Quizplus · Accepted Answer

The correct indexing movement for cutting 14 teeth is 2 complete turns and 18 holes in a 21-hole circle. This is because the indexing movement is calculated using the formula: (40/N) * number of holes in the circle, where N is the number of teeth. For 14 teeth, (40/14) = 2 complete turns and 18/21 of a turn.
