What does chemical milling do?

Answer 1

Chemical milling is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape or dimensions. It is most commonly used on metals however other materials are becoming increasingly important. It was developed armor-decorating and printing etching processes developed during the Renaissance as alternatives to engraving on metal.

Answer 2

Chemical milling is a process used to remove material from a workpiece by immersing it in a chemical solution that selectively erodes the unwanted material. This process is often used to achieve complex shapes or fine details that would be difficult or impossible to achieve using traditional machining methods.
