Abstract
The invention concerns a method of machining the tooth flanks of substantially cylindrical, but crowning-modified gears through a diagonal generating process employing a worm-shaped tool which is modified with a crowning in the direction of its rotary axis, wherein the crowning can be positive or negative (concave crowning), wherein by matching the crowning of the tool to the diagonal ratio, a flank twist is generated by means of the tool and superimposed on the natural flank twist, such that the result of said superposition equals the flank twist required for the work piece.
