Vibrations in gear grinding have not necessarily an integer relation to the rotation of the gear wheel. They might be caused by design parameters of the machine, as e.g. the number of pole pairs of an axle drive [7]. Investigations on non-integer orders of vibrations showed a dependency of the orientation on the manufactured wave fronts; see ...

A grinding machine is a tool or piece of equipment used for removing material from a workpiece via abrasion. They typically employ rotating abrasive wheels to shape, smooth, or finish workpieces through grinding. The machining process uses abrasive particles to remove material from a workpiece's surface.

The results indicate that at grinding speed v s = 25 m/s and grinding depth a p = 60 μm, the damage to the subsurface deformation layer is minimal. The grinding process considerably impacts the stress exerted on the workpiece, with an amplitude ranging from 1.255 × 10 3 to 1.286 × 10 3. Conversely, the strain on the workpiece is …
