Patent number: 8033764Abstract: An indexable insert has one or more recesses formed in a frontside or backside surface which receives a surface of the head of a locking screw. When mounted, the insert is forced against respective support surfaces of an insert pocket. The locking screw is threaded into a counterbored tap hole to engage the insert and provide side locating forces and clamping forces to secure the indexable insert in the insert pocket. More particularly, the indexable insert has a shaped surface recess that mates to a complimentarily-shaped surface on the head of a locking screw and secures the indexable insert in multiple dimensions to a seating surface. A material removal tool and a method of mounting the indexable insert are also disclosed.Type: GrantFiled: July 31, 2009Date of Patent: October 11, 2011Assignee: Sandvik, Inc.Inventor: Kenneth G.

Patent number: 7390150Abstract: A cutting tool is provided and includes a plurality of cutting inserts located in respective insert pockets. The cutting inserts each include a top cutting plane with at least one cutting edge and a bottom support plane. The top cutting plane includes an engagement portion for mating with a respective engagement portion located in the respective insert pocket. A clamping wedge clamps the cutting insert against the respective insert pocket. A shear resistance created between the engagement portions of the cutting insert and the respective insert pocket during operation of the tool is greater than a centrifugal force created during operation of the cutting tool. In an exemplary embodiment, the engagement portions are shown as a plurality of serrations. The cutting tool is particularly useful in high speed milling operations.Type: GrantFiled: May 3, 2006Date of Patent: June 24, 2008Assignee: Valenite LLCInventors: Yevgeny Kocherovsky, Brian D.

Patent number: 6942432Abstract: A milling tool includes a milling body and a plurality of insert-carrying cartridges mounted in the milling body. Each cartridge includes front and rear side surfaces which oppose leading and trailing walls of a pocket formed in the milling body. The cartridge also includes inner and outer flank surfaces which interconnect the front and rear side surfaces. The body includes a slot which opens into the front side surface at a location intermediate the ends of the cartridge, to divide the body into a rigid base portion and an expandable portion. The base portion has a seat for a cutting insert. A threaded hole is formed in the slot intermediate the slot ends to receive a threaded wedge screw. Tightening of the screw causes the expandable portion to be expanded into contact with the leading wall of the pocket and thereby push the base portion into tight contact with the trailing wall of the pocket. Accordingly, the cartridge is secured within the pocket by a tight frictional contact which resists chatter.Type: GrantFiled: March 28, 2003Date of Patent: September 13, 2005Assignee: Sandvik Intellectual Property ABInventors: Kenneth G. Noggle, Lee Reiterman

Patent number: 6604894Abstract: A rotatable cutting tool has a shank portion for coupling to a tool driving device and a cutting portion in which are retained plural replaceable cutting inserts, each insert having at least one cutting edge. The shank portion includes a mounting face for removeably supporting an insert mounting disk having plural recesses at the periphery thereof for receiving the replaceable inserts. Each recess provides at least one seating surface for an insert, and includes opposing face portions between which an insert is releasably retained. The disk includes a central bore and radial grooves, at least one radial groove connecting the central bore and each insert receiving recess. The disk includes a concave central portion surrounding the central bore. A clamping means secures the disk to the shank and is used to elastically deform the concavity of the disk, whereby clamping forces are built and relaxed on all inserts placed in the disk concurrently by adjustment of the clamping means.Type: GrantFiled: March 8, 2002Date of Patent: August 12, 2003Assignee: Valenite Inc.Inventor: Kenneth G.

Patent number: 6336776Abstract: A fully indexable negative geometry polygonal insert uses an active cutting edge extending in a first direction from each corner of the polygon downwardly from an associated major polygonal surface of the insert along with a wiping or finishing cutting edge lying substantially in the plane of the associated major surface and extending in a second direction from the insert corner. The geometry of the cutting edge enables mounting of the insert to a milling cutter with negative axial rake, such that the cutting edge is substantially parallel to an axis of rotation of the cutting tool.Type: GrantFiled: December 16, 1999Date of Patent: January 8, 2002Assignee: Valenite Inc.Inventor: Kenneth G.

Patent number: 5320458Abstract: A cutting tool includes a rotary bar having an arcuate pocket in its side surface, and a segmental carrier arcuately slidable in the pocket to adjust the position of a cutting tip on a cutter blade. The carrier has a second arcuate pocket that slidably receives a segment-shaped shoe, such that the shoe can be arcuately adjusted to control or vary the back taper angle on the blade. The cutting blade is mounted flatwise on one face of the shoe, such that a corner tip on the blade projects beyond the profile of the rotary bar for use in reaming a hole in a workpiece. The adjustment axis of the shoe is coincident with the cutting tip on the reamer blade so that adjusting motions of the shoe do not disturb the position of the cutting tip achieved by arcuate adjustment of the carrier.Type: GrantFiled: May 24, 1993Date of Patent: June 14, 1994Assignee: Valenite Inc.Inventors: Lee Reiterman, Kenneth G.

Patent number: 5176477Abstract: A drill is provided having a generally cylindrically shaped body. The body has a rear end structured to releasably connect with a torque transmitting machine in a conventional manner. The body has a forward end which is provided with diametrically opposed seats. Each seat releasably retains a cutting insert. Each cutting insert has a cutting edge projecting forwardly from the forward end of the body. Further, the cutting inserts are oriented so that one cutting edge is at a ten degree positive lead angle and the other cutting edge is at a five degree negative lead angle, the angles being measured normal to the center line of the drill. In operation, the drill is used to provide a bore hole in a workpiece, the bore hole having a predetermined perimeter. As the rotating drill contacts the workpiece, the cutting edges contact the workpiece in a predetermined, progressive manner which thereby creates a plurality of spaced apart circular notches of differing depth in the workpiece.Type: GrantFiled: January 10, 1991Date of Patent: January 5, 1993Assignee: GTE Valenite CorporationInventor: Kenneth G.
