[0003] First, it is selected beforehand whether a part program for laser or a part program for turret punch press is executed by the mode selection input device 6. If the laser part program is selected by the mode selection input device 6, the laser part program number is input by the laser part program number input device 7 and the laser part program analysis processing device 3 is input. To perform an analysis process, and the servo and laser control device 5 controls the servo and laser to perform processing. If the turret punch press part program is selected by the mode selection input device 6, the turret punch press part program number is input by the turret punch press part program number input device 8 and the turret punch press part program is input. The press part program analysis processing device 4 performs an analysis process, and the servo and laser control device 5 controls the servo and laser to perform processing.

[0004]

In the conventional method, it is determined whether to execute a laser part program or a turret punch press part program in advance, so that the functions are independent from each other. Therefore, when the mode for executing the laser part program is selected, the turret punch press part program cannot be executed even if the turret punch press part program is designated as a subprogram. Further, when the mode for executing the part program for the turret punch press is selected, there is a problem that the part program for the laser cannot be executed even if it is a subprogram.

[0005] The present invention is to solve the above problem, and automatically identifies whether a part program is for a laser or a turret punch press, and performs analysis processing according to the mode in which the part program is identified. By doing
An object of the present invention is to provide a numerical controller for a laser processing machine that can arbitrarily execute any of a laser part program and a turret punch press part program.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a numerical controller having a mode for performing processing by a laser part program and a mode for performing processing by a turret punch press part program. A part program number reader that reads the program numbers of the laser part program and the turret punch press part program, and an automatic discriminator that automatically identifies the program type from the data type at the beginning of each program when the program is read A mode discriminator is provided, and two types of analysis processing for laser are performed when it is determined to be a part program for laser, and analysis processing for turret punch press is performed when it is determined to be a part program for turret punch press. Equipped with a part program analysis processor It is obtained by way.

Further, according to the present invention, the program number written in the part program is read by the part program number reading device, and the next part program to be subsequently executed is determined. Are automatically identified and determined.

[0008]

According to the above-mentioned means, whether the part program is for a laser or a turret punch press is automatically identified by the mode automatic identification device based on the type of the identification code at the head of the program. Part program analysis processing is performed for each processing mode by the part program analysis processing device provided independently for the punch press and the part program for the turret punch press according to the identification code at the beginning of the program. Arbitrarily executed.

Further, by writing the program number to be executed next in the preceding part program,
The part program number is read by the part program reading device, and the operation mode of the part program is automatically identified by the mode automatic identification device, so that the laser part program and the turret punch press part program are arranged in an arbitrary order and in an arbitrary number. Are executed continuously.

1 is a block diagram showing a configuration of a numerical control device of a laser beam machine according to the present invention shown in FIG. In FIG. 1, 1 is a part program number reading device, 2 is a mode automatic identification device for automatically recognizing and identifying a laser part program and a turret punch press program, 3 is a laser part program analysis processing device, and 4 is a turret punch. The press part program analysis processor 5 is a servo and laser controller.

The function and operation of the present invention will be described below with reference to the drawings. The part program group in the numerical value control device of the laser beam machine according to the present invention has a level structure shown in FIG. That is, the part program to be executed first becomes the main program, the part program to be executed next specified by the main program becomes the first layer subprogram, and the next program specified by the first layer subprogram is executed. The power part program becomes the subprogram of the second layer, and has the same hierarchical structure until the final subprogram. The part program number reading device 1 shown in FIG. 1 reads the number of the part program to be executed next to the subprogram for each nesting from the main program, and terminates the program being executed, and then the next nesting designated in the program. Part program, which is a subprogram of, is executed continuously.
When the execution of each part program is started, the mode automatic identification device 2 identifies whether the part program is for laser or turret punch press based on the identification code at the head of the part program.

FIGS. 3 and 4 show an example of an identification code according to an embodiment of the present invention. FIG. 3 shows a leading part of a laser part program, and FIG. 4 shows a leading part of a turret punch press part program. As shown in FIG. 4, machining conditions are included only at the beginning of the part program for the turret punch press. In this embodiment, the part program is used for the laser depending on the presence or absence of the machining condition at the beginning of the part program. The automatic mode discriminating apparatus 2 discriminates whether the object is for a turret punch press. In the present embodiment, the mode is automatically identified based on the presence or absence of the processing condition at the head of the part program. However, it goes without saying that another identification code may be used.

The program numbers written in the preceding part programs in this way are read by the part program number reading device 1, and the operation modes of the part programs which have started to be executed are identified by the mode automatic identification device 2, and are separately executed. The program is analyzed by the provided laser part program analysis processing device 3 or the turret punch press part program analysis processing device 4 and processing commands are output to the next stage. The servo and laser control of the next stage which input these commands are performed. The device 5 controls the numerical controller to perform laser processing or turret punch press processing.

As is clear from the above description, according to the present invention, a subprogram is formed by a laser part program for coordinate rotation, mirror image, scaling, and processing of an arbitrary shape, and pattern processing of a simple shape is performed. Numerical control device for laser processing machine with high operating efficiency, which can execute any number of part programs in any order by creating subprograms with turret punch press part programs and inheriting these subprograms in a hierarchical structure Can be realized.
