Abstract

The results of experimental investigation of cutting kerf characteristics of workpieces of electrical steep depending on nozzle pressure p_n of inert gas and cutting speed v_c are presented. It is demonstrated that the kerf width decreases with increase of v_c as v_c^-1/2 and the period of striations on lateral surface decreases with increase of p_n as p_n^-1/2. The obtained relations are in a good agreement with fulfilled estimations.
