Abstract
A method of milling a profile of a railway rail comprises: rotating a milling cutter including a plurality of face mounted cutting inserts mounted about a periphery thereof, milling a railway rail with cutting edges of the cutting inserts rotating in a predetermined plane corresponding to at least a portion of a desired rail profile while controlling the depth of cut of the cutting inserts; traversing the railway rail with the milling cutter while milling the railway rail and controlling the speed of traverse of the milling cutter along the railway rail.

A method of milling a profile of a railway rail comprising:
- rotating a milling cutter including a plurality of face mounted cutting inserts mounted about a periphery thereof;
- milling a railway rail with cutting edges of the cutting inserts rotating in a predetermined plane corresponding to at least a portion of a desired rail profile while controlling the depth of cut of the cutting inserts;
- traversing the railway rail with the milling cutter while milling the railway rail;
- and
- controlling the speed of traverse of the milling cutter along the railway rail.
An apparatus for milling at least a portion of a desired profile on a railway rail in situ, the apparatus comprising:
- a milling cutter including a cutter body comprising a cutter face, wherein the milling cutter is rotatable about a rotation axis;
- and
- a plurality of cutting inserts mounted around a periphery of the cutter face, the plurality of cutting inserts each comprising a cutting edge extending a distance from the cutter face to engage and mill a profile segment on the railway rail, wherein the rotation axis is substantially perpendicular to the plane of the profile segment to be milled on the railway rail by the cutting inserts.
