WOOD-MILLING CUTTER Russian patent published in 2012 - IPC B27G13/08 B23C5/20 

FIELD: process engineering.

SUBSTANCE: proposed cutter comprises body, cutting blades, split resilient-deformable wedges and screws. Two-blade cutters feature rear angle sharpening smaller than half the recommended amount while that of face angle exceeds said amount. Said mill has its blades turned through the angle required for cutting geometry and planar contact between blade rear thrust surface and body seat thrust base surface. Blade geometrical parameters are defined by relationship H=2·R·sin(γ+α/2), where H and R are blade face surface width and radius, respectively, γ and α are face and rear angles.

EFFECT: ease of manufacture, shorter preparation of mill for cutting.
