摘要： An indexable cutting insert has upper and lower surfaces with a peripheral surface extending therebetween and having four side surfaces alternating with four corner surfaces. The side and corner surfaces intersect the upper surface to form side and corner cutting edges, respectively. Each side cutting edge includes a primary cutting edge adjoining one of the corner cutting edges at a first endpoint and a secondary cutting edge adjoining another one of the corner cutting edges at a second endpoint. In a top view, the four primary cutting edges define an imaginary first square, each primary cutting edge is tangential to its adjoining corner cutting edge, and each secondary cutting edge is curved and entirely located in one of four imaginary quadrants. The insert is removably secured in a rotary cutting tool such that one of the secondary cutting edges contains the axially forwardmost point of the insert's upper peripheral edge.

摘要： A double-sided tangential cutting insert comprising a pair of cutting rake faces, a pair of major side surfaces and a pair of opposing minor side faces each having a twisted convex shape. Each of the cutting rake faces is defined between a pair of main cutting edges, a pair of full nose cutting edges, and a pair of opposing convex minor cutting edges. Each of the minor side faces is defined between one of the convex minor cutting edges at one of the rake faces and one of the convex minor cutting edges at the other one of the rake faces wherein, at each minor side face, a ridge line interconnects an apex of the convex minor edge at the one of the rake faces and an apex of the convex minor cutting edge at the other one of the rake faces. Other variants and embodiments are broadly contemplated herein.

摘要： A cutting tool for simultaneously forming grooves and face surface features on the face of a golf club head, and methods of using said cutting tool, is disclosed herein. The tool preferably includes at least one groove cutting portion, which creates a groove having a sidewall angle, at least one radius cutting portion, which creates each groove's edge radii, and at least one face cutting portion, which flattens and/or textures the landing area disposed between each pair of grooves and is wider than the at least one groove cutting portion. The cutting tool of the present invention preferably spins around an axis parallel to the golf club face, and can include one or more micro-feature forming portions to create positive and/or negative texturing in the land areas between each pair of grooves.

摘要： A cutting insert has polygonal first and second end surfaces which are connected by a peripheral side surface, each end surface defining first and second end planes, respectively. The peripheral side surface has first peripheral side portions alternated in the circumferential direction with second peripheral side portions. The first peripheral side portions are inverse copies of the second peripheral side portions. Each peripheral side portion includes first and second sub-faces which form different angles with the first and second end planes. The first and second sub-faces intersect one another between the first and second end planes to form a line which is parallel to the first and second end planes.

摘要： In a cutting insert according to an embodiment, an upper cutting edge includes, sequentially from a first corner to a second corner, a corner cutting edge, a minor cutting edge inclined as separating from the corner cutting edge at a first inclination angle on a basis of a vertical plane perpendicular to a central axis extending between upper and lower surfaces, and a major cutting edge inclined as separating from the minor cutting edge at a second inclination angle on the basis of the vertical plane so as to become more closer to the lower surface than the minor cutting edge. A cross section of a rake surface obtained by cutting an inwardly located end portion thereof along a direction of the central axis has a straight line shape or concave shape in a region crossing over at least a minor rake surface and a major rake surface.

摘要： The present invention relates to the cutting insert having a cutting edge which has a corner section that forms a convex arc shape when seen in a planar view from direction facing the rake face and a linear section that is in contact with the corner section at least at one end of the corner section and extends linearly. The cutting edge is provided with a first region along the corner section when seen in a planar a second region along the linear section and a third region between the first region and the second region. A rake angle of the cutting edge in the third region is made greater than rake angles of the cutting edges in the first region and the second region.

摘要： A cutting insert with a serrated topography includes a top surface terminating in a circular cutting edge, a bottom surface and a frusto-conical sidewall interconnecting the top surface and the bottom surface, and a plurality of serrations on the top surface uniformly disposed around the circular cutting edge and extending radially inward from the cutting edge in such a way that a bisector through each serration passes through a central axis of the cutting insert. The plurality of serrations are positioned in a cutting tool in such a way so as to reduce regenerative chatter during a cutting operation. A method of reducing generative chatter by positioning the cutting inserts in a particular fashion in a cutting tool is also disclosed.

摘要： A milling cutter for chip removing machining, including a basic body rotatable in a predetermined direction around a center axis and having a front end surface and an envelope surface that extends axially backward from the front end surface and is concentric with the center axis. A number of indexable milling inserts are mounted in respective peripherally spaced-apart seats having a mutually fixed pitch, each milling insert including an upper side, an under side and at least one clearance surface, the clearance surface together with the upper side delimiting at least two alternately active cutting edges that are uniform in their extension between first and second end points. The cutting edges of each milling insert are situated on different levels in relation to the under side of the milling insert to alter the effective pitch between the active cutting edges of the milling inserts by indexing of at least one of the milling inserts.
