Force control-based vibration suppression in robotic grinding of large thin-wall shells

Robotics Comput. Integr. Manuf., 2021
Vibration suppression is a major difficulty in the grinding of low-stiffness large thin-wall shells. The paper proposes that effective workpiece vibration control can be performed by a novel force-controlled end-effector integrated into a robotic ...

Problems in Profile Grinding — Angular Plunge Grinding and Surface Grinding

CIRP Annals, 1981
Profiles can be ground using plane and cylindrical grinding techniques, whereby similar problems are encountered in both cases. For example, it is of importance to know whether cylindrical or asymmetrical profiles are to be ground. When grinding asymmetrical profiles axial forces occur, they can constitute a major problem.

It's a grind [grinding technology]

Manufacturing Engineer, 2006
VIPER grinding was developed by Rolls Royce in collaboration with the Grinding Division of Makino-NCMT as a replacement for creep feed grinding of Inconel and other nickel-based alloys using CBN wheels. Using inexpensive vitrified aluminum oxide wheels of small diameter mounted in the spindle of a horizontal machining center (HMC), VIPER grinding has ...
