“…The theory of dichromatic speckle correlation has been described by Parry [6], and it is based on the Kirchhoff approximation (KA) [7]. As Fig.2 shows, applying the KA to describe the scattering of a laser beam in TEM 00 mode from a rough surface, ș i indicates the angle of incidence, ș r and ș s indicate the angles of observation.…”

This paper focuses on the influence of curved surface on surface roughness measurement, the method of dichromatic speckle autocorrelation was used in measuring surface roughness, and curvature radius of surface is introduced. The rough surface and the dichromatic speckle patterns are simulated, and the effects of different radius of curved surface on speckle patterns and speckle elongation ratio are discussed. The results show that the factor of surface radius is valid in dichromatic speckle autocorrelation measurement. When the curvature radius is large, the speckle elongation is greater, the deviation of measured surface roughness is smaller. The curvature of rough surface will affect on measurement precision when we measure the roughness by the method of dichromatic speckle autocorrelation.

“…Thus, it is recommended that multiple parameters of the surface roughness of machined surfaces should be studied in order to gain a deep insight intothe implications of machining parameters on surface quality [6]. In some cases, special techniques must beemployed in order to obtain a more accurate estimation of the roughness parameters' values [7], especially online, which is a challenging task [8][9][10].…”

Improvement of the surface quality of machined parts is essential in order to avoid excessive and costly post-processing. Although non-conventional processes can efficiently carry out the machining of difficult-to-cut materials with high productivity, they may also, for various reasons, be related to increased surface roughness. In order to optimize the surface quality of generated surfaces in a reliable way, surface profiles obtained during these processes must be adequately modeled. However, given that most studies have focused on Ra or Rz indicators or are based on the assumption of a normal distribution for the profile heights, relevant models cannot accurately represent the surface characteristics that exist in a real machined surface with a high degree of accuracy. Thus, in the present study, a new modeling approach based on the use of a statistical probability distribution for the surface profile height is proposed. After six different distributions were evaluated on the basis of a three-stage procedure involving different roughness indicators pertaining to the abrasive waterjet (AWJ) milling of pockets, it was found that, although it is not possible to model the nominal values of every roughness parameter simultaneously, in several cases, it is possible to approximate the values of critical indicators such as Ra, Rz, Rsk, Rku and Rp/Rv ratio by Weibull distribution with a sufficient degree of accuracy.
