Thickness of material removal in mm
Figure-9: Time required for different material removable thicknesses
The graph shows that time required is directly proportional to the thickness of the material
removed. With direct method of utilisation, the time taken is one half of that of indirect
method of Dynamo-battery-motor method because the overall efficiency of the system is the
product of dynamo efficiency (0.8), battery efficiency(0.8) and motor efficiency(0.8). That
is 08.X0.8X0.8=0.51
5. CONCLUSION
It is concluded that the wind energy can be directly utilized to do surface finishing or any
such mechanical operations like turning, milling and so on. Also, with little automation, we
can make the raw materials to move automatically one after the other in to the equipment
and finished products can be collected at the outlet of the machine. Direct utilisation is more
efficient and less costly compared to indirect method of utilisation.
