Abstract

PURPOSE:To economize a memory capacity and to shorten the time required for program generation while keeping the compatibility with the other types of device by making it possible that working programs in 2>= kinds of language form exist in a storage device together. CONSTITUTION:Distinctions of language forms of the first and the second working programs 31 and 32 are stored in a directory of a memory where storage areas of working programs are stored. Before the start of operation, the register nember of the working program to be operated is inputted from an operation panel. Contents of the directory 33 are searched to discriminate whether the working program exists or not, and the start of its storage position is stored temporarily. In this case, discrimination code of language forms which are added to programs 31 and 32 are discriminated to set flags, and the use of the first converting program 34 or the second converting program 35 is determined. The first and the second display editing programs 36 and 37 for switching the display of a display device are switched. Thus, working programs having two language forms can be stored and operated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a numerical control device that allows the use of multiple automatic programming languages.

Conventionally, this type of numerical control device (hereinafter referred to as an NC device) has been configured as shown in FIG.

1 is a CPU that performs calculations necessary for controlling the system and controls the system;
2 is a memory, 3 is an input device for inputting a program from an external source such as a tape reader, 4 is a display device for displaying various information for the operator, and 5 is a plurality of units for inputting various commands and data. 6 is a servo control unit that controls the rotation angle and rotation speed of the servo motor 10 in accordance with the moving leaf outputted from the CPU 1; 1 is a servo control unit that inputs and outputs various control signals to and from the processing machine; Input/output interface section, 8 is a common bus line (pass line) connecting each module, 9 is a processing machine, 10 is a servo motor that moves the table, 11 is a detector for detecting the position, 12.13 is a machine and This is a cable that connects a numerical control device.

Next, the parts related to the present invention regarding the operation will be explained.

First, the memory 2 is preloaded with a control program for controlling the operation of the entire system and constants necessary for calculations, and when the NC device is powered on, execution of the control program is started from the KCPU1, and the processing machine 9 It performs operations corresponding to inputs from and from the operation panel 5.

Prior to driving, a Canadian program is inputted from the input device 3 and loaded into the memory 2. In order to classify a plurality of Canadian programs, they are numbered and stored. The operator inputs a number from the operation panel 5 to designate the Canadian program to be operated and starts it. The NC device searches the storage area for a specified program, sequentially reads the commands of the program, performs necessary conversion, and outputs the data to the processing machine 9 and the servo control section 6 to perform the operation. Furthermore, by displaying any part of the contents of the crab program on the display 4 and allocating some of the contacts on the operation panel 5 for editing operations, the stored crab program can be edited.

Next, the general structure of the program will be explained with reference to FIG.

The Canadian program 21 is input by the display editing program 24 through the input device 3. When automatic operation is started, the conversion program 22 reads and decodes the contents of the Canadian program 21 one block at a time, converts it into a predetermined formant, and passes it to the main program 23. The main program 23 partially converts the data at each timing. Convert it to
The servo controller 6 and the external input/output interface 7 output the appropriately converted Canadian program data.

When the output is completed, the conversion program is started again and the next block of data is processed.

However, at present, in general NC devices, a word addressing method using l5O-EIk codes is used for the Kanni program, and the Kanni program is stored using only this one method. In recent years, in order to improve the efficiency of creating Niprograms for use, NC devices with a built-in automatic programming function have appeared. There are two types of this method: one in which the program entered in an automatic programming language is converted into the conventional word address system and stored at the time of input, and the other in which the input in the automatic programming language is memorized as is and used for driving. be. The latter method requires less memory capacity to store the same function-added program, the original input remains as is, and it is shorter than the former, making it easier to edit. However, since the automatic programming language has a unique formant, it is not compatible with Canadian programs used in other models.

In this way, conventional NC devices store Canadian programs in only a single language format, so NC devices with automatic programming functions that have excellent storage capacity and editing functions are not compatible with other models, and cannot be automatically programmed. This method has the disadvantage that it cannot handle special machining that has not been prepared as a processing item for programming.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by making it possible to coexist Canadian programs in two or more language formats in a storage device,
The objective is to provide an NC device that saves memory capacity while maintaining compatibility with other models and also has an automatic program function that is easy to edit.

This invention will be explained below.

FIG. 3 shows a schematic diagram of the structure of a control program used in an embodiment of the present invention, in which 31 is a first program written in an automatic programming language, 32
is the second Canadian program written in the EIA formant.

1st. The classification of the language format of the second Canadian program 31, 32 causes the storage area of the program to be stored in the directory 33 in which it is stored.

The first conversion program 34 is a program for converting programs written in an automatic programming language, and the second conversion program 35 is for processing BIA formant programs. 36 is a first display editing program, which is a routine for editing a Canadian program written in EIA formant; 37 is a second display editing program, which is a display editing routine for automatic block programming. 38 determines and processes flags sent according to the language format of the program! This is a programming language format discriminator that switches the rate.

Next, the operation will be explained. Before starting operation, input the registration number of the machining program to be operated from the operation panel 5 (Fig. 1).

The directory 33 in the memory 2 is searched to see if the Kanji program exists, and the beginning of the storage location is temporarily stored. The first or second rust removal program 31.
determine the language format identification code attached to 32, set the flag, and use the first conversion program 34;
It is determined whether the second conversion program 35 is to be used or not.

Further, the first display editing program 36 and the second display editing program 21 for switching the display on the display 4 are switched. In this way, Canadian programs in two language formats can be stored, operated and edited simultaneously.

In the above embodiment, an example of language switching of the 2'M4 type was shown, but by increasing the types of processing routines,
It is possible to store a mixture of Canadian programs in many different languages, and to operate and edit them by switching processing. Language format when calling a subprogram during automatic operation! By switching the internal flag for "11" usage, machining program programs with different language formats can be mutually called as subprograms.

As explained in detail above, the present invention is provided with a memory for storing Canadian programs of different programming language systems, and a means for calling these Canadian programs as subprograms and operating them continuously. This allows you to use the length B which allows you to quickly create a program, and special processing that cannot be done with automatic programming can be done using the EIA formant, reducing the time required to create a program. This also has the advantage of improved flexibility.
