Abstract
Creep-Feed Grinding (CFG) is one of the none-traditional machining in which form grinding to full depth is performed in limited number of passes. During this study, samples were ground with variable depth of cut and dressing conditions while the other parameters were constant. Continuous Dressing (CD) and Non Continuous Dressing (NCD) with the different number of passes were applied. After machining, surface integrity was studied and in order to investigate the surface micro-cracks, Chemical Etch + FPI and Thermal shock + FPI were performed. For determining micro-structural changes in ground specimens as a criteria in measuring the level of residual stress, a set of recrystallization processes were carried out on them and average grain size were measured. The results show, however, changing in depth of cut hasn’t influenced on micro-cracks, quality of surface roughness has descended in terms of increasing the depth of cut.
