Abstract

The process of chemical machining consists of the removal of material from specific areas, through corrosion of the substrate by a strong chemical reaction through a reagent substance, under controlled conditions. It is one of the most important non-conventional machining processes, with which it is possible to perform complex geometries with reduced dimensions or to reduce the weight of certain parts. Therefore, the objective of this work is the evaluation of the process of chemical machining with NaOH in square aluminum tube through the variation of its parameters. For this, the aluminum was machined with the variation of the following parameters: reagent concentration, reaction temperature and reaction time. The characterization of the specimens was performed by optical microscopy and analysis of the removal rate from which one can observe the best conditions to perform the chemical machining process.
