<p><P>PROBLEM TO BE SOLVED: To manufacture kinds of spiral bevel gears by using tools as few as possible. <P>SOLUTION: The bar cutter head 20 for receiving a plurality of bar cutters of a first bar cutter set comprises n receiving opening parts 25.1-25.6 for receiving n bar cutters of the first bar cutter set. The n receiving opening parts are all arranged along a circle which is a concentric reference of a first cutter head and has a radius r1 of the reference of the first cutter head. Accordingly, milling of a first spiral bevel gear can be performed in a single indexing method. The bar cutter head 20 further comprises at least m receiving opening parts 26.1-26.6 for receiving m bar cutters of a second bar cutter set. The m receiving opening parts are all arranged along a circle which is a concentric reference of a second cutter head and has a radius r2 of the reference of the second cutter head. Accordingly, milling of a second spiral bevel gear can be performed by using the m bar cutters. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
