Abstract
The invention relates to a method for machining a workpiece, preferably of a gear, with a multiple thread worm-shaped cutting tool with several parallel running helical and ridge-shaped cutting edges. To obtain a higher quality of the machining operation the invention proposes the following steps for the method: a) Bringing the cutting tool with the workpiece into mesh by inserting of a first helical cutting edge of the cutting tool in a first gap of the workpiece which has to be machined or has to be produced and machining of the workpiece with the cutting tool in this contact situation; b) Bringing the cutting tool and the workpiece out of mesh; c) Bringing the cutting tool with the workpiece again into mesh by inserting of the first helical cutting edge of the cutting tool in a second gap of the workpiece which is different from the first gap and machining of the workpiece with the cutting tool.
