Chemical Machining (CHM):
- Chemical machining is a non-traditional machining process where material is removed from a workpiece through the use of chemical dissolution.
- The process involves the controlled removal of material by immersing the workpiece in a chemical solution known as an etchant.
- The areas of the workpiece that need to be protected from the etchant are masked using a resistant material, leaving only the desired areas exposed for machining.
Steps involved in Chemical Machining:
- Cleaning: The workpiece is cleaned to remove any contaminants that could affect the machining process.
- Masking: The areas that do not need to be machined are covered with a protective maskant.
- Etching: The masked workpiece is immersed in an etchant solution, which chemically dissolves the exposed areas.
- Demasking: The maskant is removed after the desired amount of material has been etched away.
- Finishing: The workpiece is cleaned and finished to remove any residues from the etching process.
Additional Information
Applications of Chemical Machining:
- It is used in the aerospace industry for making intricate parts and components.
- In the electronics industry, it is used for manufacturing circuit boards and microelectronic components.
- It is also employed in the medical field for creating precise surgical instruments and implants.
Advantages of Chemical Machining:
- Can machine complex shapes and fine details.
- Non-contact process, reducing the risk of mechanical stress on the workpiece.
- Suitable for a wide range of materials, including metals and alloys.
