Numerical controller having a function of learning control
A numerical controller capable of checking a learning control execution interval for the entry of a command or signal that varies an operation pattern. The numerical controller reads machining programs in succession and sets a flag F to 1 until a learning control end command is read after a learning control start command is read. In a learning control interval during which the flag F is set to 1, it is determined whether or not an inappropriate command or signal is inputted during a learning process such that the operation pattern is varied. If it is concluded that such a command or signal is inputted, an alarm stop or feed hold stop is performed, the cause of stopping is displayed, and learning control is nullified. If any inappropriate command or signal is inputted during the learning process, the operation is stopped and the cause is displayed, so that the machining programs can be corrected with ease. Thus, wrong cutting or the like can be prevented from being caused by the learning control.
