Patent number: 11281188Abstract: A controller for a machining-device includes a control-unit. The control-unit sequentially repeats a tapping step of tapping at a tapping-position by moving a tool from a retracted-position to a depth-position while rotating the tool in a normal direction, a retracting step of retracting the tool by moving from the depth-position to the retracted-position while rotating the tool in a reverse direction, and a positioning step of positioning a subsequent tapping-position. The control-unit performs a process including starting the positioning step at the same time as when the tool passes a reference-position in the retracting step, completing the positioning step at the same time as when the tool passes the reference-position in the tapping step, and controlling a timing at which acceleration of a workpiece and the tool finishes in the tapping step and a timing at which deceleration of the workpiece and the tool starts in the retracting step.Type: GrantFiled: September 8, 2020Date of Patent: March 22, 2022Assignee: FANUC CORPORATIONInventors: Naoya Takeuchi, Tetsushi Takahara

Patent number: 11048227Abstract: Provided is an abnormality detection device with which an abnormality of a machining state of a machine tool can be detected based on information on a section where machining is actually performed in machine tool-based machining. The abnormality detection device detects an abnormality of a machining state of a machine tool machining a workpiece with a tool. The machine tool includes a determination unit determining the machining state by using information related to an actual cutting section in the tool-based machining of the workpiece in the machine tool. The determination unit performs the machining state determination by using a deviation in position and length of a section recognized as the actual cutting section and a physical quantity in the actual cutting section acquired from the machine tool.Type: GrantFiled: March 22, 2019Date of Patent: June 29, 2021Assignees: FANUC CORPORATION, RICOH COMPANY, LTD.Inventors: Tetsushi Takahara, Yasuhiro Nakahama, Shinji Okuda, Junichi Takami
