“…7. Waikar and Guo [24] reported that the number of peaks in a unit of sampling area measured for hard turning of AISI 52100 bearing steel with fresh CBN tools and feed of 0.0254 mm/rev is equal to Sds = 3996 pks/ mm^. This difference results from the number of tool traces generated at very small (0.0254/0.01 in.…”

This paper presents the state of surface integrity produced on hardened-high strength 41Cr4 steel after hard machining and finish ball burnishing. Surfaces machined by sequential machining processes were characterized using 2D and 3D surface roughness parameters. Moreover, detailed functionality of the generated surfaces was performed using a set of 3D functional roughness parameters. Among the characteristics of the surface layer, its microstructure, the distribution of microhardness and the residual stresses were determined. This investigation confirms that ball burnishing allows producing surfaces with lower surface roughness and better service properties than those generated by cubic boron nitride (CBN) finish hard turning operations.

The knowledge of contact forces in teeth surfaces during mastication or para-functional movements can help to understand processes related to friction and wear of human dental enamel. The development of a numerical model for analysis of the occlusal contact between two antagonistic teeth is proposed, which includes three basic steps: the characterisation of the surface roughness, its homogenisation using an assumed distribution function and the numerical determination of the resulting forces. Finite element strain results for the main different asperities are statistically combined, deriving the predicted macroscopic behaviour of the interface. Axisymmetric and 3D numerical models with an elasto-plastic constitutive law are used to simulate micro-indentations and micro-contacts, respectively. The contact is allowed to occur locally in planes not necessarily parallel to the surface's mean plane, a problem for which there is no analytical solution. The three identified parameters, homogenised surface hardness (3.68 GPa), surface yield stress (3.08 GPa) and static friction coefficient (0.23), agree with the experimental values reported in the literature.

“…The development of computer-controlled three-dimensional profilemeters in recent decades has allowed the use of this technique to characterize machined surfaces more realistically. Waikar and Guo [14] compared the topography of turned and ground hardened AISI 52100 steel (62 HRC) and reported that, additionally to the regular pattern produced on the surface by the combination of feed rate and tool nose radius when turning (against the random pattern observed after grinding), in general the surface produced by gentle grinding presented loweramplitude parameters (S a , S q , S p , S v , S t , and S z ) compared with turning using fresh and worn inserts and with dry grinding. As far as the functional parameters skewness (S sk ) and kurtosis (S ku ) are concerned, only the surface generated by gentle grinding presented negative S sk , thus indicating superior fluid retention ability, while only abusive grinding produced a surface with S ku higher than three (height distribution with low standard deviation).…”

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). Geometric IrregularitiesOwing to the fact that in most cases hard-part machining is employed as an alternative to grinding, the requirements concerned with surface texture (microgeomet-__________________________________ A.M.
