Regarding the effect of vibration frequency on the removal rate, for a given
amplitude, the increase in vibration frequency reduces the removal rate
(Figure 10.8). This trend may be related to the small chipping time allowed
for each grain such that lower chipping action prevails causing a decrease in
removal rate. The same gure shows that, for a given frequency, the increase
of removal rate at higher amplitudes.
Abrasive grains: The removal rate rises at greater abrasive grain sizes
until that size reaches the vibration amplitude, at which stage the material
removal rate decreases (Figure 10.9). When the grain si ...
