ABSTRACT:
A numerical controller capable of obviating the waste of a workpiece by machining such that a position deviation by learning control is converged and automatically performing storage of correction data and actual machining. A tool and the workpiece are moved to noninterfering positions. In a learning control interval from the issuance of a learning control start command to the issuance of a learning control end command, the input and output are turned on so that the learning control is performed to input the position deviation and create and output the correction data. Processing in the learning control interval that involves the learning control is repeatedly executed a set number of times by idling operations. The obtained data is automatically stored in the numerical controller, the tool and the workpiece are moved to interfering positions, and the position deviation is corrected based on the correction data, whereby actual machining is performed. The correction data is automatically stored and the actual machining is performed using the correction data without wasting the workpiece, so that the cycle time can be shortened.
