The paper presents the results of measuring surface roughness and cutting techniques of a water-soluble potassium dihydrogen phosphate (KDP, KH2PO4) crystal. This study is a continuation of the previous research; however, this time, for cutting, a crystal of different nature has been chosen. For research purposes, diamond wire cutting machine RTS 440 has been used. The experiments have been performed changing a single cutting parameter – the vertical feed rate of wire under constant wire speed, tension, cutting method and cutting angle. The obtained results have been presented as the graphs of the dependence of arithmetic average deviation Ra of the surface profile on the feed rate of diamond wire. Also, the dependence of KDP crystal plate cutting time on the feed rate of wire has been established thus obtaining the most optimal feed rate range.
