The surface roughness chart is a concept that expresses the amount and extent of deviation of a surface from being perfectly flat. As it is practically impossible to manufacture a completely flat surface on the microscopic level, every surface has a certain value of roughness that can be measured with the use of a profilometer.Depending on the scale of the deviations …

Surface integrity was assessed in terms of surface roughness (Ra and Rz), observations of SEM images and microhardness. The results showed that Inconel 625 is highly susceptible to work hardening during grinding. The grinding wheel speed (v s) was the parameter of greatest effect and the best results were obtained when v s =15 m/s.

When grinding with conventional abrasive grinding wheels, such as Al 2 O 3 and SiC, which have poor heat thermal conductivity, approximately 60–85% of the generated heat during grinding is directed to the workpiece and, as a consequence, thermal damages on both surface and sub-surface of the material may occur.

Thus, for larger hard specimens higher grinding/polishing pressures increase stock removal rates, however higher pressure also increases the amount of surface and subsurface damage. Note for SiC grinding papers, as the abrasive grains dull and cut rates decrease, increasing grinding pressures can extend the life of the SiC paper.
