Publication number: 20120201622Abstract: An indexable cutting insert includes at least two side edges each defining an indexable edge of the insert and at least two cutting teeth are on each indexable edge. The cutting insert includes locating means on a plane of the upper face and/or a plane of the lower face. When mounted on a material removal tool, the locating means cooperate with receivers on the working face of the material removal tool to constrain degrees of freedom of the cutting insert. Further, the mounted cutting inserts each locate the radial edge of the cutting teeth in the active position on a common circumference of a circle centered on an axis of rotation of the material removal tool. A mounting system per see is also disclosed as well as a method of removing material from a workpiece with the material removal tool.Type: ApplicationFiled: October 14, 2010Publication date: August 9, 2012Applicant: SANDVIK INC.Inventors: Yevgeny Kocherovsky, Kenneth Noggle, Michael Charron

Publication number: 20120186386Abstract: A flywheel for use in an automobile between an engine and a clutch assembly is provided. The flywheel is a circular member having an engine side and an opposite clutch side. An aperture is formed in the circular member having an axis, and the aperture is used to operatively attach the flywheel to the engine. A plurality of clutch fins and/or grooves are formed on the clutch side adjacent the outer edge of the circular member and spaced radially about the axis of the aperture of the flywheel. The clutch fins have a face that is generally coplanar with the clutch side of the circular member. The fins and grooves work to cool the internal components of the engine. Optionally, a second set of grooves and fins may be formed on the engine side of the flywheel to further aid in cooling the clutch disc and other engine components.Type: ApplicationFiled: January 26, 2012Publication date: July 26, 2012Applicant: PRESTOLITE PERFORMANCE LLCInventor: Ross A.

Publication number: 20120182624Abstract: Disclosed is a lens wherein characteristic direction of aberration and the like can be easily determined, and a lens processing method. A reference point of the characteristic direction of aberration and the like is clarified by providing a thin portion (103) of a flange section (102) with a mark portion (106), and the characteristic direction of aberration and the like can be easily and accurately determined. Furthermore, by not removing the whole flange section (102) in the thickness direction, the center position of the lens is prevented from shifting at the time of attaching the lens (100), and the processing portion of the lens (100) can be prevented from hitting a case and the like at the time of transferring the lens (100).Type: ApplicationFiled: August 24, 2010Publication date: July 19, 2012Applicant: Konica Minolta Opto, Inc.Inventors: Takeshi Itou, Takayuki Kamikura

Publication number: 20120183363Abstract: End mills are disclosed which may be made monolithically of ceramic or other materials. The cutting portions of the end mills have lengths of cut that are no more than twice their cutting diameters and cores which are at least 0.7 times their cutting diameters. Their axial blades have cutting edges with negative radial rake and are separated by helical flutes. Their cutting ends have negative axial rake and are gashed ahead of center and have radial cutting edges with negative rake. Such end mills also have radiused corners and gashes transitioning from radial to axial at a flute. Methods of milling materials using such ceramic end mills are also disclosed.Type: ApplicationFiled: January 17, 2011Publication date: July 19, 2012Applicant: Kennametal, Inc.Inventors: Danny R.

Patent number: 8215883Abstract: To increase precision in straightness on a journal thrust surface relative to an outer peripheral surface of a journal in a crankshaft, a control system is provided for controlling movement of a cutter in axial directions by running a control program transferred from an automatic programming apparatus. The automatic programming apparatus corrects machining data on the basis of data for correcting the straightness gained through a comparison between results of a measurement of machining dimensions of the journal thrust surface in the workpiece on which a cutting process has been carried out and target machining dimensions for the journal thrust surface. A control program is prepared on the basis of the corrected machining data after correction of the machining data.Type: GrantFiled: August 10, 2007Date of Patent: July 10, 2012Assignee: Komatsu Machinery Corporation Ltd.Inventor: Takeshi Suzuki
