Analyzing and modeling the influence of workpiece thickness on geometry of slot machining wire EDMs
Wire erosion discharge machining is one
of the non-traditional machining processes which use
heat energy of spark to remove material from work piece.
Process parameters have given the major influence
of the
cutting performance on wire EDM. Parameters such as
pulse on time, peak current, wire diameter and discharge
current are well known for their effect surface roughness
and recast layer. The present work aimed to investigate
the influence of: thickness, current and wire speed on the
machining surface. The surface roughness and hardness
have been analyzed assessed. It was conclude that
surface roughness increase with the increase of
thickness and current, and decrease when wire speed
increase. Meanwhile, as work piece thickness increase,
the surface hardness increase but it decreases when
current and wire speed increases
