When an output command is inputted, all programs including this information are outputted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for searching and outputting a program stored in a numerical control device built into a computer.

Conventional technology] A number 1A ILJ control device (hereinafter referred to as CNC) with a built-in computer
) is a system in which various programs are stored in non-volatile memory such as bubble memory or CMOS memory in the QNC, and processing is controlled by the programs. When searching for a stored program or punch-out outputting a selected program, the search or program output can only be performed using the program number assigned to each stored program.

Problems to be Solved by the Invention A program is usually given a program name for each workpiece processed by the program, and various classifications are made within each workpiece unit. For example, for a program to process a shaft, 5HAFT-1000, MA I
N, 5HAFT-2000, MAIN, 5HAFT-1
000,5 LIB.

5HAFT-2000, SUB, etc. For each shaft unit as a workpiece, the type and program are classified as main programs or sub programs, and each program number is assigned and stored. Therefore, in order to know what kind of programs are currently stored in the CNC, especially what kind of programs are stored for each workpiece such as shift V-shift, 7-lunge, and gear V-, it is necessary to use the conventional method. Searching by program number is inconvenient and time consuming.

Therefore, an object of the present invention is to search for a program stored in a CNC using a part of the program name and output the program, and to provide a numerical control method that can search and output the program for each workpiece. be.

Means for Solving the Problems The program memory is provided to store various programs and program names, and when at least a part of the program name and a program search command are input, the program memory is searched and the input program is searched. When at least a part of the program name and a program output command are input, all program names having the input program name information are displayed on the CRT screen. The above problem was solved by configuring the program memory to be read and output.

Various programs and each program name are registered and stored in the working program memory, and when a part or all of the registered program name is input and a program search command is input, the program memory is searched and the inputted program name is input. Displays all 8 programs including the program name information. Further, when a part or all of a program name is input and a program output command is input, the program memory is searched and all programs including information on the input program name are output.

Embodiment FIG. 1 is a block diagram of main parts of an embodiment of a numerical control device 1 that executes the numerical control method of the present invention.
has a microprocessor (hereinafter referred to as CPU) 10, and the CPL 110 has an RO that stores a control program.
M11. RAM 12 used for temporary storage of data, etc.
Bubble memory and C
13. A non-volatile memory composed of MOS memory, etc.; a gluer/puncher interface for punching out the Niprogram; 14. A CRT display device 15, a keyboard 16, and an axis control circuit 17 for driving and controlling the servo motors and the like of each axis controlled by the numerical control Il device 1ff1 such as a machine tool are connected by a bus 18.

FIG. 2 shows the nonvolatile memory 13 according to an embodiment of the present invention.
This is an explanatory diagram of a program memory 13a and a program management table 13b provided in the program memory 13a. Various programs are stored in the program memory 13a, and program numbers P1 to Pn are stored at the top address of each program.
and the names of the programs PNA1 to PNAn are stored, respectively. Further, the program management table 13b stores the program numbers P1 to pn of each program, as well as the start addresses A1 to An of the program memory 13a. Note that when inputting each program, the program name is input together with the program, and when the program and program name are input, the CPU 1o stores the information in the program memory 13a of the nonvolatile memory 13 and the program management table 13b as described above. Since this point is not the gist of the present invention, the details will be omitted.

Next, the operation of this practical example will be explained with reference to the operation processing flowchart 1- in FIG. The CPU 10 performs the process shown in FIG. 3 at regular intervals. First, when the keyboard 16 is operated and the editing mode is selected, the CPU 10 determines this (step 81), and a program screen is selected on the CRT device 15. If the program screen is not selected (step S2), it is assumed that the search by program name and program output process of the present invention will not be performed, and this process is terminated and the process proceeds to other processes. -6 On the other hand, when the program screen is selected, it is determined whether or not a program search command based on the program name has been input from the soft key on the keyboard 16 (step S3). Determine whether or not a program name has been input (step S4). For example, when searching for a registered and stored program for machining a shaft and 7 lunges, the operator operates the keyboard 16 and selects S HA FT for each workpiece. , F.R.
Input ANGE and press the execution key, then the CPU
10 is a program memory address A1 to A for each program number stored in the program management table 13b.
n, and read out the stored contents of the read program memory addresses A1 to An of the program memory 13a, that is, the program name, and if the read name is 5HAFT or F.
It is determined whether or not RANGE is included, and the program memory 13a is searched (step 85). When a corresponding one is found (step 86), the program names PNA1 to PNAn, program numbers P1 to pn, and contents ff1PC1 to PCn of the program are displayed on the screen of the CRT device 15 as shown in FIG. Step 87). In this way, all currently registered and stored programs whose names contain part or all of the input program name information are displayed with their full names. Also, if you enter r-1000, MA INJ instead of 5HAFT or FRANGE, the program names PNA1 to PNA n will be rlooo, MA.
All program names including INJ PNA1~PNAn
will be displayed. Note that in step S6, if the input program name is not found by searching, an alarm is displayed (step 513).
.

Furthermore, when the operator inputs a program output command using the program name using the soft key when outputting the program using the program name, the CPU 10 executes step S.
8, it is determined that a program output command using a program name has been input, and then it is determined whether a program name has been input as described above (step S9). If a program name has been input, the step S9) described above is executed. Similar to S5, the program memory 13a is searched for a program whose name includes the input program name (Step 5).
10). As a result of the search, if a program whose name includes part or all of the input program name is found (step 511), the program is punched out and output via the reader/puncher interface 14. (step 512). Further, if a program name containing part or all of the information of the program name input by searching in step S10 is not found (step 511), an alarm is displayed as described above (step 514).

Note that if a program search command based on a program name or a program output command based on a program name is not input (step S3, step S8), this process is terminated as it is not a search or output process based on a program name, and another process is performed. Move to processing.

Effects of the Invention As described above, the present invention is capable of searching and displaying a program registered and stored in a numerical control device by program name, and outputting the searched program. By inputting a part of the program name, you can display the program names or output the program names of all programs that have the input program name as a part, so you can program the program for each workpiece such as shaft, 7 lunge, gear, etc. Since it is possible to display all the program names with that name and output the programs, it is possible to easily inform the programs currently registered in the numerical control device, and also to easily search and output the programs. .
