Quick Summary

Chemical machining (CHM) is a non-conventional machining process that removes metal through controlled chemical reactions. Unlike traditional machining, it doesn't rely on a tool harder than the workpiece. Instead, CHM uses chemical solutions to etch away material from selected or overall areas. This method is related to the process used for creating printing and engraving plates.1

Two types of CHM processes exist:
* Chemical blanking: Used for cutting thin metal parts.1
* Chemical milling: Used for removing metal from specific or entire sections of metal parts.1

Photochemical machining (PCM) is an extension of CHM that utilizes photographic and chemical etching techniques to produce components, particularly from metals like stainless steel.2
