A newly developed measuring probe now allows Liebherr-Verzahntechnik GmbH the possibility of precise corrective measurement in the gear shaping machine. The measuring probe sits directly on the tool spindle and is therefore in the same coordinate system as the pinion type cutter itself. This reduces inaccuracies which might arise due to a tool change or turning a workpiece and leads to considerably higher quality and process reliability.
This paper shows a method to calculate the occurring tooth root stress for involute, external gears with any form of fillets very precisely within a few seconds.
