Abstract

PURPOSE:To obtain the NC device capable of designating a call of a subprogram in a working program, a call of a tool, a call of a tool correction amount, and a call of a work coordinate system by the name instead of by the number. CONSTITUTION:The numerical controller is constituted so that in the case of executing a call of a subprogram in a working program, a call command of the subprogram is executed by the name of the working program set by a program name setting means 106, its working program name is converted into the working program number by a program name converting means 104, and the subprogram is called. Since the respective calls are executed by the name instead of the number, for what working each of them is used can be discriminated easily, a generation miss of the working program decreases, and also, a fact that a work is spoiled by executing an erroneous working program decreases.

3) Explain.

Next, the name of the corresponding index is read from Table 1 (step S1107), and it is checked whether or not it matches the program name of the program command #define (step S1108). If they do not match, it is checked whether the check has been completed for all indexes (step S110).
9) If not completed, the next index is set (step S1110), and the processes of step S1107 and thereafter are performed. If it is determined in step S1109 that the process has been completed, a new #d is added to the program name / number correspondence table.
The name and number instructed by efine are added (step S1115), and the process ends. If they match, the number corresponding to the index is read (step S1111), and it is checked whether or not the number matches the number designated by #define (step S11).
12). If they match, the name portion of the program name / number correspondence table is rewritten (step S1113), and the process ends. If no match is found, #defi
The name and number instructed by ne are stored in different indexes of the correspondence table, and if the name of the correspondence table is rewritten, two program numbers with the same name will be stored, so an error display will be displayed (step S1114), The process ends.

As described above, the first, second, third,
According to the NC device of the fourth aspect of the present invention, it is provided with a name setting means for setting each name of the machining program, the tool, the tool correction amount, and the work coordinate system, and a name converting means for converting each name into a number. Since the machining program, tool, tool compensation amount, and workpiece coordinate system are called by their respective names, it is easy to determine what each machine is used for machining, and there are few machining program creation errors. In addition, there is an excellent effect that the wrong work program is not executed and the work is ruined.

According to the NC device of the fifth invention,
A name / number setting means for setting the correspondence between each name and number of the machining program, tool, tool compensation amount, and work coordinate system is provided, and each name / number of the machining program, tool, tool compensation amount, work coordinate system is provided. Since the setting of the correspondence table can be set from the machining program, it is possible to reduce the operation work of the NC device by the operator, and there is an excellent effect that operation mistakes can be eliminated.
