Feed rate in slab milling operation is equal to

1. rotation per minute (rpm)
2. product of rpm and number of teeth in the cutter
3. product of rpm, feed per tooth and number of teeth in the cutter
4. product of rpm, feed per tooth and number of teeth in contact

Correct answer: product of rpm, feed per tooth and number of teeth in the cutter

Solution

The feed rate in slab milling is determined by multiplying the rotation speed (rpm) by the feed per tooth and the number of teeth on the cutter, as this accounts for the total distance the cutter moves through the material per minute.
