ELECTROCHEMICAL ENGRAVING OF THIN-WALLED SUS304 WORKPIECE

Abstract

Engraving is a prime importance operation to allow the identification of
nearly all products in everyday life. In this study, the electrochemical engraving
method is used to mark information on thin-walled SUS304 name cards (0.5 -
1mm in thickness). The relationships between the processing parameter inputs
(DC current (I(A)), machining time (t(s)), and electrolytic concentration (C(%))
and criteria output (surface roughness (Ra)) were developed using the Box-
Wilson experimental model to determine the optimal values of the processing
parameters. The results showed that machining time (t(s)) is the most affected
factor, and the optimal technological parameters are (I = 84A, C = 6.775%,
t = 105s). The researched results will be the basis for selecting technological
parameters when engraving similar materials in mass production conditions.
