Abstract

Abstract: Micro-parts and devices are manufactured by various processes like electrochemical discharge micro-machining process (µ-ECDM) for utilizing in modern industry. In this paper an automated spring feed µ-ECDM set up with template guided CAM follower mechanism in tool holding unit has been applied for improving micro-machining performances. This paper focuses mainly on the parametric effects of applied voltage (V), pulse frequency (f), duty ratio (%) and electrolyte concentration (wt%) on different machining performances characteristics such as material removal rate, overcut, heat affected zone, surface roughness and machining depth. The paper also includes the analysis on surface roughness integrity of micro-channel cutting on silica glass (SiO2 + NaSiO3 ) by µ-ECDM process. Application of micro-channels has been reported for utilization as lab on chips or as micro-fluidic channel and achieved better micro-machining performances using spring feed mechanism at the parametric combination of 50 V/10wt%/200 Hz/45% duty ratio/40 mm inter electrode gap (IEG) by µ-ECDM process during micro-channel cutting.
