Non-Conventional
An unconventional machining process
(or non-traditional machining process) is
a special type of machining process in
which there is no direct contact between
the tool and the work piece.
In unconventional machining, a form of
energy is used to remove unwanted
material from a given work piece

Electrochemical Machining
Processes: ECM removes material at the anode
(work piece) using current controlled
electrochemical process. By feeding a
shaped cathode (tool or electrode)
towards the work piece, the reverse
shape of the tool is copied to the work
piece.
Electrochemical Machining
Processes:1. Electrochemical machining (ECM)
2. Electrochemical debarring (ECD)
3. Electrochemical grinding (ECG)
Electrochemical machining (ECM
Electrochemical debarring (ECD)
In Electrochemical Deburring (ECD),
burrs are dissolved from metallic
workpieces electrochemically and are
flushed away by pressurized electrolyte.
Electrochemical grinding (ECG)
ECG that combines electrolytic activity
with the physical removal of material by
means of charged grinding wheels.
Advantages
No mechanical force
There is no cutting forces therefore
clamping is not required except for
controlled motion of the work piece.
There is no heat affected zone.
Very accurate.
Relatively fast
Economics
The process is economical when a
large number of complex identical
products need to be made
Several tools could be connected to a
cassette to make many cavities
simultaneously.
Thanks for your attention.
