Casting Forming Plastic Surface manufacturing processes Definition:
Processes Processes Processing processes processes  Powder metallurgy  A measure of the acceptability of the variation of
Sand Forging Injection  Thermal Machining  Contact moulding process
casting Rolling moulding hardening Electrical  Pultrusion
Shell Drawing Reaction  Shot discharge  Stereolithography UTL−LTL
moulding Cold injection peening machining  3D printing C p=
Gravity die forming moulding Electrochemical  Selective laser sintering 6s
casting Cold Compression machining  Laminated object
Pressure heading moulding Electron beam manufacturing  UTL is upper tolerance limit
die casting Swaging Resin machining  Fused filament fabrication  LTL is lower tolerance limit
Centrifugal Superplastic transfer Laser beam  Carburising  s is standard deviation of process variability
casting forming moulding machining  Nitriding  Above equation assumes average to be at midpoint
Investmen Sheet metal Vacuum Chemical  Ion implantation of specification range
t casting shearing forming machining  Anodising
Ceramic Sheet metal Blow Ultrasonic  Chromating One-sided capability:
mould forming moulding machining  Chemical vapour  Used if process average is often offset from
casting Spinning Rotational Abrasive jet deposition specification range
Plaster Metal moulding machining  Physical vapour deposition
mould injection Continuous  Electroless nickel Upper one-sided index:
casting moulding extrusion  Electroplating UTL−X
Squeeze Continuous  Hot dip coating C pu =
casting extrusion  Thermal spraying 3s
 Welding
 Brazing Lower one-sided index:
 Soldering X−LTL
 Thermoplastic welding C pl =
 Adhesive bonding 3s
 Mechanical fastening
techniques  X is process average
 Minimum of Cpu and Cpl used to indicate process
capability, Cpk, known as process capability index.
