<p>An adjustable insert cutting angle cutting tool (20) comprising a tool holder (24) having a cartridge receiving pocket (32), an insert cartridge (22) clamped in the cartridge receiving pocket (32) by a clamping member (26), and a cutting insert (28) removably retained in the insert cartridge (22). The clamping member (26) is operated by a separate fastening member (36). The cutting insert (28) has at least one operative cutting portion (30), and the insert cartridge (22) is oriented in a cartridge receiving pocket (32) of the tool holder (24) so that the operative cutting portion (30) encounters a workpiece (34) at an insert cutting angle (al). The clamping member (26) has a clamping surface (52) with at least one clamping zone (Czl), and the same at least one clamping zone (Czl) makes contact with a nonplanar clamped surface (54) of the insert cartridge (22) for different values of insert cutting angle(al). The insert cutting angle (al) is increased or decreased by reorienting the insert cartridge (22) in the tool holder (24), following release of the fastening member (36).</p> |
