Non traditional machining process selection

Process Selection :

The points which should be looked before the selection of these process are as below : 

1. Physical parameters.
2. Properties of the work material and shape to be machined.
3. Process capability or machining characteristics.
4. Economic survey. 

Materials application of the various methods are given in the table below :
  

Process	Aluminium	Steel	Super alloy	Titanium	Refractories	Ceramics	Plastic	Glass
USM	G	F	P	F	G	G	F	G
AJM	F	F	G	F	G	G	F	G
ECM	F	G	G	F	F	N	N	N
CHM	G	G	F	F	P	P	P	F
EDM	F	G	G	G	G	N	N	N
EBM	F	F	F	F	G	G	F	F
LBM	F	F	F	F	P	G	F	F
PAM	G	G	G	F	P	N	P	N

Where

G = Good

F = Fair

P = Poor

N = Not applicable
The processing capability or machining characteristics can be analyzed with respect to :

1. Metal removal rate obtained.
2. Tolerance maintained.
3. The surface finishes obtained.
4. Depth of surface damage.
5. Power requires machining.

The economics of the various process is analyzed by considering :

1. Capital cost.
2. Tooling cost.
3. Consumed power cost.
4. Metal removal rate efficiency.
5. Wear of tooling.
