    摘要: A cutting insert for chip forming machining comprises an upper rake face, a lower face, and an edge clearance face interconnecting said upper and lower faces. The edge clearance face includes a step located intermediate the upper and lower faces. The step defines a fracture zone so that in the event of insert breakage, the location of the breakage can be controlled. The portion of the insert located below the step defines, in effect, an integral shim.

    摘要: A cutting insert includes a first mounting surface, a second mounting surface located on an opposite side of the insert from the first mounting surface, and a first side surface disposed between the first mounting surface and the second mounting surface. The insert further includes a first groove extending substantially diagonally across the first side surface and dividing the first side surface into discrete, separated, triangular first and second first side support surfaces. The first and second first side support surfaces are each bounded along first and second edges thereof by rake surfaces forming non-zero angles with the first and second side support surfaces and along third edges thereof by the groove.

    摘要: The present invention relates to an indexable cutting insert for an end mill for machining of contours in a workpiece and to a milling tool. The cutting insert is asymmetrical in respect of a line through a hole in the cutting insert. The cutting insert includes two cutting edge portions. Each cutting edge portion comprises of a substantially straight cutting edge and a curved cutting edge along respective intersecting lines between a clearance surface and a chip surface. The curved cutting edges have different lengths. The cutting insert includes recesses in a bottom side of the cutting insert. The recesses are arranged on both sides of and at different distances from the hole of the cutting insert.
