Abstract: 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.

Abstract: A cutting tool has a cutter body, which carries a cutting insert, and an adapter, which has a longitudinal adapter axis, wherein a locking screw attaches the cutter body to the adapter. A coolant volume is defined in a vicinity of a meeting of the cutter body, the adapter and the locking screw. The adapter contains an axial adapter bore. The locking screw contains a transverse locking screw bore in fluid communication with the axial adapter bore. The locking screw further contains a peripheral transverse locking screw bore passage in fluid communication with the coolant volume and the transverse locking screw bore. The coolant volume and the transverse locking screw bore are in fluid communication with the cutter body coolant passage.

Abstract: A coupling system for mounting a cutting apparatus to a machine tool having a cutting apparatus and an adapter. The cutting apparatus has a first mounting flange having either a central bore or a central boss. The adapter has a second mounting flange having the other of a central bore or a central boss. The central boss on one of the mounting flanges forms a mating engagement with the central bore of the other mounting flange to align the two mounting flanges at a common center when the cutting apparatus is connected to the adapter. Additionally, each mounting flange may have at least one of a post or a groove located between an outer perimeter of the mounting flange and the central bore or central boss. When the cutting apparatus is connected to the adapter, at least one of the posts forms a mating engagement with a corresponding groove.

Abstract: A milling cutter 1 with a directed coolant delivery system is disclosed. The milling cutter 1 may have a plurality of coolant ducts 40 which span from a centrally located reservoir 42 or distribution point within the body 20 of the milling cutter 1 to a series of recesses 10 on the exterior of the body 20. Coolant nozzles 50 are inserted into a countersunk portion 51 between the coolant duct 40 and the recesses 10. The countersunk portions 51 provide protection for the coolant nozzles 50. Each coolant nozzle 50 has a bore 58 which may be narrower than the coolant duct 40 or alternatively may have a bore 58 and a restriction 60. Nozzles of the present invention provide consistent streams of coolant to the to the tool-workpiece interface to enable precise adjustment of the streams of a coolant from a position close to the tool-workpiece interface.

Abstract: An axial seating pin contacting and supporting an insert attached to a cutting tool body. The axial seating pin eliminates the need for forming an axial wall on the body of the cutting tool and contributes to the life of the cutting tool by providing a replaceable axial seating pin. The axial seating pin has a shank that slides into an aperture on the tool body and is then held to the body using a fastener.

Abstract: A toolholder for use in a metalworking operation, with a body extending along a longitudinal axis and a recess extending within the first end of the body. Adjacent an insert pocket adapted to receive a cutting insert in the recess is at least one wall with a portion having a surface with multiple interruptions to form a chip ejection segment. The chip ejection segment may be an integral part of the toolholder body or may be a discrete piece removably attached to the toolholder body. A method of imparting to a toolholder such a chip ejection segment is also disclosed.

Abstract: A cutting tool (10) having a body (12) with an axis (20). A pocket (22?)w having a primary bearing face (24) and a radial wall (26) formed on the surface of the body (12). An insert (28) is removably connected to the pocket (22?) at the primary bearing face (24) and is positioned adjacent the radial wall (26). An axial seating pin (32) is removably connected to the body (12) and extends at an angle substantially perpendicular to the axis (20) of the body (12). The axial seating pin (32) has an abutting face that contacts a face (30) of the insert (28) and prevents the insert (28) from moving axially during operation.

Abstract: The present invention is directed to a cutting insert with a rake face, a seating surface and a plurality of flank faces extending between the rake face and the seating surface. The intersection of the rake face and the plurality of flank faces define a plurality of cutting edges. The rake face of the insert has a plurality of corner regions formed at the intersection of side cutting edges to define corner cutting edges. The corner cutting edge in at least one corner region has a recessed profile when viewed from the side of the insert. The recessed profile has a concave shape and extends inwardly from the cutting edge. At the cutting edge, the recess has a conical shape to define a conical portion and further inward from the cutting edge the recess may have a cylindrical shape to define a cylindrical portion.

Abstract: A cutting insert comprises a rake face, a plurality of flank faces including clearance faces having a positive clearance angle. A cutting edge is formed at an intersection between the rake faces and the flank face and a convex wiper cutting edge formed on the cutting edge. A method for forming the cutting insert comprises the steps of placing a powdered material into a die and pressing the powdered material in the die to achieve a form having a convex portion on the rake face and at least one substantially flat clearance face having a positive clearance angle. Next, the form is removed from the die and sintered.
