In the previous section, Eq.(4) represents the transfer function of the plunge grinding process. In the common grinding applications, the grinding wheel wear stiffness is several orders of magnitude higher than the cutting stiffness, as it has been shown by Snoeys and Brown .Taking into account this consideration the wear stiffness can be supposed infinite compared with the cutting stiffness ...

The plunge grinding process is either planned a priori or adaptively controlled to achieve a desired surface finish quality using the experimentally calibrated empirical models. This adaptive control system is interfaced to a commercial CNC cylindrical grinding machine tool, and its effectiveness is demonstrated with grinding tests.

This paper studies self-excited vibrations, regenerative and frictional chatters, in a plunge grinding process. In consideration of lateral and torsional workpiece movements, a dynamic model with four degrees of freedom is proposed, which involves state-dependent time delays and Stribeck effect for regenerative and frictional effects, respectively. With this model, by linearising contact angle ...

Grinding vibrations caused by regenerative cutting force and workpiece imbalance are discussed in this study. To regenerate workpiece surface, a grinding wheel is rotated, and pushed towards a rotating workpiece, rubbing and cutting its surface, with regenerative and frictional interactive forces generated. Besides, any mass imbalances of the rotating workpiece or the wheel is another …
