Following on the Report 1,we measured the removed metal per (cm)^2 of cut surfaces and analysed the slag composition, the results thus obtdaicned are as follows, 1) The weight of removed metal ane the width of the kerf increased at increased cutting pressures and showed little difference with increased cutting speed at the same cutting pressure. 2) The slag contained some metallic iron, and the percentage of metallic iron increased with cutting pressure. 3) Irregularity (wauiness and roughness) of the cutting surfaces increased with cutting pressure 4) For plates of thickness 40mm under, we deduced and emprical formula about width of kerf b≦2.0d (b : width of kerf d : nozzle diameter)
