22gantry
/ˈɡæntri/A raised framework used to support equipment, signs or a travelling crane above a work area.
Example:
A gantry crane moved the shipping containers into place.
hoist
/hɔɪst/A device used to lift heavy objects using a rope, chain or cable.
Example:
Workers used a hoist to raise the engine out of the car.
metallurgy
/ˈmɛtələrdʒi/The science of the properties and production of metals.
Example:
She studied metallurgy to understand why the alloy cracked.
torsion
/ˈtɔrʃən/A twisting force applied to an object, especially a rod or shaft.
Example:
The shaft failed under repeated torsion.
failsafe
/ˈfeɪlˌseɪf/Designed to default to a safe condition automatically if a part of the system fails.
Example:
The reactor has a failsafe system that shuts it down instantly.
creep
/krip/The slow, permanent deformation of a material under constant stress, especially at high temperature.
Example:
Engineers monitor creep in turbine blades over years of use.
non-conformance
A product or process that fails to meet a required specification or standard.
Example:
The batch was flagged for non-conformance during inspection.
ductility
/dəkˈtɪləti/A material's ability to be stretched or pulled into wire without breaking.
Example:
Copper's high ductility makes it easy to draw into thin wire.
work hardening
When a metal becomes harder and less flexible after being repeatedly bent or shaped.
Example:
Repeated bending caused work hardening in the copper wire before it cracked.
design for manufacture
Designing something so it is easy and cheap to produce.
Example:
Design for manufacture removed nine parts from the assembly.
failure mode and effects analysis
A systematic look at every way something could fail.
Example:
Failure mode and effects analysis found the fault before the tooling was cut.
mean time between failures
The average working life between one breakdown and the next.
Example:
A mean time between failures of nine hundred hours is not good enough.
tribology
The study of friction, wear and lubrication.
Example:
A little tribology would have saved the entire bearing programme.
hysteresis
The lag between a cause and the effect it produces.
Example:
Hysteresis in the sensor made the control loop oscillate.
harmonic
/hɑrˈmɑnɪk/A vibration at a multiple of the main frequency.
Example:
One harmonic shook the whole gantry apart over eleven months.
galvanic corrosion
Corrosion caused by two different metals touching in damp.
Example:
Galvanic corrosion ate the fixings and left the panel untouched.
hydroforming
Shaping metal using high-pressure fluid.
Example:
Hydroforming produced one part where there had been five.
sintering
Forming a solid mass by heating powder without melting it.
Example:
Sintering gives a porosity that machining never could.
jidoka
Stopping a line automatically the moment a fault appears.
Example:
Jidoka stops the line and stopping the line is the point.
poka-yoke
A design that makes a mistake physically impossible.
Example:
One poka-yoke on the jig ended the reversed-part problem for good.
digital twin
A working computer model kept in step with a real machine.
Example:
The digital twin predicted the bearing failure eleven days out.
