METHOD OF END MILLING OF FLAT SURFACES

摘要

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 Sand Slocated in milling plane on the condition of direction of feed vector Sinto billet body perpendicular to its end while feed vector Sat 90° to feed vector Sin direction opposite said primary rotary motion ?. Curvilinear penetration is performed at coordinated feeds Sand Sprovided 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.3 dwg
