??MP-2021 ADJUSTABLE AXIAL AND RADIAL LOCATING WEDGE ASSEMBLIES FOR AN INDEXABLE INSERT CUTTING TOOL ABSTRACT OF THE DISCLOSURE A milling cutter which is adapted to be rotated about a central axis includes at least one as well as a rear wall. An indexable insert having front and rear planar surfaces is receivable in the insert pocket, along with at least one locking wedge, which is interposed between the insert and the pocket walls for securing the insert within the pocket. In accordance with the subject invention, an adjustable locating wedge is provided for regulating the axial location of the insert. The locating wedge, a portion of which is disposed in abutting relationship with the axially lowermost cutting edge of the insert, is received within a groove located in the rear wall of the insert pocket. The receiving groove is aligned with the insert and extends radially inwardly from the periphery of the cutter body. In addition, the receiving groove is disposed at an angle relative to the rear wall of the insert pocket such that as the position of the adjustable locking sedge is varied within the groove, its axial position relative to the cutter body is also varied. By this arrangement, the axial position of the insert, which resets on the locating wedge, can be adjusted. More specifically, as position of the locating wedge is varied within the groove, its axial position is varied, thereby varying the axial position of the insert. In a preferred embodiment, an adjustable insert seat is provided to vary the radial position of the insert.
