“…On the other hand, adding a grinding operation increases the total manufacturing cost and time of a component. 27 In addition, there are serious concerns about damages such as surface/subsurface cracks, which are normally accompanied by grinding processes with relatively low fracture toughness and high-hardness materials. 28 Therefore, the modern approach to machining, places elimination, or minimization of the use of the grinding process in the case of such materials is desired.…”

One of the major problems encountered in hardened components such as roller bearings, which work under fatigue loading conditions, is that the requirement of higher surface finishes (≈0.15 µm Ra) cannot be achieved by the sequential hard turning and ball burnishing processes. Such high surface qualities can be generated by additional finishing operations such as grinding. However, despite the improvement in the surface roughness, the grinding process increases both the tensile surface residual stresses and crack initiation sites on the ground surface; therefore, the fatigue behavior of the component may deteriorate. In this study, the effects of adding a grinding operation before the ball burnishing process on the fatigue behavior of AISI 4130 steel were experimentally studied. According to the achieved results, the burnished pre-ground samples show a considerable reduction in the final surface roughness and, at the same time, higher microhardness, higher endurance limit, and smaller area of the fatigue cracking zone. The burnished pre-turned and burnished pre-ground samples showed 4.24% and 10.95% improvements in the endurance limit compared to that of the turned samples, respectively.

“…Grinding is an important process in series of machining operations such as turning, milling, drilling. This process can be used in both rough and finish machining [1][2][3][4][5][6][7][8][9][10][11]. A critical stage that prepares for the grinding wheel after each grinding operation is dressing or sharpening abrasive grains.…”

This study presents the results of a study on multi-objective optimization of internal cylindrical grinding of hardened SKD11 steel in order to find one objective function which satisfy minimum surface roughness, Ra. By this procedure, an optimum set of dressing parameters such as coarse dressing depth, number of coarse dressing, fine dressing depth, number of fine dressing, non-feeding dressing, and dressing feed speed will be found. Taguchi design methodology is accepted to find the optimum set of dressing parameters which can lead a condition of objective function as above mentioned. ANOVA is conducted based on experimental results to find the significance of each input parameter on the responses. The results reveal that the optimum value of surface roughness is 0.111 μm when using the optimum dressing parameters such as fine dressing depth at level of 2, number of fine dressing at level of 3, number of non-feeding dressing at level of 4, number of coarse dressing at level of 3, coarse dressing depth at level of 2, and dressing feed rate at level of 1.

“…Grinding process is an important operation in the machining field where the final shape or finish quality is satisfied for assembling components. It is estimated that 25% of the total expenditures on machining operations are used in industry [1][2][3][4][5][6][7][8]. There have been researches that conduct the optimization process to find the optimum dressing parameters for external grinding, internal grinding, and surface grinding [9][10][11][12][13][14][15].…”

This study has been conducted to optimize the dressing parameters to find the minimum surface roughness for internal grinding of hardened SKD11 steel using the Taguchi method. The input parameters used are coarse dressing depth, number of coarse dressing, fine dressing depth, number of fine dressing, non-feeding dressing, and dressing feed speed. The Analysis of Variance (ANOVA) and an analysis of the signal-to-noise (S/N) response are conducted to estimate the significance of each input parameter on the responses. It shows that the number of coarse dressing has the most decisive impact on Ra (88.28%). Furthermore, the discrepancy of the roughness average from the experiments and that from prediction are minor.
