The grinding vibration of the blisk-blade belt is related to the process parameters, such as the grinding positive pressure, the belt speed, the feed rate, and the contact wheel hardness. The primary and secondary orders of each influencing factor are grinding positive pressure, belt speed, feed rate, and contact wheel hardness.
Especially in grinding, the dynamic stiffness of a machine influences the process stability enormously. The stability of the grinding process is affected by the specification of the grinding wheel, machine parameters and the condition of the workpiece. Chattering is simply a consequence of vibration within a grinding system.

The objective of this research is to identify how process parameters during the gear grinding process vary and determine if they can predict the noise associated with gears in final assembly. Specifically, this research records the vibrations on the grinding wheel and decomposes them using a Fast Fourier Transform (FFT).
This paper presents the analysis of mechanisms of removal in vibration-assisted grinding process. It is known that generally for machining, application of vibration helps to increase material removal rate, reduces tool wear rate and increases depth of machining. As the failure of a component originates from the surface, effect of
The grinding process is complex with many interrelated parameters, and an initially stable process can become unstable as grinding conditions naturally deteriorate. Forced vibration from machine rotating elements and self-excited vibration produce a relative radial movement between the wheel and workpiece during grinding and the wheel and diamond during …
