Abstract
A tool has a tool body which defines a first seat into which is secured an anvil. The anvil and the tool body define a second seat into which a backup plate is located. The backup plate has a longitudinally extending groove which is used to locate a form tool cutting insert. A first clamp assembly exerts a clamping force on the insert and backup plate against the anvil in a first direction. A second clamp assembly exerts a clamping force on the insert and backup plate against the anvil in a second direction, the second direction being approximately 90.degree. to the first direction. The insert has a cutting surface of a predetermined configuration on two opposite sides such that indexing of the cutting insert 180.degree. will position the opposite cutting surface in the machining ready position. The backup plate has a complementary predetermined configuration to support each of the cutting surfaces of the insert. The clamping of the insert and backup plate against the anvil in two directions approximately 90.degree. apart, enables a more accurate positioning of the insert and reduces the need for running set-up parts after each insert change or indexing.
