Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an interactive automatic programming device for creating NC tapes for numerically controlled (NC) machine tools and the like.

(Prior art) In automatic programming for creating normal NC tapes, tool paths and other machining conditions are entered into NC tapes based on design drawings using an electronic computer. In order to shorten the time it takes to complete a program and reduce program errors, various automatic interactive programming devices having a display function, such as a CRT, have been developed.

In the NC statement generation process using a conventional interactive automatic programming device, system data corresponding to the type of machine tool is read from a cassette magnetic tape or the like, and various data files stored at that time are utilized. In other words, the operator inputs the part program while referring to the file and displays various interactive data to be read and written on the CRT, executes arithmetic processing each time a line is input by the programming device, and then executes the NC program. It is stored in memory as a program.

(Problems to be Solved by the Invention) In the input method of such conventional interactive automatic programming devices, display screens for the various data files mentioned above are provided in addition to the dedicated screen for input, and programming In the process, the operator calls up the data file he or she needs by, for example, inputting the file name, and then completes the part program by selecting specific data using soft keys or the like.

However, data files are generally filed by type, such as tool data, cutting condition data, tool holder shape data, chuck shape data, tail stock data, tooling data, parameters, etc., so the file data displayed on the screen as reference data. This will include data other than the data needed for the programming process. Therefore, the operator has to search for the required data from among them, and requires skill in using the device. Also, in the programming process,
There are times when it is necessary to extract reference data from multiple data files at the same time, which necessitates repeating the data file selection operation many times, which poses a problem in that the efficiency of program creation is not good.

The present invention has been made in view of the above points, and provides an interactive automatic programming device that reduces the burden on the operator by automatically extracting only item data to be referenced in the program process from all data files. This is what I am trying to do.

(Means for Solving the Problems) According to the present invention, in an interactive automatic programming device for creating an NC program including control programs for a plurality of machining processes, a dedicated A storage means for storing input data from the screen, a display means for displaying the dedicated screen, a storage means for storing a plurality of data files containing a plurality of item data, and a storage means related to the data input to the display means. It is possible to provide an interactive automatic programming device characterized by comprising a selection display means for displaying only item data corresponding to the creation process from among the data files to be created.

(Function) The interactive automatic programming device of the present invention can select and display only the reference items of the data to be input next from the data file based on the input items (cursor position) on the dedicated input screen. , input processing can be performed quickly.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an example of a hardware configuration when an interactive automatic programming device is used with an NC device. The arithmetic processing unit (CPU) 1 has N
A tape reader 2 for reading NC commands from the C tape, a CRT 3 for displaying program information and machine operations, and a keyboard 4 for manually inputting data such as modifying programs are connected to the system including the NC device. ROM 5 stores various control programs for efficient operation, part programs store control programs for each part for cutting, etc., and non-volatile memory stores various data necessary for machining in file format. It has a memory 6 and the like.

Further, a readable/writable RAM 8 is connected to the pass line 7 of the CPU t, and is connected to the motor 11 of the movable part of the machine tool via the position control means 9 and the speed control means 10.
It is used as a work memory when controlled by the CPUI or to control the display screen of the CRT3. The motor 11 has a tachogenerator (TG) 12 for speed detection and a position detector 13, each of which feeds back actual speed and current position in response to a command signal from the CPUI. The path line 7 is controlled by the input/output control (DI/Do control) section 14.
Signal exchange between the PU and various peripheral devices including machine tools is controlled, and the manual pulse generator 15 allows the machine tool movable parts to manually execute predetermined operations.

FIG. 2 is an example of a part program of the screen dedicated to interactive data input for NC statement creation that is selected for display on the CRT 3 from the initial screen through the display selection screen in the process of interactive automatic programming.

When selecting the rod outer diameter process from this screen display and creating an NC program, after inputting the predetermined process number (PNO) and the x and z coordinate values of the cutting point, place the cursor 21 on rRVJ and press the keyboard. If you press the help key of 4, memory 6
A predetermined data file is selected from , and, for example, rough machining items of cutting condition data corresponding to the material of the part to be machined are displayed on the part program screen.

FIG. 3 shows an example of a cutting condition file, and one data file is composed of data regarding material number 5 (SUS) and material number 6 (S45C).

In general, various types of cutting condition data are stored in files for each material depending on the type of process. The data was displayed on the screen as the value of the definition data. In other words, the operator reads the data corresponding to the type of process being created, that is, rough machining. Since only matching item data is displayed as part of the screen, for example above the soft keys, it is possible to prevent incorrect settings due to misreading of the reference data.

FIG. 4 is an example of a tool data file, and FIG. 5 is an example of a tooling data file. After setting the data for the cutting point on the part program screen shown in Figure 2, move the cursor from 20 to 21 to set the cutting depth.
By pressing the help key again in this state, the data items corresponding to rod outer diameter machining in the tool data and tooling data and the rough machining item data in the cutting conditions shown in Figure 3 will be displayed on the screen. displayed as a section.

In this way, for item data that is simultaneously displayed above the soft keys as reference data, the cursor is placed on the first data part of each item, and if necessary, the data is manually rewritten using the keys to ensure proper data content. You can change the data file to the same data format as the input data from the dedicated input screen at the same time.

FIG. 6 is a flowchart showing the processing flow of the automatic programming process.

When inputting data according to the processing content according to the drawing, for example, by pressing the help key (step a),
Based on the long item (cursor position) on the dedicated screen for input, search only the reference items for the next data to be input from the data file.Step b) Select all the data you want to refer to in the part program screen at once. Display (Step c) When there are many 0 items, scroll display may be used.If the help key is not pressed, the machine performs idle cutting according to the set data, and displays an interactive automatic display. Programming process proceeds (step d)
.
