Question

A carpenter is drilling a hole in a piece of wood with a twist drill running at 600 revolutions per minute. The drill cuts into the wood at a rate of 0.15 mm per revolution.

How fast, in mm per second, does the drill cut into the wood?

Answer 1

0,15mm pro Umdrehung gibt bei 600 Umdrehungen

pro Min dann ja 90mm/ min = 1,5mm/s
