Patent number: 10551825Abstract: To provide a numerical controller that is capable of analyzing a machining program so as to determine whether machining is machining placing emphasis on accuracy and machining placing emphasis on speed and vary an allowable speed difference. The numerical controller includes a determination unit and a corner deceleration control unit. The determination unit analyzes a machining program so as to determine which machining is to be performed between machining placing emphasis on accuracy and machining placing emphasis on speed. The corner deceleration control unit executes corner deceleration control based on a speed difference between cutting feed speeds on blocks leading and following a corner and an allowable speed difference which is predetermined. At this time, the corner deceleration control unit varies the allowable speed difference in accordance with a determination result of the determination unit.Type: GrantFiled: November 21, 2017Date of Patent: February 4, 2020Assignee: Fanuc CorporationInventors: Shintarou Zeniya, Takeshi Mochida

Patent number: 10514674Abstract: 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.Type: GrantFiled: July 19, 2018Date of Patent: December 24, 2019Assignee: Fanuc CorporationInventors: Takashi Satou, Takeshi Mochida
