Usage of method and the bar condition cutting blade and that kind of bar condition cutting blade in order the milling cutter to cut the spiral bevel gear and the hypoid gear

摘要

Method and the bar condition cutting blade in order the milling cutter to cut the spiral bevel gear and the hypoid gear (10) is offered. It possesses the cutting blade contour which is demarcated the bar condition cutting blade (10) the shank (12) one end (14), at least one face (24), at least two flanks (17 and 19) and the top face (21) by the intersection part. In order to form the tooth space, the cutting blade contour has, the 1st cutting edge for the dedendum flank 1st (16) with, the 2nd cutting edge for the dedendum flank 2nd opposes to the dedendum flank 1st (18) with, the top face cutting edge for bottom of the tooth space (20) with. The 1st and 2nd cutting edge (18), it is constituted as the main cutting edge which cuts the 1st and 2nd dedendum aspect completely. The top face cutting edge (20), it cuts the bottom of the tooth space completely. Therefore, making use of equality and the single bar condition cutting blade (10), it depends on the milling cutter cutting pass of 1 times, to cut to process to final geometric form it is possible the tooth space. The bar condition cutting blade (10), from the fact that functioning it does, making use of the identical cutting head as both of the inside cutting blade and the outer part cutting blade, it is possible to redouble the number of cutting edges which participate in cutting of the tooth space.
