Abstract:

Effects of diamond abrasive arraying forms on the interdigitated micro-channel were studied according to the design of micro-channel structure. Uniformity of lapping trajectory for fixed lapping was simulated, and fractal dimension of micro-channel was calculated with different abrasive arraying forms, both of macro and micro opening rate of bipolar plate surface were studied. Optimal spiral arraying form of diamond abrasive was obtained by comparing uniformity of lapping trajectory, fractal dimension and opening rate.

Key words: abrasive arraying form, interdigitated micro-channel, uniformity of lapping trajectory, fractal dimension, opening rate
