STUDY ON INFLUENCE OF THE IGNITION VOLTAGES (Uz) AND THE ELECTRIC SPARK INTENSITY (Ie) TO THE SURFACE ROUGHNESS WHEN SUS44C STEEL PROCESSING ON THE CHMER CW-420HS WIRE ELECTRICAL DISCHARGE MACHINING

Abstract

The paper presents results of research on influence of the ignition voltages (U_z) and the electric spark intensity (I_e) to the surface roughness use wire cutting method by copper wire for the SUS440C steel material on CHMER CW-420HS wire cutting machine. The result of this study is the basis for the technologists to select the appropriate cutting mode when wire cutting by copper wire on CHMER CW-420HS for SUS440C steel material.
