width gas journal bearings with three axial grooves are analyzed by bifurcation diagram, orbit
diagram, Poincare´ map diagram and frequency diagram. The numerical results reveal periodic,
period-doubling, period-4, period-8 and chaotic motion of nonlinear behaviors of the system.

Abstract: In the application of a miniature serial-link coordinate measuring machine, it is
necessary to calibrate the structural parameters and improve the positioning accuracy for
accurate task performance. In this study, using a designed compound calibration artefact, a new
calibration method which includes kinematic calibration and laser tool centre point (TCP)
calibration is proposed. In the kinematic calibration, geometric parameters included in the
kinematic model can be identified by using the constraint that the cone angle or cylinder
diameter for several different positions is invariable. For the laser TCP calibration, the relative
