Publication number: 20120087746Abstract: A cutting tool comprises a cutting insert, a tool holder, and a fastener. The cutting insert comprises a cutting edge and a fastener bore adapted to accept a fastener for fastening together the cutting tool and tool holder. A coolant flow recess in the fastener bore is adapted to direct coolant though the coolant flow recess and toward a head portion of the fastener. The tool holder comprises an insert pocket adapted to removably fasten the cutting insert and fastener to the tool holder, and a coolant bore adapted to direct the coolant from the tool holder to the coolant flow recess of the fastener bore. The head portion of the fastener and the coolant flow recess of the fastener bore define a gap that directs the coolant to the cutting edge of the cutting insert.Type: ApplicationFiled: October 8, 2010Publication date: April 12, 2012Applicant: TDY Industries, Inc.Inventors: X.

Patent number: 8147992Abstract: The present invention relates to ceramic cutting tools, such as, an aluminum oxide with zirconium oxide ceramic cutting tool with diffusion bonding enhanced layer and CVD coatings, particularly useful for machining modern metal materials. The method comprises a chemical reaction with a mixture including nitrogen and aluminum chloride introduced to form a diffusion bonding enhanced layer between the ceramic substrate and the CVD coatings. Thus formed diffusion bonding enhanced layer is highly adherent to the aluminum oxide with zirconium oxide ceramic substrate and significantly enhances the CVD coating properties, thus improving the machining performance in terms of the tool life of zirconium-based aluminum oxide with zirconium oxide ceramic cutting tools.Type: GrantFiled: March 9, 2009Date of Patent: April 3, 2012Assignee: TDY Industries, LLCInventors: X.

Publication number: 20110250025Abstract: A cutting insert for milling operations, such as, face milling, slot milling, plunge milling, and ramping operations. The cutting insert exhibits a combination of favorable cutting edge strength, and unique cutting edge geometry, thus, allowing milling operations at relatively high feed rates. The cutting insert includes at least four cutting edges, wherein at least one of the cutting edges is a convex cutting edge. Certain embodiments of square cutting inserts will have four convex cutting edges which may be connected by nose corners. The convex cutting edge may comprise at least one of a circular arc, a portion of an ellipse, a portion of a parabola, a multi-segment spline curve, a straight line, or combinations of these. Wherein the convex cutting edge comprises a circular arc, the circular arc may have a radius greater than or equal to two times a radius of the largest circle that may be inscribed on the top surface.Type: ApplicationFiled: June 24, 2011Publication date: October 13, 2011Applicant: TDY Industries, Inc.Inventors: GILLES FESTEAU, Jean-Luc Dufour, X.
