化学铣切是把零件浸入腐蚀溶液中，对裸露的表面进行腐蚀的加工工艺，主要用于金属。

蚀刻在半导体制造工业中，用于制造集成电路；在航空航天工业中使用，可以在表面铣出凹坑、网格、筋条的薄壁件。

Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. It is mostly used on metals, though other materials are increasingly important. It was developed from armor-decorating and printing etching processes developed during the Renaissance as alternatives to engraving on metal. The process essentially involves bathing the cutting areas in a corrosive chemical known as an etchant, which reacts with the material in the area to be cut and causes the solid material to be dissolved; inert substances known as maskants are used to etch specific areas of the material.
