Patent number: 12370621Abstract: A friction stir tool control method is a control method for controlling an operation of a friction stir tool by supplying a necessary drive electric current to a drive source of the tool. The control method includes obtaining a pressurizing force change ratio by comparing a set pressurizing force predefined as a pressurizing force at plunging of the tool into a workpiece with an actual pressurizing force occurring at actual plunging of the tool into the workpiece by supplying a drive electric current for generating the set pressurizing force to the drive source. The drive electric current is regulated in accordance with the pressurizing force change ratio so that the actual pressurizing force comes to the set pressurizing force, and the drive source is driven with the regulated drive electric current.Type: GrantFiled: February 7, 2022Date of Patent: July 29, 2025Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Masahiro Miyake, Takuya Fukuda, Tadahiro Edagawa, Yoshitaka Muramatsu, Norichika Kita, Makoto Tsujinaka
