Why should chips be broken up?

Bad chip breaking also affects productivity. Long chips take up more room in the hopper, which requires it to be emptied more often, but it's not as full in terms of the weight of chips. When combined with the time lost due to stopping the machine and removing chips, productivity is reduced and per-part costs are higher.
