The area influenced by any given hole is found as follows: (1) Divide angle at hole by 180°. (2) Multiply total area of entire prism by above result. (3) Multiply area found by (2) by the average thickness (found by solution of the formula) of ore in the hole, which thus transforms this smaller prism into volume.

Feed rate = RPM x chip load x number of teeth. This formula gives you feed rate in IPM or mm/min based on whether you used the metric or imperial table. If you prefer to use cutting feed (IPR) instead of feed rate, you should remember not to multiply by RPM. So, cutting feed = chip load x number of teeth.
