Patent number: 11933638Abstract: A method for detecting a phase on a gear includes obtaining a first determination result indicating whether the gear has been detected at a first detection position. A second determination result indicating whether the gear has been detected at a second detection position is obtained. A third angle between the first and second angles is obtained. A third determination result indicating whether the gear has been detected at a third detection position is obtained. The first angle is replaced with the third angle when the third and first determination results are same, or the second angle is replaced with the third angle when the third and first determination results are different. The phase on the gear is detected based on an angle that is between the first angle and the second angle.Type: GrantFiled: August 6, 2020Date of Patent: March 19, 2024Assignee: YAMAZAKI MAZAK CORPORATIONInventors: Kazuya Horibe, Kazumasa Maruta, Hiromasa Yamamoto, Yuki Yamamoto

Patent number: 7717018Abstract: A machining unit that is supported on a machine tool and machines a workpiece by a revolving tool with a main spindle section being driven and rotated includes an eccentric rotational section, a tool holder, a tool revolution-radius changing mechanism, and a cutting-edge-orientation correcting mechanism. The eccentric rotational section is disposed on the main spindle section, and is rotatable about an eccentric axis that is located eccentrically at any distance in a radial direction of the main spindle section from a rotation center of the main spindle section. The tool holder is disposed on the eccentric rotational section, and supports the tool. The tool revolution-radius changing mechanism moves the tool in the radial direction, and changes the radius of the revolution of the tool by rotating the eccentric rotational section about the eccentric axis.Type: GrantFiled: February 17, 2009Date of Patent: May 18, 2010Assignees: Sankyo Seisakusho Co., Ltd., Yamazaki Mazak Corp.Inventors: Heizaburo Kato, Minoru Kitayama, Kazuya Horibe, Hidekazu Kojima, Masaharu Nakatsu
