FEED MECHANISM AND WORKING PRINCIPLE OF LATHE
WebSpindle speed settings on the lathe are done in RPMs. To calculate the proper RPM for the tool and the workpiece, we must use the following formula: This simplified version of the RPM formula is the most common formula used in machine shops. This RPM formula can be used for other machining operations as well. http://www.minaprem.com/machining/principle/parameter/what-is-feed-rate-in-machining-its-unit-value-effects-and-selection/ WebJul 27, 2024 · The Feed rate (F in the picture) is the linear speed of the tool as it travels along the part contour. This could be specified in ‘mm per minute’ (mm/min) or ‘mm per revolution’ (mm/rev). On lathes it is always specified in mm/rev, and this makes sense because: 1. The surface finish directly depends on the distance moved per revolution. 2. rochester concrete
