Cutter with positive seated stick blades for bevel gear cutting

A gear cutting tool comprising:

• a cutter head having an axis of rotation, a first side and a second side spaced axially from one another, at least one rectangular cutting blade mounting and positioning slot arranged in said cutter head and having a length extending from said first side to said second side, said at least one slot comprising a radial seating surface for providing precise and stiff radial positioning of the blade and a tangential seating surface for backing the blade up against the main cutting force, said radial and tangential seating surfaces being arranged perpendicular to one another,
• an angular clamp block located in said at least one slot,
• a cutting blade having a square or rectangular cross-section positioned in said at least one slot, said clamp block contacting a corner region of said cutting blade, said corner region being remote from said radial seating surface and said tangential seating surface of said at least one slot,
• at least one clamp screw positioned in said cutter head at each of said at least one slot, said at least one clamp screw exerting a clamping force against said clamp block and said cutting blade,
• whereby a first portion of the clamping force is directed to and effects a clamping of the cutting blade against said radial seating surface and a second portion of the clamping force is directed to and effects a clamping of the cutting blade against said tangential seating surface, and wherein the cutting blade is adjustable radially by axial movement by a non-self-locking system.
