The subsequent recrystallizations technique, an experimental strain measurement method by use of recrystallization phenomena, has been successfully applied for the observation of machined surface plastic zones with equivalent plastic strain ε≥0.5, 0.12 and 0.02 of type 304 stainless steel. The depth of the zone with ε≥0.5 is very small, 10-50μm, while those with ε≥0.12 and 0.02 are 100-200μm and 200-450μm, respectively. The depths increase with increasing depth of cut and with decreasing rake angle. The relation between the depth of the zones and the cutting parameters is shown. The deformation state ahead of the quick-stop cut was also well visualized by the technique.
