A built-up fraise to cut a screw-compressor rotor is proposed. The fraise is composed of a number of blades and a cutter head. Each blade is cut out from a tempered planar plate of high speed tool steel by wire-cut electrodischarge machining. During the machining, the wire electrode has a fixed angle to ensure both the side and the end relief angles of a cutting edge, so that the rake face regrinding sharpens the cutting edge without changing the profile of the rake face. The cutting edge profile of fraise is calculated from the surface of revolution, which is an ideal tool surface. The ideal surface is determined by female rotor tooth profile expressed in numerical formula. A fraise for male rotor and that for female rotor was made on an experimental basis, and a set of rotor was made using the fraises.
