Patent number: 10029318Abstract: A milling cutter is composed of a tool body having an approximately cylindrical or disk-like shape and a plurality of edge portions provided on at least an outer peripheral portion of one end of the tool body at predetermined intervals along a circumferential direction. The edge portion has a major cutting edge and a minor cutting edge that perform an operation of cutting a workpiece, the major cutting edge is positioned outside the minor cutting edge in a radial direction, and the minor cutting edge has a cutting edge angle that is an angle with respect to a plane orthogonal to a center axis of the tool body and set so as to be an elevation angle open outward in the radial direction. When surface machining is performed on a workpiece with the milling cutter, a high degree of machined surface accuracy equivalent to that obtained by grinding is obtained.Type: GrantFiled: December 4, 2015Date of Patent: July 24, 2018Assignees: DMG MORI CO., LTD., Intelligent Manufacturing Systems International, Advanced Research for Manufacturing Systems, LLCInventors: Hidenori Saraie, Eisaku Ueda, Masaya Nishimoto, Kazuo Yamazaki, Masakazu Soshi

Patent number: 9889888Abstract: A vehicle side body structure is provided, which includes a hinge pillar having inner and outer hinge pillar members forming, in a vehicle side part, a closed section space extending in vehicle vertical directions, a side sill having a member forming, on a rear side of the hinge pillar, a closed section space extending in vehicle longitudinal directions, and a closed section space component forming a closed section space extending continuously in the longitudinal directions along an outer surface of the inner hinge pillar member and connecting to the closed section space of the side sill on the rear side. The inner hinge pillar member is formed with a bend-facilitating portion adjacently disposed on the front side of a front end of the closed section space component, extending vertically continuously or intermittently, and protruding outwardly due to a stress concentration by a frontal impact load applied to the hinge pillar.Type: GrantFiled: April 24, 2017Date of Patent: February 13, 2018Assignee: Mazda Motor CorporationInventors: Takashi Narahara, Masaya Nishimoto, Nobuhiko Yokoyama, Shuichi Nakagami
