“…Similar results were reported by [27], who observed that both turning with PCBN tools and grinding with Al 2 O 3 wheels induced compressive residual stresses on hardened AISI 52100 steel (60-62 HRC). However, while the peak stress took place at the surface for the ground specimens and decreased steeply, in the case of the turned samples the maximum value was recorded at a depth of 10-20 µm and decreased smoothly.…”

“…A direct relationship between the presence of the white layer on the machined subsurface and both edge preparation and depth of cut was reported by [27], who noticed that when turning AISI 52100 bearing hardened to 60-62 HRC with PCBN inserts, the combination of large edge hone radius (r h = 70 μm) and high depth of cut (a p = 0.255 mm) results in the formation of an untempered martensite layer followed by an overtempered martensite layer, not present either after turning with tools possessing low edge radius (r h = 25 μm) at low depth of cut (a p = 0.051 mm), or after grinding and superfinishing.…”

“…The fatigue behaviour of hardened AISI 52100 steel (60-62 HRC) specimens subjected to turning with PCBN and grinding with Al 2 O 3 was assessed by [27]. Tension-tension axial tests were performed and the results indicated that the fatigue life of the hard-turned specimens outperformed those produced by grinding.…”

Surface integrity comprises the study of the alterations induced during the manufacture of a component that might affect its properties and service performance. Therefore, additionally to geometric irregularities (surface texture and both dimensional and geometric deviations), the study on surface alterations (such as metallurgical alterations, cracks and residual stresses) induced by hard-part machining is of utmost importance, especially in the case of components subjected to dynamic loading. Consequently, this chapter is focused on the investigation of the influence of tool material and geometry and cutting parameters on the surface integrity of components subjected to hard-part machining and, when applicable, comparisons are drawn with grinding and non-conventional processes, especially electrical discharge machining (EDM).

The present article focuses on the influence of machining on the fatigue life of a titanium alloy: Ti6Al4V. An experimental design was adopted in order to highlight the effects of machining parameters on surface integrity while generating very different surfaces with a view to subsequent fatigue testing (four point bending tests). Firstly, the impact of machining parameters on surface integrity was demonstrated. Then, the influence of surface integrity on fatigue lifetime was observed: no influence of the geometric and metallurgical parameters was observed. However, the mechanical parameter (e.g., residual stress) seemed to have a preponderant influence. To conclude, a machining plan of procedure was proposed to significantly improve the fatigue lifetime as compared with a reference industrial plan of procedure.

This alternative represents a significant material removal rates and keeps an improved surface finish with a better fatigue performance [1]. Hard turning requires the use of inserts that offer a high wear resistance and a chemical stability at high temperature.…”

The increasing industrial demand for hard materials and their wide range of applications requires significant investigations to improve their machinability. Therefore, the current study addresses cutting forces and surface roughness during hard turning of AISI 52100 steel (59 hardness Rockwell C (HRC)) using ceramic tool. Turning experiments were held out by varying cutting speed, depth of cut, feed rate, and tool nose radius. For so doing, a central composite design (CCD) was adopted including 30 tests. Cutting forces and surface roughness were modeled using response surface methodology (RSM). The effects of each input parameter on output responses were investigated using analysis of variance (ANOVA) and response surface graphics. The findings of this study demonstrated that the force components were significantly influenced by depth of cut, followed by feed rate with a lower degree. Likewise, the negative result of the small undeformed chip thickness on surface roughness was reduced by the employment of large nose radius. Conclusively, a correlation between cutting force behavior and surface roughness was established and confirmed by the threedimensional topographic maps of the machined surfaces. The RSM was utilized to define the optimal machining parameters.
