METHOD FOR MACHINING ROTOR EQUIPPED WITH INTEGRAL BLADE

PROBLEM TO BE SOLVED: To provide a method for machining a semi-processed product by a rotary tool 20 such as a cutter provided with an integral blade or an insert, to obtain a rotor 10 integrally provided with a series of blades 12 and 13. SOLUTION: In this method, a step (a) for forming the series of blades 12 and 13 by forming a series of cavities 14 and 15 on the semi-processed product by the rotary tool 20 such as an integral blade or an inserted edge, etc is included. In this step (a), a step (b) for forming a hole 17 in the semi-processed product and a step (c) for eliminating a material from the semi-processed product by advancing the rotary tool 20 along the rotary axis are included. The rotary axis of the rotary tool 20 is centrally dislocated from an axis of the hole 17. COPYRIGHT: (C)2006,JPO&NCIPI
