  • Publication number: 20220250171
    Abstract: A rotary cutting method includes producing a processed product by rotary cutting of a workpiece by a rotary tool. The rotary tool has at least one cutting edge of which both of a first rake angle in a rotation radial direction and a second rake angle in a rotation axis direction are negative. The at least one cutting edge has a slanted face connected with a rake face forming the first and second rake angles. The slanted face is connected with the rake face at a ridge line. The slanted face faces a rotating direction of the rotary tool. An angle of the slanted face to the rotation axis direction is positive.

  • Patent number: 11203063
    Abstract: Crack-free powder-based, near net shaped parts are fabricated using a die assembly and cold isostatic pressing. Soft materials are introduced on both sides of die components in order to balance compression loads applied to the die component, and thereby avoid deformation of the die component.

  • Publication number: 20030155407
    Abstract: In the process for the monolithic molding of superplastic material, generation of wrinkles on the molded product can be prevented by avoiding local expansion generated in the no-bonding regions of both of three or more metal plates when the metal plates are monolithically molded by means of superplastic molding. The process is characterized in that auxiliary plates for molding are placed on both sides of the superposed plates through the no-bonding regions, these plates are set in the molding die, and a pressure lower than applied to the non-bonding regions is applied to spaces between inner wall of the molding die and the auxiliary plates to control movement of the top and bottom.
