Chemical etching is an important non-traditional
machining process employing chemical etchant to corrode the unwanted section
from thin material for obtaining desired component. In the present study,
chemical etching was performed to etch aluminium alloy (Al7075) which is widely
used in aircraft, automotive and other industries. NaOH was applied at two
different chemical machining temperatures (25 and 50°C) and chemical etchant
concentrations (1 and 2 Mols). The influences of selected chemical etching
parameters on depth of etch and surface roughness were investigated. The
effects of chemical etchant concentration and chemical etching temperature were
positive on depth of etches. Enhancement of chemical etchant concentration increased
depth of etch and the maximum depth of etch was obtained by rising chemical
machining temperature. However, surface roughness was adversely influenced,
high values of chemical etchant concentration and temperature caused poor
surface quality.
