Sažetak

Austenitic stainless steel with nickel and molybdenum content (X2 CrNiMo 17-12-2) is frequently used in the food, chemical, or nuclear industries, as well as in medical applications like endourology. Due to the high content of nickel and molybdenum in these steels, their machinability is difficult; however, the surface finishing by lapping of parts made from X2 CrNiMo 17-12-2 steel remains an issue to be addressed. The paper investigates the possibility of obtaining the smallest possible surface roughness based on the selection of an optimum combination of the main parameters that influence machining. The optimization of the machining system could be achieved by changing the setpoints of the four selected input factors (lap disk eccentricity, concentration of the abrasive paste, contact pressure, and duration of machining). Response surface methodology was applied to determine the combination of factor values that ensures the minimum roughness of the machined surface.
