Influence of grinding conditions on the topographic characteristic of machined surfaces

This paper compares the ability of grinding processes to enhance functional properties of the surface textures produced. The main objective of such a comparison is to facilitate the decision about precision grinding operations. The experimental study performed includes two grinding operations using electro-corundum Al2O3 and CBN wheels. For this purpose, the topographic features of ground surfaces with the Sa roughness parameter of about 0.2?m were compared. Apart from the set of 3D roughness parameters, the frequency, fractal, wavelet and motif characteristics were analyzed.
