Unconventional machining process finds lot of application in aerospace and precision industries. It is preferred over other conventional methods because of the advent of composite and high strength to weight ratio materials, complex parts and also because of its high accuracy and precision. Usually in unconventional machine tools, trial and error method is used to fix the values of process para...

In this Paper, complete models of three and six phase self commutated synchronous machine drives are presented, considering the effects of both time and space harmonics. First, the equations for calculation of machine inductances are developed. Next, "thyristor-inverter-electric machine" set is modeled in order to derive all the equations for conduction and commutation states. Finally, the resu...

Small holes are drilled in diamond anvil cell gaskets to contain and pressurize samples. As high-pressure technology pushes the multimegabar regime, smaller-tipped diamond anvils are being increasingly utilized. Consequently, well-centered holes with diameters smaller than 100 pm need to be routinely produced in these gaskets made of exceedingly hard metals. We describe the construction of an i...
