The paper presents results of measurements of surface roughnessof clear, colorless sapphire (Al2O3 – corundum modification,aluminum oxide) crystal cut by diamond wire. The diamond wirecutting machine RTS 440 was used for research. Only verticalfeedrate of wire was varied while the wire speed, tension, cuttingmethod and cutting angle were constant. Results are presentedas graphs of dependence of arithmetic average surface profiledeviation Ra on feedrate of the diamond wire. Sapphire plateflatness measurement results are presented as well. Sapphire platecutting time dependence on feedrate of the wire was established.The most optimal feedrate range was obtained.
