Abstract

PURPOSE:To avoid the useless delay of the time needed for the end of a program analyzing process by newly defining an undefined error detected by a program analyzing means at this detecting time point to correct and edit a working program and starting continuation of the program analyzing process by the edited defined sentence. CONSTITUTION:A working program supplied by a program input means 1a is analyzed by a program analyzing means 1b. In this case, a correcting/editing command is given to a program editing input means 1c to newly define an undefined sentence at a time point when an undefined error is detected with the variables, pattern numbers, etc., contained in the working program. When said correcting/editing job is through, a program changing means 1d starts continuation of the program analyzing process by the newly defined sentence and its following undefined sentence. Thus it is possible to reduce the debug processing load and also to avoid the delay of the time needed for the program analyzing process.

[Problems to be solved by the invention] The conventional automatic programming device is configured as described above, and analyzes the machining program in order from the first line, so if there is an undefined variable or figure number, the At this point, an error message is output and the analysis process ends. Therefore, it is necessary to use the editing function again and edit the machining program again, which causes problems such as troublesome operation.

This invention was made to solve the above-mentioned problems. When analyzing a machining program, if variables, figure numbers, etc. are undefined, the machining program can be automatically edited and corrected. The purpose of this invention is to obtain an automatic programming device that can continue the analysis process again.

[Means for Solving the Problems] The automatic programming device according to the present invention has an automatic programming device that, when a machining program manually created by a human program means is analyzed by a program analysis means, there are no errors in variables, figure numbers, etc. in the machining program. When a definition error is detected, the program editing manual means is commanded to perform a correction edit to newly define an undefined statement. After the correction editing, the program change means edits the newly defined definition statement and the next defined undefined statement. The parsing process continues from the beginning of the sentence.

[Operation] According to the program editing means according to the present invention, after the undefined error detected by the program analysis means is newly defined at the time of error detection and the machining program is corrected and edited, the program changing means Since the analysis processing of the machining program is continued from the definition statement, the analysis processing completion time is not unnecessarily prolonged.

[Embodiment] FIG. 1 is an overall configuration diagram of an embodiment of an automatic programming device according to the present invention. As is clear from FIG. 1, this embodiment includes a program input means (1a) for inputting a machining program using a predetermined data input device, and a program input means (1a) for inputting a machining program using a predetermined data input device. If variables, figure numbers, etc. are undefined, a program analysis means (1) outputs an error message and selects an automatic editing mode to modify and edit undefined statements.
b) and a program editing manual means (LC) for correcting and editing the machining program by inputting from the keyboard a definition sentence that newly defines an undefined sentence when the automatic editing mode is selected.
After editing the program, the program changing means (1) executes the analysis process of the machining program from the newly defined definition statement, and then instructs the analysis process to the undefined statement.

(12) is an NC device that processes data transmitted via the interface (11) to drive and control the machine tool (14), and (13) is a bus that transmits each data.

Next, the operation of the automatic programming device according to the present invention will be explained with reference to the flowchart shown in FIG.

(1) Step S1 When set to program editing mode, cpU (1) receives input of a machining program from the keyboard (6). This input program is stored on a flexible disk (IO) via memory (2) or input/output device (9).
).

(2) Step S2. S7 When set to program analysis mode, the CPU (1) analyzes the manually-written machining program in order from the beginning. If there is no error, the analysis process ends, but if variables etc. are undefined, go to (step S3), and if there are other errors, go to C
Output an error message to RT(5) (step S
7).

(3) Steps 33 to 5 When an undefined error occurs in the program analysis process of step S2, the CPU (1) selects automatic editing mode (step S3). Then, the CPU (1) stores the line in which the undefined error occurred and the undefined variable name or figure number in the memory (2) (step S
4).

c p U (1) calls the program editing function, leaves a blank line in front of the line where the undefined error occurs, and waits for input from the keyboard (6). For example, suppose that the machining program shown in FIG. 5 is analyzed. Then, since the figure "L4" is not defined at the line ■, the memory (2) contains the line ■ where the undefined error occurred and the figure "L4".
4" is stored. Therefore, ■ line and ■
A blank line will be created between the lines, and the figure "L4" can now be defined.

When you finish defining undefined variables or figure numbers,
The CPU (1) retrieves from the memory (2) the information on which line the undefined occurs and the information on the number of the newly defined line, and ends the automatic editing mode (step S5).

(4) Step S6 When the automatic editing mode is ended, the CPU (1) first analyzes the newly defined line, and then starts the analysis again from the occurrence of undefined errors. To explain this with reference to FIG. 5, first, the data of the figure "L4" inserted between the ■-th line and the ■-th line is analyzed, and then the program is analyzed sequentially from the ■-th line.

In the above example, the operation was shown as an operation during program analysis, but since a predetermined line can be stored in the memory (2), when using the program editing function, it is possible to write a statement that refers to a previously undefined figure. If you select the automatic editing mode when writing, a blank space will be provided before the line where you can define the reference figure data, and after the automatic editing mode ends, the symbol waiting for keyboard input (hereinafter referred to as the cursor) will be Return to the line where automatic editing mode was called. For example, in [1] of FIG. 6, the undefined figure rL10J is referred to in the ■th line. If you switch to automatic selection mode here,
As shown in [2], there is a blank line between the [stock] line and the ■ line, the cursor is on this blank line, and the shape rL10
Wait for J to be defined.

When the definition is completed and the automatic editing mode is exited, the cursor is placed again at the end of the line ■, as shown in [3].

[Effects of the Invention] As explained above, according to the present invention, when an undefined statement error is detected during analysis processing of a machining program consisting of a plurality of definition statements written in a certain order, a new Insert the definition statement into the machining program, modify and edit the program,
Since the analysis process continues from the new definition statement, the burden of debugging processing is reduced and the program analysis processing time can be saved from increasing.
