A floating wedge is described for facilitating the mounting of an indexable insert in a pocket of an indexable cutting tool. The floating wedge includes a main body member having opposed leading and trailing surfaces and a swivel plate member having opposed leading and trailing surfaces. The leading surface of the main body member and the trailing surface of the swivel plate member are disposed in abutting relationship and are provided with complementary configurations, thereby enabling the relative slidable movement between the members such that orientation of the leading surface of the swivel plate member relative to the trailing surface of the main body member may be adjusted. The adjustability between the members enables full and equal contact pressure to be established between the floating wedge, the indexable insert and the walls of the insert pocket, thereby eliminating localized stresses and preventing insert failure. In a preferred embodiment of the subject invention, the trailing surface of the main body member and the associated wall of the pocket of the cutting tool are provided with complementary configurations. The latter arrangement allows for the relative movement between the leading surface of the swivel plate member and the walls of the insert pocket, thereby increasing the range of motion of the floating wedge. |
