chemical milling graphite

Manufacturing Processes and Materials: Exercises

a) Chemical machining (CM): This is used for removing a layer of metal material, either shallow or deep, by means of etching using chemical compounds, like acids, bases, etc. This is a comparatively old process and it has several options: 1. chemical milling, 2. chemical blanking and 3. photo-chemical machining.
