Abstract: A numerical controller is provided with an axis motion control unit configured to control the motions of a table axis and a press axis according to a machining program. The axis motion control unit starts the motion of the press axis for a first block at a first top dead center, if the state of the table axis satisfies a condition adapted for the start of the motion of the press axis for the second block and if the motion of the press axis for the first block is not completed, and the axis motion control unit starts the motion of the press axis for a second block at a second top dead center lower than the first top dead center, thereby overlapping the motions of the press axis for the first and second blocks.

The control unit makes it easier for the coil protection torque restriction to be preferentially implemented in a low rotation operating region in which a motor operates at a low rotation speed equal to or lower than a predetermined value, and makes it easier for the cooling oil protection torque restriction to be preferentially implemented in a high rotation operating region in which the motor operates at a higher rotation speed than in the low rotation operating region.

Abstract: A numerical controller generates movement command data, and performs an interpolation process based on the generated movement command data to generate and output interpolation data. Further, in the case of a state in which a press operation in punch press machining is started from a different position from a position of a preset rising edge, an overlap time is calculated based on a position of a punch head when the press operation is started, and an output timing of interpolation data related to an axis controlling the press operation is controlled based on the calculated overlap time. In this way, even when there is a change in press stroke, a dead time may be prevented from being generated.

Abstract: The numerical controller determines a possibility of interference between a tool and an obstacle on a workpiece and, based on the determination result, switches the end point position of the rising motion of the tool in command data to a retreat position from a rising edge or stops the movements of X/Y axes by a next command block until rising motion of a press axis of the machine tool by the command data is completed. In this way, wasteful deceleration is prevented from occurring when interference between the tool and the obstacle is avoided during machining.
