Non-traditional Machining Processes

• Non-traditional machining methods are used to machine harder materials, difficult-to-machine materials and fragile parts more accurately compared to conventional methods of machining.
• Because of absence of physical contact between work and tool, tool wear is minimum in such processes. Also the hardness of the tool does not matter.
• Work material is removed in various ways.
• Chemical machining removes material from the workpiece by the chemical action of an electrolyte. Processes falling under this category include chemical milling, chemical blanking and photochemical blanking.
• Processes such as water jet machining, abrasive water-jet machining, abrasive jet machining and ultrasonic machining use ...
