This second part out of 3 presentations regarding the review "Non Traditional Machining Processes" is an explanation ofNTM Processes classified as chemical, electrochemical and mechanical processes. Besides explaining the functioning of the used production equipment, it highlights the differences between those processes and the fields of application of each one.

The full review is composed of 4 presentations as follows:  1- Conventional machining vs Non Traditional machining (1st video presentation)  2- Chemical and Electrochemical Processes (2nd video presentation)  3- Mechanical Processes (2nd video presentation)  4- Thermal Processes (3rd video presentation)

The 2nd video presentation, which is the current one, is organized as follows:

2- Chemical and Electrochemical Processes (How chemical machining works?  - Photochemical machining  - How electrochemical machining works? - Differences between CHM and ECM) 3- Mechanical Processes (Abrasive flow machining - Waterjet machining - Abrasive waterjet machining - WJM vs AWJM - Abrasive jet machining - AJM vs sandblasting - Ultrasonic machining - Abrasive jet vs ultrasonic machining )
