Abstract

PURPOSE:To save the time required for generation of a working program by executing the plotting of a working shape and program check on a graphic simultaneously with the formation and edition of the working program. CONSTITUTION:The numerical controller has a working program 1, an edition means 2b, a buffer 3, a display processing means 4, a display means 5, a memory 6, a data analysis means 7, and a graphic means 8. The edition means 2b is provided with a condition information deciding means 9 for deciding the validity of execution of one block so that the working shape can be plotted on a graphic simultaneously with the formation/edition of the working program. After checking the formation of one-block data, the program is analyzed and displayed as a graphic and a program error is detected by program analysis. Consequently, the generating time of the working program can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a numerical control device (hereinafter referred to as CNC) that uses a machining program creation/editing function to graphically display a generated program as a tool trajectory.

[Conventional technology]

FIG. 4 shows a conventional configuration diagram for creating, editing, and displaying a bonus program.

Next, the operation of the prior art will be explained with reference to the flowchart of FIG. FIG. 5(a) is a flowchart for creating a new machining program.

Edit means (2a) on editing buffer 1 (3) in step 1
In step 2, the display processing means (4) reads the machining program on the editing buffer (3) and performs an input operation using the processor 3 that displays it on the display means (5). It is determined whether or not the process has ended. If not, the process returns to step 1 and the next block is input. If the process has ended, the contents of the buffer (3) are stored in the memory (6) in step 4, and the process ends.

Fifth (;i1(b) is the process when editing a machining program already stored in the memory. Step 1
1, the editing means (2a) reads from the memory (6) the vanofa (3).
) The processing program specified above is read out, and in step 12 the display processing means (4) reads the editing bar/sofa (3) L.
The machining program is displayed on the display means (5).

In step 13, the editing means (2a) edits the machining program. In step 14, it is determined whether or not the editing is finished. If not, the process returns to step 12 and the next editing is performed. If the editing is finished, the contents of the buffer (3) are stored in the memory (6) in step 15, and processing is continued. It ends.

FIG. 5(c) shows the processing when executing the created/edited machining program. In step 21, the machining program specified for execution is read from the memory (6) onto the buffer (3), in step 22 the machining program is analyzed, and in step 23, the display processing means (4) displays the data based on the analyzed program. A graphical display is provided on the display means (5). In step 24, it is determined whether or not the check has been completed. If not, the process returns to step 21, and if the next block has been read, the check is determined to have been completed and the process ends.

[Problem to be solved by the invention]

Conventional CNC machining program creation/editing functions are configured as described above, so there was a problem that program errors were not known until the program was executed, and it took a lot of time to correct program errors each time. .

This invention was made to solve the above-mentioned problems, and aims to provide a CNC that can simultaneously draw a machining shape graphically and check the program when creating and editing a machining program.

[Means to solve the problem]

The CNC according to the present invention is equipped with a condition determination means for determining whether or not one block can be executed so that the machining shape can be graphically drawn at the same time as the machining program is created and edited.

[Effect]

The condition satisfaction determination means in the present invention checks whether one block data is satisfied, analyzes the program, displays it graphically, and detects a program error through the program analysis.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, machining program (1) indicates a machining program that performs creation and editing. The editing means (2b) creates and edits the machining program on the editing screen. buffer(
3). A buffer for storing a machining program created and edited by the editing means (2b) is shown. Display processing means (4
) displays the machining program on the buffer (3) (
5) It is displayed on top. Memory (6) indicates a memory that stores the machining program that has been created and edited. The data analysis means (7) analyzes the machining program created and edited by the editing means (2b). Graphic means (8) is. This is for graphically displaying the data analyzed by the data analysis means (1). The condition satisfaction determining means 0) determines whether the creation and editing of the I block has been completed.

The editing means (2b) is the conventional editing means (2a) including a condition satisfaction determining means (9).

Next, the operation will be explained. FIG. 2 shows the configuration diagram in detail in the form of a flowchart. Here, the condition fulfillment determining means is to determine the completion of one created/edited block, and the determination is made by operating the EOB key when creating a new block, and by operating the EOB key when editing (correcting). The condition is satisfied when the indicated cursor is positioned after the EOB code of another block or the changed block. In step 3l, it is determined whether or not the machining program creation/editing is complete, and if it is, the creation/editing is determined to be complete and the process ends. If not completed, in step 32, the machining program is read from the memory (6) onto the buffer (3) if it is to be edited, and if it is to be newly created, it is created and edited by the editing means (2b). In step 33, it is determined whether or not the execution condition is satisfied. If not, the process returns to step 31 to determine whether the creation/editing is finished. If it is satisfied, one block of the machining program is buffered in step 34. (3) Read from above, and the program is analyzed by the data analysis means (7). In step 35, the data analyzed in step 34 is displayed graphically on the display means (5). The above cycle continues until the creation and editing of the machining program is completed. If a program error occurs during this time, the program error will be displayed and the process will end.

In the above embodiment, the graphic display is displayed on the right side of the editing screen, but the display is not limited to the right side as long as the editing screen and the graphic display are displayed at the same time.

Further, although the condition satisfaction determining means determines whether the condition is satisfied in only one block, it may be determined whether the condition is satisfied in a plurality of blocks.

〔Effect of the invention〕

As described above, according to the present invention, the machining program editing function also has the function of drawing the machining shape of the machining program, and the machining shape is drawn every time block data is created or modified. Therefore, program errors can be discovered during editing and can be corrected or revised immediately, which has the effect of shortening the time required to create machining programs.
