摘要： An indexable insert for application to turning of a cast iron product, including a first minor cutting edge 21 having a radius Ra and a second minor cutting edge 22 having a radius Rb successively provided between an arcuate nose cutting-edge 12 having a nose radius R and a linear cutting edge 16 so as to extend from the nose tip to the linear cutting edge 16. At a connection point P1 between the arcs assumed by the cutting edges 12 and 21, a smaller intersectional angle &thgr;x of a tangent T12 and a tangent T21 to the respective arcs is 1° or less. Also, at a connection point P2 between the arcs assumed by the cutting edges 21 and 22, a smaller intersectional angle &thgr;y of the tangent T21 and a tangent T22 to the respective arcs is 1° or less. The radii R, Ra, and Rb are set to the dimensional relationships “Ra>R, Ra falls within a range of 3 mm to 20 mm, and Rb≧1.5Ra.”

摘要： A cutting insert has a generally parallepipedal body formed with a pair of generally rectangular, planar, and parallel side faces, a mounting formation at at least one of the side faces, a pair of opposite edge faces between the side faces and each forming at each end of the body a cutting face bounded by a cutting edge, and a respective pair of at least partially circularly arcuately concave free faces at each end extending between the respective cutting edges. The cutting edges are arcuate and each cutting edge has a convex part and straight or concave part.

摘要： A rhombic shaped metal cutting insert is adapted for longitudinal turning and copy turning. Opposing nose corners of the insert form equal angles less than 60 degrees. A pair of side cutting edges converge toward each of the nose corners. The side cutting edges of each pair form obtuse angles with respective side cutting edges of the other pair. A longest diagonal extending through the insert intersects both of the nose corners and forms an acute angle relative to a diagonal which bisects both of the obtuse angles. Each nose corner has a corner cutting edge formed by a plurality of curved segments. First and second ones of those segments are disposed on opposite sides of the longest diagonal and together form an angle of about 90°. Situated between the first and second segments is a third segment which is intersected by the longest diagonal. Adjacently disposed ones of the curved segments at each corner have radii that are different from one another.
