  • Patent number: 9791846
    Abstract: To include an analysis processing unit that obtains a movement command for moving on a movement path in a machining program, and vibration conditions for vibrating along the movement path, a command-movement-amount calculation unit that calculates a command-movement amount per unit time, a vibrational-movement-amount calculation unit that uses the vibration conditions to calculate a vibrational-movement amount per unit time at a time corresponding to the movement command, and a movement-amount combining unit that combines the command-movement amount with the vibrational-movement amount to calculate a combined movement amount, and that acquires a movement amount within the unit time such that a position, which has moved from a reference position for calculating the combined movement amount by the combined movement amount, is located on the movement path.

  • Publication number: 20170220091
    Abstract: The present invention provides a power-supply management device which can efficiently connect and disconnect power supply to an electric-powered section, and a machine tool including the power-supply management device. The power-supply management device (101) detects a synchronization command of a control program, and compares an operation time of the electric-powered section between synchronizations in each control system which is a synchronization target by the synchronization command on the basis of the detected synchronization command. Then, the power-supply management device (101) disconnects the power supply to the electric-powered section belonging to the control system except the control system having the maximum operation time of the electric-powered section between the synchronizations, and restarts the power supply at the end of the synchronization in each control system.

  • Patent number: 9703282
    Abstract: A portable manipulation command input device, including a sub-console panel attachable to and removable from an automatic lathe apparatus main unit, and includes an input unit to receive input of a manipulation command to the automatic lathe apparatus main unit, a display unit to display information on the automatic lathe apparatus main unit, and a radio communication unit to communicate with the automatic lathe apparatus main unit. The sub-console panel includes a detection unit and a control unit formed with the automatic lathe apparatus main unit. The detection unit includes a radio ID tag and a radio ID reader detecting the sub-console panel being placed within a predetermined range of the automatic lathe apparatus main unit. Depending on a detection result by the detection unit, the control unit allows or restricts manipulations of the automatic lathe apparatus main unit, and allows display of the information even when restricting the manipulations.
