Title:

METHOD OF SURFACE MACHINING OF HOT ROLLED STEEL MATERIALS AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/1997/003778

Kind Code:

A1

Abstract:

According to the invention, when upper and lower surfaces of a hot sheet material are to be machined by rotation of milling cutters, which interpose the hot sheet material from above and below, while the hot sheet material runs, a cutting resistance determined by a kind of the hot sheet material and a cutting condition including temperatures at the time of machining and depth of cut is controlled through adjustment of the depth of cut, and the hot sheet material is machined while breakage thereof is prevented with tension caused in the hot sheet material by the cutting resistance kept smaller than a breaking strength of joined portions of the material.
