<p>Disclosed are a method and a bar blade (10) for milling spiral bevel gears and hypoid gears. One end (14) of a shaft (12) of said bar blade (10) has a blade profile that is formed by the cross-section of at least one cutting area (24), at least two free areas (17, 19), and at least one top area (21). In order to create a tooth space, the blade profile is provided with a first cutting edge (16) for a first flank, a second cutting edge (18) for a second flank that faces the first flank, and a top cutting edge for the bottom of a tooth space. The first and the second cutting edge (16, 18) are embodied as principal cutting edges for completely cutting the first or second flank. The top cutting edge (20) is configured for completely cutting the bottom of the tooth space such that the tooth space comprising the complete final geometry is created in one milling process by means of one and the same bar blade (10). Due to the fact that the bar blade (10) performs the function of an external blade and an internal blade, the number of the cutting edges actively involved in creating a tooth space can be doubled while using the same milling head.</p> |
