Precision measurements of the Stark shifts in alkali-metal atoms @1,2# have been used to refine the calculations of alkali-metal atomic wave functions, motivated, in part, by precision parity nonconservation measurements in Cs. Hg atoms are used to set one of the most significant limits on a permanent electric dipole moment ~EDM! @3#. The search for an EDM does not require very precise atomic c...

The objective of this paper is to study the effect of the various process parameters i.e. peak current, noload voltage, pulse on time and duty cycle on response parameters by mixing silicon powder in the dielectric fluid of the Electric Discharge Machining (EDM). Response surface methodology (RSM) is used for investigating the effect on these parameters. Central composite design (CCD) is used f...

Among the several non-conventional processes, electrical discharge machining (EDM) is the most widely and successfully applied for the machining of conductive parts. In this technique, the tool has no mechanical contact with the work piece and also the hardness of work piece has no effect on the machining pace. Hence, this technique could be employed to machine hard materials such as super allo...

A sequential process combining laser beam micromachining (LBMM) and micro electro-discharge machining (?EDM) for the micro-drilling purpose was developed to incorporate both methods’ benefits. In this process, a guiding hole is produced through LBMM first, followed by ?EDM applied that same more fine machining. This facilitates stable, efficient regime with faster processing (compared pure ?EDM...
