Chemical Milling an overview ScienceDirect Topics

Chemical milling process is generally carried out in a series of five steps: cleaning, masking, scribing, etching, and demasking [10]. Fig. 5.1.4 represents the schematic diagram of chemical milling process. At first, the workpiece surface is cleaned properly for removing the contaminants which could negatively impact the quality of the finished part.
