Abstract: A numerical controller controls a machine tool which carries out machining by moving a workpiece or a tool using a periodic operation cycle for repeatedly executing the same operation. The numerical controller stores command data of each execution period of a superposition cycle superimposed with the periodic operation cycle. Command data sets of the superposition cycle are synthesized every execution cycle in synchronization with execution timing of the periodic operation cycle.

Abstract: A commanded speed is acquired by a command program analysis unit, an override is acquired by an override input unit, and the override before input is changed in steps by a stepwise override change unit to the override that is input, in a predesignated time or by a predesignated change amount, and outputs the override changed as an actual override. The actual override is acquired by a speed operation unit in an interpolation cycle from the stepwise override change unit and the commanded speed is multiplied by the actual override to calculate a feed speed.

Abstract: 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.

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.
