OPTIMIZATION OF THE SUPERFINISHING PROCESS

By superfinishing process, ultra precision machining process of cylindrical, conical, spherical and even flat surface machine parts is performed. These parts must have high wear resistance and low coefficient of friction. In this paper impact factors on surface roughness are determined. According to the factors test plan and regression analysis, extend equation for mean arithmetical roughness is given. In other to get minimum values of the surface roughness, optimization of the mathematical model is done and optimal values of the examined factors are determined. The obtained results are, according to the experiment plan, valid for the testing of material 34 CrNiMo6. The test results are to be probably applied to other materials, however, has to be proved for each separate case.
