A new breed of micro-machining systems called micro/
meso-scale machine tools (mMTs) are now evolving [1–4]
with the goal of creating micron-scale features with
10_3–10_5 relative accuracies (error divided by feature
size).Among the advantages of mMTs,the motor size
requirement is reduced by the third power of the machine’s
characteristic length resulting in high specific-force and
increased acceleration and jerk capabilities.This is
important since acceleration requirements are one to two
orders of magnitude larger at the micro-scale than the
macro-scale due to unique cutting mechanics and nonlinear
scaling of motion parameters (distances,feed rates
and accelerations).These acceleration requirements can
degrade machine performance due to limiting factors
associated with controller servo update frequency and
closed-loop bandwidth.As the mMT paradigm continues
to evolve,there is a need to formally address performance
evaluation methods for these machines,taking unique
motion parameter considerations into account.
Existing performance evaluation methods for macroscale
machine tools include measurements of geometric
accuracy and surface finish of machined artifacts [5]
(ISO10791-7 [6]),the evaluation of bi-directional positioning
errors [7] (ISO 10791-4),vibration [8] and stiffness.
Given that machined artifact evaluations are impractical
for mMTs due to metrology limitations at the micro-scale,
some mMT researchers have used other evaluation
methods involving feedrates below 3 mm/min [9,10] and
positioning repeatability moves of 300 mm [11],parameters
that fall well outside the proper mMT regime [12] and
result in unrealistic performance evaluations of micromachining
operations.Furthermore,these tests do not
emphasize the large mMT acceleration magnitudes required
to avoid the high forces,excessive tool wear and
poor surface finish encountered at low feedrates due to the
minimum chip thickness effect [13].
Existing performance evaluation methods involve acceleration
capability as a consequence of the test procedure
rather than as the foundation of the test.For example,
