Mechanical Definitions |
Fabrication : The making of machines, structures, or
process equipment for the chemical or fertilizer sector, by
cutting, shaping and assembling components made from raw materials.
In other way the manufacture of structural or electromechanical
parts. |
Face Milling : It is a process of milling flat surfaces
perpendicular to the rotational axis of the cutting tool. |
Failure Rate : It is the probability of failure per unit
of time of items in operation. It can be estimated as a ratio
of the number of failures to the accumulated operating time
for the items. It is usually time dependent. |
Fall block : It is a pulley block which rises and falls
with the load on a lifting tackle. |
Faller : It is a machine part whose operation depends
on a falling action. |
Fan : It is a device which consists of a rotating paddle
wheel or an airscrew with or without casting for producing currents
in order to circulate, exhaust, or deliver large volumes of
air or gas. There is a vane to keep the sails of a windmill
facing the direction of the wind. |
Fan Rating : The head, quantity, power and efficiency
expected from a fan operating at peak efficiency. |
Fan Static Pressure : The total pressure rise diminished
by the velocity pressure in the fan outlet. |
Fan Test : It is a process of observing quantity, total
pressure and power of air calculated by a fan running at a known
constant speed. |
Faucet : It is a fixture through which water is drawn
from a pipe or vessel. |
Feathering : It is a pitch position in a controllable-pitch
propeller, used in the event of engine failure to stop the windmilling
action, and occurs when the blade angel is about 90o
to the plane of rotation. It is also called as Full Feathering.
|
Feed : It is a forward motion which is imparted to the
cutters or drills of cutting or drilling machinery. |
