  • Patent number: 10739753
    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.

The housing covers both axial ends of the stator and rotatably supports the rotating shaft. The liquid coolant is provided in an internal space formed in the housing to flow into at least part of the annular gap formed between the radially inner peripheral surface of the stator and the radially outer peripheral surface of the rotor. The flow direction regulating member axially faces an axial end face of the rotor through an axial gap formed therebetween and regulates the flow direction of the coolant by means of the axial gap.

  • Patent number: 10514674
    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.
