WebDec 7, 2024 · Rigid tapping is a machining process in which the feed rate is synchronized with the spindle rotation, in order to attain a particular thread pitch. This process eliminates the need for a floating tap holder and provides the ability to tap precise threads even with a solid tap holder. This article provides a comprehensive guide on rigid tapping ... 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.
