In this paper are presented the results of a study concerned with the appli
cation of electrocontact-discharge machining in the sawing of metals. Elect
rocontact-discharge sawing (ECDS) was performed with a rotating copper disc
as the tool, with a flow of ordinary water as the work fluid and with a d.
c. source as the power unit. By sawing steel workpieces, ECDS was character
ized technologically from the point of view of the material removal rate, t
he feed velocity, the tool wear, and the workpieces surface integrity. (C)
