Term
Wire EDM (Electrical Discharge Machining)
Definition

A widely used nontraditional machining process that


removes  metal through the repeated sparking of an


electrical current. During machining, the work piece


and an electrode are immersed in a dielectric fluid.

Term
Formula  ->         N=CS*12(in/ft)/(π*d)
Definition
Spindle speed=     cutting speed*12/pie*diameter.
Term
formula-->                 Fm=  ft*nt*N
Definition
Feed rate=feed(in/(tooth*rev)*number of flutes*spindle speed.
Term




formula--->                       Pfr=fm/2

Definition

 

 

Plunge feet rate=feed rate/2
