   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

   Common activity bases used in the calculation include direct labor costs, direct labor hours, or machine hours. This is related to an activity rate which is a similar calculation used in Activity-based costing. A pre-determined overhead rate is normally the term when using a single, plant-wide base to calculate and apply overhead.

   Machine shop calculations, to convert blueprint dimensions and perform calculations based on material dimensions and properties. These nomograms often included markings for standard dimensions and for available manufactured parts.

5. Surface feet per minute - Wikipedia

   en.wikipedia.org/wiki/Surface_feet_per_minute

   SFM is a combination of diameter and the velocity of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 surface meter per second (meter per second, or m/s, is the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM.

6. Overall equipment effectiveness - Wikipedia

   The Standard Rate for the part being produced is 40 Units/Hour or 1.5 Minutes/Unit The Work Center produces 242 Total Units during the shift. Note: The basis is Total Units, not Good Units. The Performance metric does not penalize for Quality. Time to Produce Parts = 242 Units * 1.5 Minutes/Unit = 363 Minutes
