Abstract
This thesis presents the integration design of a roundness test machine using a novel
smart stylus probe with a high stiffness air-bearing. The high stiffness air-bearing
minimizes the effect of the spindle runout. The smart stylus design enables active
control on the stylus force. The stylus design is based on the mechatronics concept
and is made of relatively inexpensive parts. The force control is based on the strain
gauge output to control the stylus movement. An optical fiber sensor detects the stylus
position for the roundness measurement. The stylus force control enables active
adjustment of the system response. It is also possible to use a high bandwidth loop for
surface roughness measurement. This realization uses the µ-synthesis procedure to
implement the performance and the uncertainty specifications. The realization allows
the measurement of very small profile change without scratching the test object with
the active stylus. The roundness tester is also built for experimental verification.
