Outside diameter OD and face grooving operations are shown in Figures and respectively. Internal threading or tapping will be discussed in a later chapter. Grooving or Recessing Operations Grooving or recessing operations sometimes also called necking operations are often done on workpiece shoulders to ensure the correct fit for mating parts Fig. When a thread is required to run the full length of the part to a shoulder a groove is usually machined to allow full travel of the nut. Fig. Grooving the workpiece prior to cylindrical grinding operations allows the grinding wheel to completely grind the workpiece without touching the shoulder.
