Abstract
The invention concerns a method of generating gear teeth, wherein a workpiece which is to receive a toothed profile and a cutting tool are advanced toward each other in a rolling feed motion until each tooth flank of the gear profile has been generated after several passes of the tool, wherein in each pass a cut surface containing at least one flank cut is generated on the workpiece, wherein an auxiliary motion is superimposed on the rolling motion, which has the effect that the flank cuts generated in at least two immediately consecutive passes will be connected to each other. In addition, the invention also concerns a gear-cutting machine with the requisite control features to perform the method.
Claims10
A method of generating gear teeth having tooth flanks (10, 20), wherein a workpiece which is to receive a toothed profile and a cutting tool are advanced toward each other in a rolling feed motion until each tooth flank (10, 20) having the toothed profile has been generated after several passes of the tool, wherein in each pass a cut surface containing at least one flank cut (11, 12, 13, 14) is generated on the workpiece,
- characterized in that
- an auxiliary motion is superimposed on the rolling feed motion whereby flank cuts generated in at least two immediately consecutive passes (11-12, 12-13, 13-14) are connected to each other,
- said method further comprising a last pass of the tool wherein a cut surface is generated by the rolling feed motion without said auxiliary motion.
