Patent number: 7806634Abstract: 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: GrantFiled: December 22, 2008Date of Patent: October 5, 2010Assignee: TDY Industries, Inc.Inventors: Gilles Festeau, Jean-Luc Dufour, X.

Publication number: 20100202839Abstract: A double-sided cutting insert with a plurality of indexable convex cutting edges can have a top face and a bottom face, at least three convex cutting edges on each face connected by at least three nose corners, at least three peripheral side surfaces extending from each face toward a virtual middle plane; and a common lateral seating surface on each peripheral side surface. Each convex cutting edge can have at least a curved cutting edge region, and can further have a primary substantially straight cutting edge region intermediate the curved cutting edge region and the nose corner. Each peripheral side surface can further have a primary planar facet associated with the primary substantially straight cutting edge, and each face may also be single-handed in same direction.Type: ApplicationFiled: February 12, 2009Publication date: August 12, 2010Applicant: TDY Industries, Inc.Inventors: X.
