The machining time in the lathe work can be calculated for a particular operation if the speed of the job, feed and length of the job is known. If "s" is the feed of the job per revolution expressed in mm per revolution and "l" the length of the job in mm, then a number of revolutions of the job required for a complete cut will be: l/s.
