Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic programming method, and in particular, a part program is created by using a command statement predetermined in the system, and the system is executed to execute the part program. The present invention relates to an automatic programming method that is executed and converted into an NC program in a format that can be executed by an NC device and output.

<Prior art> An automatic programming device that automatically creates an NC program is composed of a graphic display device, a keyboard, an input device such as a floppy disk, etc. in addition to the main unit, and is extremely useful because it can create an NC program easily, quickly and accurately. Is.

The main body of such an automatic programming device has a computer configuration, and software (system program) for creating an NC program is stored in advance in a system program area of a built-in main storage device so that a predetermined automatic programming language (APT Or FAPT) and use N
Create a C program. That is, (a) The part shape is defined by points, straight lines, and arcs using simple symbols (figure definition), and the tool path is defined by using these defined points, straight lines, and arcs (motion statement definition). ),
A part program in an automatic programming language is created, and (b) subsequently, the part program in an automatic programming language is converted into NC data consisting of NC data (EIA code or ISO code) in a format that can be executed by an NC device.

<Problems that the invention is trying to solve> By the way, when creating a part program, the material is drawn on the display screen and drawn, and the function is released as the tool moves according to the definition of the motion statement. , It is possible to give an arbitrary function by using an arbitrary command statement such as a function to draw not only the shape of the part but also the mechanical shape of the NC lathe used for actual machining on the display screen, for example, the shape of the chuck, tailstock, etc. And very convenient.

However, an automatic programming device that automatically programs using the conventional FAPT language can only execute command statements prepared by the system, that is, such as the function of filling materials and the function of drawing arbitrary shapes such as chucks and tail stocks. No command statement is prepared.

From the above, it is an object of the present invention to provide an automatic programming method capable of facilitating programming work by providing these functions to an automatic programming device that does not have command statements such as a material filling function and a function of drawing an arbitrary shape. That is.

<Means for Solving Problems> According to the present invention, the above-mentioned problem is to register the name of any command statement not defined in the system and its format format, and the command statement defined in the system. Using a means for registering a subprogram created by using the macro as a macro corresponding to the arbitrary command statement, and a part program using a command statement defined in the system and an arbitrary command statement not defined in the system Means for creating, when the system executes the arbitrary command statement when executing the part program, means for translating the arbitrary command statement according to the registered format, and the macro by the optional command statement And a means for executing a predetermined process according to the macro.

<Operation> The name and format of an arbitrary command statement not defined in the system are registered, and the subcommand created using the command statement defined in the system is used as a macro to define the arbitrary command statement. Register in correspondence with. Then, a part program is created using a command statement defined in the system and an arbitrary command statement not defined in the system, and when the system is the arbitrary command statement in executing the part program, Translate the arbitrary command sentence according to the registered format, and then,
The macro is called by an arbitrary command statement, and predetermined processing is executed according to the macro.

<Embodiment> FIG. 1 is a block diagram of an apparatus for implementing the automatic programming method according to the present invention.

11 is a ROM in which loading programs are stored, 12
Is a processor for performing automatic programming processing, 13 is a system program read from an input device, RAM for storing various parameters and processing results, 14 is an NC data storage memory, 15 is a keyboard, and 16 is a command defined in a system statement. A file memory for storing various arbitrary sentence files (macro) created in advance using sentences, 17 is a display device (CRT), and 18 is an NC data output device for outputting the created NC program to an external storage medium. CH on the display device (CRT) 17 is a chuck, TS is a tailstock, and W is a material.

In advance, the operator uses a command statement defined in the system statement as a subprogram (macro) for displaying the material shape having the length “l” and the diameter “d” in the coordinate position as shown in FIG. File memory created using
It is registered in 16 as a "BLANK file" 16a and an arbitrary command statement for executing the macro is registered as "BLANK, l, d, R, z, x". However, "R" is a modifier indicating the right side in the + Z direction with the X axis as a boundary. Similarly, the macro corresponding to any command statement "CHACK, ..." Meaning chuck shape drawing is used as a "CHACK file" 16b, and any command statement "TAIL ,.
Create a macro corresponding to "..." as "TAIL file" 16c and register it in the file memory 16.

Next, the operator shall create a part program for lathe processing according to a predetermined procedure, and operates the keyboard 15 to operate PART, @ REIDAI (1) MCHN, TURN, ZX, ABS (2) ..・ ・ BLANK, ・ ・ ・ CHACK, ・ ・ ・ TAIL, ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ FROM, P100 （３） ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ FINI PEND ( 4) Create a part program with and store it in the memory 14.

However, (1) is an instruction to start the part program, and "REIDAI" is a headline.

(2) indicates the type of NC machine. In the case of lathe processing,
Use TURN and MILL for milling. “ABS” indicates an absolute command (INCR is used for an incremental command.) (3) specifies the machining start point P100, (4) indicates the end of the part program.

Then, when the conversion process is started, the NC program can execute the part program 1 by the automatic programming function.
Converted to NC data. FIG. 2 is a flow chart of such NC conversion processing. Hereinafter, description will be given along the flow of processing in FIG.

The processor 12 reads one block of the part program 1 (step 101), determines whether or not one block is a PEND indicating the end of the part program, and if it is PEND, terminates the processing (step 102), and if not PEND ,
It is judged whether it is an arbitrary command statement (step 103), and if it is not an arbitrary command statement, normal conversion processing is performed.
Create NC data (step 104). In the same manner, repeat the processing from step 101, and if it is an arbitrary command sentence in the judgment of step 103, for example, "BLANK, 500,100, R, 250,50", translate the command sentence. Then (step 105), it is judged whether or not the command statement has the format of an arbitrary command statement for filling (step 106), and if so, the "BLANK file" 16a in the file memory 16 is called. And the variables l, d, z, and x in the file are 100 and 50, respectively.
The 0,250,50 are assigned and the filling process is executed, and the material shape is filled and displayed on the CRT screen 17 (step 107). or,
If it is determined in step 106 that it does not have the format of the arbitrary command statement for filling, an error is displayed on the CRT screen 17 and the process ends.

After that, the processing from step 101 onward is repeated in the same manner.
Any command statement is "CHACK, ..." or "TALL,
... ", the chuck shape is displayed on the CRT screen 17, or
The tailstock shape is displayed. Further, it is possible to draw a state in which the material is being scraped off every time NC data for a passage is created.

Furthermore, in the above, the case where the filled display, the chuck, and the shape of the tail stock are displayed has been described, but it is also possible to register an arbitrary part shape and specify the part shape with one command statement.

<Effects of the Invention> As described above, according to the present invention, a subprogram created using an arbitrary command, its format, and a command statement defined in the system is registered as a macro in association with any command statement. A part program is created by using the command statement, and when the part program is executed, the system calls the macro by an arbitrary command statement and executes a predetermined process according to the macro. An automatic programming device that does not have a function for drawing a shape can be provided with these functions to facilitate programming work. Further, since it is possible to specify the display of filling of the material, the display of an arbitrary shape such as chuck, tail stock, etc. and the specification of an arbitrary part shape with only one command statement, the system can be easily expanded.
