the surface grinding process via digital processing of the vibration signals. Experimental tests were performed using a surface tangential grinding machine with a diamond grinding wheel and alumina (Al2O3) test specimens. The vibration signal was measured by an accelerometer and recorded by an oscilloscope at a 2 MHz sampling rate.

How to Reduce the Effect of Vibration in Production Grinding
The vibration amplitude at the second set of conditions was measured at 8 microinches versus 79 microinches when grinding at first set of conditions. Again, the imbalance remained the same. But grinding at conditions consistent with contact-length filtering produced a smooth surface despite the imbalance, without any reduction in productivity.

Measuring vibration on precision grinding machines
Vibration forms. Common forms of vibration on grinding machines tend to fall into two categories – force vibration and self-excited vibration. Force vibration includes wheel imbalances, damaged bearings, bad motors, or grinding wheel imbalances. Force vibration can be present even when the grinding wheel is not in contact with the workpiece.
