A Review of Issues in Photochemical Machining

This paper presents the issues in machining of copper using Photochemical Machining (PCM). Twenty-seven experimental runs base on full factorial (3 3 ) Design of Experiments (DoE) technique can perform. The control parameters can consider the etchant concentration, etching temperature and etching time. The response parameters were Undercut (Uc) and the Surface roughness (Ra). The effects of control parameters on undercut and surface roughness can analyze using Analysis of Variance (ANOVA) technique and their optimal conditions can evaluate. An optimum surface roughness can observe at particular etching temperature, an etching concentration and etchings time. The minimum undercut (Uc) can observe at the particular etching temperature, etching concentration and etching time.
