Validation of a hardware-in-the-loop simulator for investigating and actively damping regenerative chatter in orthogonal cutting

GN Sahu, S Vashisht, P Wahi, M Law - CIRP Journal of Manufacturing …, 2020 - Elsevier
Abstract Machine tool productivity and part surface quality are fundamentally limited by
chatter occurring due to regenerative type self-excited vibrations. Efficacy of the existing high …

Emulating bistabilities in turning to devise gain tuning strategies to actively damp them using a hardware-in-the-loop simulator

GN Sahu, P Jain, P Wahi, M Law - CIRP Journal of Manufacturing Science …, 2021 - Elsevier
Bistabilities in turning are characterized by the process being stable for small perturbations
and unstable for larger ones. These bistabilities occur due to nonlinearities in cutting force …
