3.2 Effect of grinding depth. The four flanks A 1, A 2, B 1, and B 2 are each generated by one wheel in the machining process and the grinding depth therein is varied to provide a certain angle between the flank and workpiece end-surface. In the micro-drill bit, the grinding depth is minimal and near-zero (at least in theoretical terms).
