MAanufacturing PrAocesses
Primary shaping processes.
casting, forging,
Sand mould casting
Permanent mould casting
Slush casting
Die casting
Centrifugal casting
extruding, rolling, drawing, bending, shearing, spinning,
powder metal forming, squeezing
Machining processes
The common operations used
for this process are turning, planning, shaping, drilling, boring, reaming, sawing, broaching, milling,
grinding, hobbing
Surface finishing processes
polishing, buffing, honing, lapping, abrasive belt grinding, barrel tumbling, electroplating,
superfinishing, sheradizing
Joining processes
welding, riveting, soldering, brazing,
screw fastening, pressing, sintering
Mechanical Working of Metals
Hot Working
Hot rolling
The forming of
bars, plates, sheets, rails, angles, I-beam
and other structural sections are made by
hot rolling
Hot forging
Hot forging, 3. Hot spinning
Hot extrusion
The rods, tubes, structural shapes, flooring strips,and lead covered cables, etc., are the typical products ofextrusion.
Cold bending
Most of the tubing is now-a-days are roll
formed in cold conditions and then welded by resistance welding
cold working
The mechanical working of metal is described as hot working and cold working depending
upon whether the metal is worked above or below the recrystallisation temperature
Processes effecting change in properties
Such processes are heat treatment, hot-working, cold-working and shot peening
