Abstract
The paper presents a comparison of single axis simulation results for various
stimuli conditions against measurements for the same stimuli conditions on the
machine. The results compare well and further comparison can be demonstrated
against previously derived lumped parameter models for the same machine.
Sinusoidal and co-sinusoidal inputs are introduced into a complex 2D model
including geometric error components measured directly from the machine by
laser interferometer. The simulated circular position error traces could then be
directly compared with machine measured error traces obtained from using ball
bar plots.
Measured Bode plots based on the swept sine measurement technique show
how the machine is operating across a broad frequency range and pro
