1. Explain the working principle of a milling machine?
Rely on the tool rotation , moving or rotating the workpiece on the machine bench , to achieve the purpose of processing
It's not as simple as that. Working volume on a milling machine depends on how many axes it has. 3-axis milling machine is pretty simple(X*Y*Z), but 4-axis and 5-axis working volume are not easy to calculate.
Explain the workin principle of uln and its abbreviation
The workpiece is holding on the worktable of the machine. The table movement controls the feed of workpiece against the rotating cutter. The cutter is mounted on a spindle or arbor and revolves at high speed. Except for rotation the cutter has no other motion. As the workpiece advances, the cutter teeth remove the metal from the surface of workpiece and the desired shape is produced. reference- http://engineering.myindialist.com/2009/principle-and-working-of-milling-machine/

A dc generator is a machine which works on the principle of electro magnetic induction $it converts the mechanical energy into electrical energy.
A "horizontal maching center" has a horizontal spindle. With a horizontal spindle, tools stick out the side of the tool holder and cut across the side of a part (workpiece). Horizontal machining centers are far more expensive than equivalent capacity vertical machines, but have several advantages. Usually the tool holder of a horizontal machine is more ridgid. Also,when machining the side of a part, metal chips fall out of the area being cut, leaving an uncluttered cutting area.A "vertical machining center" has a vertical spindle. With a vertical spindle, tools stick straight down from the tool holder, and often cut across the top of a part. One disadvantage of vertical machining is that when tools cut across the top of a part, the metal shavings, called "chips," often pile up around the tool and interfere with the cutting action. However, vertical machining centers are more common, primarily because they are less expensive than equivalent capacity horizontal machines.
The working principle of a turbo generator is that of forcing extremely hot condensed air into the piston chamber. The hot condensed air reduces the need for fuel.
