Skipping (Rushing through)

Perform a process, or individual stages (e.g. destructible or hazardous operations) at very high speed.
 

EXAMPLE:
  1. The critical operating conditions of a machine: the critical speed or resonant frequency is quickly passed through without damage being caused to the machine.
  2. The cutting of flexible plastic parts is done at very high speeds. The cutting process is finished before the work piece deforms.
  3. A phosphoric acid catalytic converter loses its useful properties at around 350°C, but is active again at temperatures exceeding 700°C. The hazardous region can only be skipped by rapidly heating the catalyst.
  4. The rapid cooling of metal when casting or heat-treating increases its brittleness. If however, the metal is cooled very suddenly, a crystal latticework does not form, but instead, a very strong and useful material called metallic glass results.
