Patent number: 8613574Abstract: A cutting tool having an outer surface with a plurality of inserts connected to a distinct pocket extending generally radially on the outer surface. The cutting inserts are arranged in a helical array on the outer surface in a manner that at least one cutting edge of each cutting insert is spaced in an angular circumferential direction from the pocket of the next adjacent cutting insert. The spacing of the inserts is such that a distinct point on the each one of the one or more cutting edges define part of a layout line having a non-uniform slope.Type: GrantFiled: February 22, 2008Date of Patent: December 24, 2013Assignee: Kennametal Inc.Inventors: James M.

Patent number: 7753625Abstract: An indexable, helical cutting insert has multiple cutting edges. In tone configuration, the cutting insert includes four helical cutting edges. In another configuration, the cutting insert includes eight helical cutting edges. In any configuration, the cutting insert may include at least one axial clearance slash extending from a bottom surface to one of the side walls forming a wiper on an edge of the axial clearance slash. In any configuration, the cutting insert may include at least one inside cutting edge that extends outwardly a distance from the side wall. The helical cutting insert may also include at least one progressive cutting edge and/or at least one helical cutting edge that is curved inwardly to enable the cutting insert to perform machining operations on cutters having different diameters.Type: GrantFiled: June 13, 2005Date of Patent: July 13, 2010Assignee: Kennametal Inc.Inventor: Karen A.

Patent number: 7597509Abstract: An insert retention screw having a head with a radius that is sufficient size to fit within a mounting hole of a cutting insert and seat within a seating plane within the mounting hole that is generally perpendicular to the axis of the insert when the screw is at an angle of about 0-15 degrees is disclosed. The retention screw provided for holding a cutting insert in the pocket of a tool body. The pocket is partially defined by a floor and a seating surface. A threaded hole is at an angle that is taken with reference to the pocket floor. The insert has a mounting hole passing therethrough. The retention screw passed through the mounting hole and threads into the threaded hole so as to draw the insert against the seating surface.Type: GrantFiled: May 3, 2006Date of Patent: October 6, 2009Assignee: Kennametal Inc.Inventors: Glenn W. Sheffler, Jeffrey F. Kovac, Kevin M. Gamble, Karen A. Craig

Patent number: 7510352Abstract: An integral insert clamping mechanism for transferring clamping forces away from the screw hole of the insert to relieve stress at the screw hole by way of protrusions located on the bottom surface of the clamp plate. The clamping mechanism functions by a clamp plate being seated within an indentation on the top surface of the insert and a screw inserted into screw holes of the clamp plate and the insert and then threadably engaged with a threaded bore of a milling cutter. The top surfaces of the screw, the insert and the clamp plate being substantially coplanar. In an alternative embodiment, the clamp plate having a chip breaker.Type: GrantFiled: August 3, 2007Date of Patent: March 31, 2009Assignee: Kennametal Inc.Inventors: Karen A. Craig, Thomas J.

Patent number: 7399146Abstract: A rotary cutting tool such as a helical end mill, having pockets arranged to overcome harmonic vibrations. The tool has at least two and in one embodiment all three of three spacing irregularities. In the first irregularity, columns of pockets, typically associated with flutes, are staggered circumferentially out of even spacing. In a preferred embodiment having three flutes, the flutes are mostly not centered on one hundred twenty degree intervals. In the second irregularity, at least some pockets are arranged at different radial rake angles. In the third irregularity, at least some pockets are arranged at different axial rake angles.Type: GrantFiled: September 29, 2003Date of Patent: July 15, 2008Assignee: Kennametal Inc.Inventors: Thomas J.

Patent number: 7357604Abstract: An indexable cutting insert includes a first component with an outer or top surface and side surfaces. A third component is mirror symmetric with respect to the first component about a vertical or y-axis of the cutting insert. A second component is disposed between the first and third components. Multiple cutting edges are defined at an intersection between the side surfaces and the top surface, wherein the cutting edges define a positive axial rake angle. In one embodiment, the first and third components are in the shape of a polygonal with a star appearance, and the second component is in the shape of a square. The first and third components are offset from one another by a first offset angle, while the second component is offset from the first and third components by a second offset angle to allow the cutting insert to be indexable.Type: GrantFiled: June 20, 2006Date of Patent: April 15, 2008Assignee: Kennametal Inc.Inventor: Karen A.
