Abstract
In a first step for the purpose of precentering, the dressing too; (,), without axial movement, is brought into contact with the circumference of the rotating grinding worm (,), and those rotary-angle positions of the grinding worm (,) at which the overrunning of the thread gap (,) starts of ends are determined by means of an acoustic-sensor signal and the shaft-angle encoder (,) of the grinding spindle (,). In a second step for the purpose of precision centering, the dressing tool (,) fed into the thread gap (,) is brought into contact with the left-hand and right-hand tooth flanks (,) by axial displacement. In this case, the axial infeed is stopped by means of the acoustic-sensor signal, and the exact grinding-worm thread center is calculated from the contact positions of the dressing tool (,) achieved.
