measurement capabilities must be understood. The surface metrology was dominated by interferometers and stylus profilometers,
but as technologies have advanced, more comprehensive solutions have been prerequisite. Considering the limitations of contact
systems, the requirements for optical techniques become apparent. In this experimental study, the roughness values from stylus
profilometer were compared with those from the infinite focus and confocal laser scanning type microscopes and 3D optical system
with dual core technology, confocal and interferometry in terms of their own capabilities. Roughness parameter Ra has been
analyzed via SPSS 15.0 (Statistical Package for Social Science) statistically and mathematical model belonging to Ra has been
developed so that Ra = Ra (F, P, C), whereas F expresses feed, P periodicity and C contrast. The statistical results from many tests
indicated that there has been a correlation between the surface roughness and the properties of the surface topography and there have
been slight differences among three different optical instruments on machined metal surfaces as a result of this experimental study
(model significance with 97% correlation factor R2).
