for a specific basic program similar to the pattern, display the searched basic program as text and images on the screen of the cathode ray tube display device, and edit the processing data of the displayed basic program by key input to create the above basic program. is converted into a machining program, and this machining program is displayed as characters and images on the screen of the cathode ray tube display device.

A preferred embodiment of the present invention will be described below based on one drawing. FIG. 2 shows a configuration diagram of an apparatus for carrying out the method of the present invention, in which 16 is a cathode ray tube display apparatus (hereinafter referred to as CRT).
), 18 is a cursor key for shifting the position of the cursor appearing on the CRT screen 16a, and 20 is a CR
This is a page key for selecting a page on the T screen. In FIG. 2, the same parts as in FIG. 1 are given the same reference numerals, and their explanation will be omitted.

The basic program consists of a basic pattern and a data table in which information such as X-axis and Y-axis coordinate points for drawing the basic pattern is entered, as will be described later.

Below, nine operating methods of the present invention will be explained. Processing drawing (
(not shown) is given, first operate the page key 2G to select the basic pattern list stored in the storage device (not shown), and display the image of this basic pattern list on the CRT screen 16a as shown in FIG. to be displayed. A basic pattern similar to the processing drawing is found from among the displayed images, the memory number corresponding to this basic pattern is keyed in using the data key 12, and the write key 12 & is pressed.

As shown in FIG. 4, the basic pattern 100 and data table 102 are displayed on the CRT screen 161k.

That is, a specific basic program is searched.

Next, while looking at the processing drawing, enter the coordinates of each program point P - P4 in the data table 102 using the data key 12.
and cursor key 18 to key in sequentially and write 1?
-12a, the image on the CRT screen 16a displays the machining pattern 110 and data table 112 as shown in FIG.
The image changes to Then, it is checked whether the machining pattern 11G appearing on the CRT screen matches the machining drawing, and if they match, the creation of the machining program is completed.

If the machining drawing is composed of a combination of several basic patterns, a machining program can be created in the same manner as above by overlapping two or more basic patterns 102 as shown in FIG. can.

The uninvented method can also be operated as follows.

il+ Coordinate axes of program coordinate points to be edited in the retrieved basic program, for example addresses X, Z, C.

Only R is displayed on the 1cRT screen, and the coordinate values are edited by key input.

(2) Position i of the program coordinate point to be edited in the searched basic program, mark 9 on the image on the CRT screen, for example.
Mark with numbers etc. to indicate the order of editing.

131c Stretch or contract the image displayed on the RT screen.

As described above, in the numerical control method of the present invention, the basic pattern and the edited machining pattern are displayed on the lcR'r screen, so that the basic pattern and the edited machining pattern can be easily compared with the machining drawing. Further, since a collection of drawings of basic patterns and process sheets are not required, in combination with the above points, there is an effect that machining programs can be created easily and quickly.
