METHOD OF END MILLING OF FLAT SURFACES Russian patent published in 2013 - IPC B23C3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for milling of flat surfaces. Proposed method comprises using the end mill to be brought in touch with the end of machined surface. Primary rotary motion and curvilinear penetration in billet are imparted to cutter with two feed motions S_x and S_y located in milling plane on the condition of direction of feed vector S_y into billet body perpendicular to its end while feed vector S_x at 90° to feed vector S_y in direction opposite said primary rotary motion ω_v. Curvilinear penetration is performed at coordinated feeds S_x and S_y provided that cutter penetration path represents a quarter of ellipse with its larger axis being equal to cutter diameter while smaller axis is defined by cited relationship.

EFFECT: higher durability.
