Effects of Grinding Conditions on Fatigue Behaviour of 42 CD 4 Grade Steel

The Development of a Mathematical Model for Predicting the Depth of Plastic Deformation in a Machined Surface

“…Such properties include dimensional stability, fatigue strength, corrosion resistance, wear resistance, warpage of a machined part, static and dynamic strength, and magnetization (18,22,23,24,25,26,27). Components with thin cross sections can undergo some deflection after machining due to the resultant residual stresses, and thus lose dimensional accuracy.…”

“…Reviewing previous work on the mechanics of metal cutting and residual stresses in machining indicates that there are numerous papers dealing with the existence of plastic deformation in a machined surface (8,9,11,26), and correlations between the level of residual stress and machining parameters (18,23,25,27). Despite the amount of research in this area, there exists no analytical model to predict the depth of damage in the machined surface.…”

Development of a surface engineering strategy to quantify the sensitivity of surface integrity features in fatigue performance

“…Some authors have proposed to tailor surface integrity by modifying manufacturing conditions. For example, Skalli 16 investigated various grinding conditions to explore the sensitivity of the fatigue resistance of AISI4140 steel to residual stress and surface roughness. Moussaoui et al 17 made a similar investigation by varying milling conditions of a TA6V alloy to obtain various surface roughness values and residual stress states in the external layer.…”
