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.

This article discusses the principal process steps, specifications, defects, applications, advantages, and disadvantages of chemical milling (CM) in aerospace industries. The process steps include precleaning, masking, scribing, etching, final cleaning, stripping, and mechanical finishing. The article describes the variables that affect ...

Chemical milling has been an important aerospace process since the late 1950s. Early operations were not environmentally friendly. Chemical milling maskants emitted solvent directly to the atmosphere and large volumes of dissolved aluminum (etchants) required frequent dumping, which also resulted in significant loss of production process time.

Chemical milling is a dynamic process and parts racking is important. In most cases, the parts are racked and submerged in the chem mill solution without any movement or minimal agitation of the solution. But for some intricate parts, it is necessary to have a
