Calculate the material removal rate and electrode feed rate in the electrochemical machining of an
iron surface that is 25 mm × 25 mm in cross-section, using NaCl in water as electrolyte. The gap
between the tool and the work-piece is 0.25 mm. The supply voltage is 12 volt D.C. The specific
resistance of electrolyte is 3 2 cm. Take for iron:
Valency = 2, Atomic weight = 55.85,Density = 7860 kg/m³.
For the following application, identify one or more nontraditional machining processes that might be used, and present arguments to support your selection. Assume that either the part geometry or the work material (or both) preclude the use of conventional machining. The application is a matrix of 0.1 mm (0.004 in) diameter holes in a plate of 3.2 mm (0.125 in) thick hardened tool steel. The matrix is rectangular, 75 by 125 mm (3.0 by 5.0 in) with the separation between holes in each direction = 1.6 mm ( 0.0625 in).
(b)
During a certain machining experiment at the UCSI workshop, it is observed
that temperature at the tool workpiece interface is 1200 °C at a cutting speed of
300 mm/min with a feed rate of 0.002 mm/rev.
(1)
Analyse how the temperature will be affected if the cutting speed is
increased by 100 %.
(ii)
Detemine the cutting speed necessary to achieve a maximum cutting
temperature of 900 °C.
