Patent ID: 7584735

Claim:
A process for chip-forming machining of thermally sprayed cylinder bores of a cast cylinder crankcase, in which those surfaces of the cylinder bores that are to be thermally coated are roughened, the cylinder bores are coated by a thermal spraying process, and the cylinder bores are remachined to their final dimensions, comprising: providing a milling cutter, and machining at least one of a surface of an insertion bevel, a surface of an end bevel, a cylinder head sealing surface, a crankshaft space surface, and a cylinder bore surface in a chip-forming manner by guiding said milling cutter so that respective cutting edges of teeth on the milling cutter engage and penetrate into material that is to be removed in a direction approximately orthogonal to said at least one surface from the outside so as to minimize detachment of material coating said at least one surface.
