Grinding residual stress optimization under the micro-carburizing effect
The micro-carburizing experiment employs dry grinding, with a maximum grinding depth of up to 250 µm in a single pass and a slowest feeding rate of only 0.01 m/s. This extreme grinding condition is selected to cause full austenitizing and demonstrate the micro-carburizing effect in the grinding contact area.

With the a p decreases, the grinding processes could be conventionally categorized into five forms: (i) Strong grinding defines a p of more than 0.5 mm; (ii) Rough grinding defines a p of 0.1–0.5 mm (Yin et al., 2018). These two processes may result in complex residual stress due to the substantial chipping (Zhang and Shi, 2010).
