The useless execution of the interference check is automatically omitted, and the processing speed of the numerical controller is improved.

A syntax error check and a tool interference check of the machining program are performed once by the trial machining performed as a process before the actual machining, and in many cases, the machining program and the tool-related data are changed when shifting from the trial machining to the actual machining. If the machining program or tool-related data is changed without being performed, the trial machining is performed again, so there is a high possibility that the syntax error check and tool interference check of the machining program during actual machining will be omitted. In particular, the processing speed of the numerical controller during actual machining can be effectively improved regardless of hardware resources.

In the above-described embodiment, the date and time of creation and editing of the machining program file, the date and time of execution of the syntax error check, and the date and time of execution of the tool interference check are recorded in the machining program information file stored in the machining program information file memory 21. However, as shown in FIG. 5, the information used for the determination of the necessity of the check can be written as a comment * of the machining program, thereby determining the necessity of the check. FIG.
In the table, "* MAKE" indicates the date and time when the machining program file was created and edited, "* A_CHECK" indicates the date and time when the syntax error check was performed, and "* B_CHECK" indicates the date and time when the tool interference check was performed.
