Abstract
A method and apparatus are provided for manufacturing or machining a gear workpiece with a hyperboloidally, globoidally or similarly formed gearlike tool which has an abrasive or similar surface. The axes of the workpiece and tool are skew lines. During changing of the center distance, in particular as the workpiece and tool are moved apart at the end of the machining operation, the crossed-axes angle is automatically adjusted to conform to the effective rolling circle.
