Influence of Dressing Conditions on Surface Roughness when Surface Grinding SKD11 Steel

Abstract:

This paper presents an optimization of dressing conditions for SKD-11 steel grinding using HaiDuong grinding wheel made in Vietnam. Taguchi method was used to design experiment and calculate the optimized dressing conditions. Effects of the six input parameters including feed rate (S), depth of rough dressing cut (a_edr), rough dressing times (n_r), depth of finish dressing cut (a_edf), finish dressing times (n_f) and non-feeding dressing (n_non) with 4 levels on the machined surface roughness were investigated for optimization process. To find out the influence degree of each input parameter on output results, S/N ratio was analysized. Experimental results show that the average surface roughness after 3 times of the repeated experiments was 0.208 μm and deviation was 11.23% comparing with the predicted values.
