Abstract:
1. A milling tool formed for the hobbing of a workpiece having cogs comprising a cylindrical tool body that defines a rotation axis (C 1 , C 3 ) and comprises a plurality of disc-shaped segments each one of which includes a hub part having two opposite plane-parallel end surfaces that extend perpendicular to the rotation axis (C a peripheral cam for a plurality of tangentially spaced-apart milling inserts, wherein bordering disc-shaped segments are detachably interconnected by means of one each of male and female members co-operating in pairs, wherein the male and female members are situated so that the rotation axis (C wherein the male and female members include each a contact surface, which converges from a big end toward a small end and which, in a cross-section across the rotation axis, forms an out-of-round curve, the contact surfaces of the male and female members being dimensioned so that they, when the male and female members are being brought together, direct their two bordering segments toward an end position that is centred and mutually angularly determined by the out-of-round cross-section curve around the rotation axis (C
