【 摘 要 】

Chemical machining is oldest of non-traditional machining processes employed as micromachining process to produce micron-size components. The technique is broadly applied to machine geometrically complex parts of thin and flat materials. Etchants (namely Fe Cl3 + HNO3) affected by it is initial concentration, machining time and machining temperature on the surface finish of stainless steel 304. Three machining variables temperatures (40, 45 and 50 °C) for every one of which three machining times (4, 7, and 10 min) were utilized as machining parameters. Rate of Metal removal was determined based on weight loss due to corrosion. Design of experimental by Taguchi, L 9 (3×3) mixed orthogonal array is used to determine the material removal rate, surface roughness, analysis of variance, and to optimize the process parameters. R Square pieces was predicted by the analysis of independent values to portend the dependent values, and were 100% and 93% for mean material removal rate and surface roughness, individually.
