Patent number: 10915086Abstract: A numerical controller which performs program restart after machining is stopped in the middle of a machining cycle is provided with a program restart unit. The numerical controller can use the program restart unit to acquire a restart position located in a machining area defined by the machining cycle, create a new machining area by dividing the defined machining area in the restart position, and restart the machining for the new machining area.Type: GrantFiled: October 3, 2018Date of Patent: February 9, 2021Assignee: Fanuc CorporationInventors: Yasuhiro Ota, Shinichirou Itakura

Patent number: 10838395Abstract: An information processing device controls operation trouble or a calculation amount related to a machine interference check by automatically creating a three-dimensional model optimal for the machine interference check. The information processing device optimizes, for the interference check, three-dimensional model data of a machine including a plurality of structures. The information processing device includes a check object selection unit that performs selection among the structures, and a model creating unit that creates three-dimensional model data for an interference check which data includes the selected structure. Since the information processing device can generate three-dimensional model data optimized for an interference check, there is no trouble for a user to create new three-dimensional model data by himself/herself, and a simple and effective interference check can be realized.Type: GrantFiled: November 28, 2018Date of Patent: November 17, 2020Assignee: Fanuc CorporationInventors: Hiroaki Hada, Shinichirou Itakura, Kouji Satou

Patent number: 10310488Abstract: A numerical controller sequentially reads blocks contained in a machining program, analyzes the read blocks to identify a block that causes an alarm based on mismatch criterion information stored in advance, and generates alarm cause data. The numerical controller then generates, based on the generated alarm cause data, at least one set of proposal patch data for correcting the machining program in such a way that the cause of the alarm is solved and generates a corrected machining program that is the machining program to which the generated proposal patch data is applied.Type: GrantFiled: May 25, 2017Date of Patent: June 4, 2019Assignee: Fanuc CorporationInventor: Shinichirou Itakura

Patent number: 10120367Abstract: A numerical controller acquires state information (machine condition) such as the current temperature of a drive unit to determine whether a machining operation based on a machining program can be started or not by comparing the state information with a machine condition history recorded in a recording unit. If determined that the machining operation can be started, a machining operation start command is output and if determined that the machining operation cannot be started, the machine condition is monitored to withhold outputting of the machining operation start command until the machine condition allowing to start the machining operation based on the machining program appears.Type: GrantFiled: July 2, 2015Date of Patent: November 6, 2018Assignee: FANUC CorporationInventors: Shinichirou Itakura, Hideaki Maeda, Yorikazu Fukui
