International ClassB23C 005/20AbstractA dove-tail end mill having a cutter shank with a milling head supporting a plurality of replaceable standard 60° triangular cutter inserts. The cutter inserts are designed and oriented with respect to the cutter head to position cutter edges for generating the inclined undercut surface of a dove-tail slot. Simultaneously, the cutter configuration is designed to establish a clearance angle between the lower cutting edge of each of the cutters and the planar surface being generated by the cutter inserts. The milling head defines a plurality of cutter stations each having planar support surfaces for stabilization of the respective cutter inserts and cutter orientation shoulders for accurate positioning of each of the cutter inserts with respect to the cutting head. The cutting head supports each of the cutter inserts to define a cutting rake of about plus 15° and axial rake of about plus 10° and a radial rake of about minus 14°.Field of SearchPlural simultaneously usable separable tools in common seat or common clamp actuator for plural simultaneously usable toolsWith separate means to fasten tool to holder Apertured tool With separate means to fasten tool to holder Wedge clamp element Having peripherally spaced teeth Plural spaced seats and common holder Apertured tool With means projecting through aperture to force tool laterally against reaction surface Tilting clamp element and separate means to tilt same INCLUDING TOOL HAVING PLURAL ALTERNATIVELY USABLE CUTTING EDGES Plural simultaneously usable separable tools in common seat or common clamp actuator for plural simultaneously usable tools Face or end mill With cutting edge entirely across end of tool (e.g., router bit, end mill, etc.) Face or end mill | |
