Experiment of Micro-Parts Feeding on Saw-Tooth with the Effect of the Surface Geometry Parameters

Abstract:

In this work, we study experimentally the effect of the geometry parameters of saw-tooth surface and micro-part on the motion of micro-parts. The experiments are performed for a range of saw-tooth pitch, p, micro-part length, l, and exciting frequency applied to the surface, f. By the use of particle tracking velocimetry method, we can achieve time-dependent velocity, and then ensemble-averaged velocity of the micro-parts. The results show that for different l and p but the same relative scale l/p, the profiles of micro-part velocity against the characteristic surface velocity pf are similar. However, they shift along pf axis depending on p. Furthermore, the profiles are the similar for the relative scale l/p of 4 to 100. It seems that the motion of micro-part depends on characteristic surface velocity pf than the relative scale l/p for l/p larger than a certain value.
