"To tune or not to tune, that is
Whether 'tis nobler in engineering to suffer
the slings and arrows of erratic machine behavior,
or to take arms against its sea of motion profiles,
And, by tuning, end them."
To adjust (an engine, for example) for maximum
usability or performance. Calibrating something (a musical instrument
or electronic circuit) to a standard frequency.
Tuning a machine is very similar to tuning a musical
instrument such as a guitar. In order for a guitar to produce the music
that it was intended to make, each string must be tuned to the right pitch,
otherwise, the overall sound of the guitar will not sound right. In the
same way, a machine that is not properly tuned is not optimized and is
unable of producing the most efficient motion.
The object of tuning is to tweak the various gains and
motion parameters of a machine so that the resulting motion is optimized
for production purposes. A machine is considered "tuned" if
the its servo perfomance meets its specification requirements.
- Visibly smooth motion.
- Little to no audible noise produced during and after a
- Little to zero position error after the completion of
a commanded motion.
