This paper investigates the effect of input shaping parameters on driving characteristics of XY stage. When applying real time input shaping schemes to actual XY stages, time spacing and acceleration time are critical parameters to be determined. In order to evaluate these parameters on driving characteristics of XY stage, this paper implements input shaping algorithms with the time spacing and acceleration time. The results show that driving characteristics of XY stage can be significantly influenced by time spacing and acceleration time.

This paper presents a result of comparison between touch trigger probe and atomic force probe for coordinate measuring machines (CMMs). Typical CMMs (touch trigger probe based CMMs) often lead to some errors associated with object curvature and difference in triggering sensitivity. Their applicability is limited only to hard objects. The aim of this work is to develop a trigger sensor for CMMs using atomic force. In order to show the applicability of atomic force as a trigger sensor, a cylindrical shape is measured with a CMM and an atomic force microscope. Three different touch probe heads with different ball sizes are tested. The experiments show that smaller ball provides better results for curved objects. The experimental results also show that the performance of atomic force as a trigger sensor is about that of the smallest ball probe. In addition, experiments are also performed to measure soft objects. Finally, this paper suggests a trigger sensor using atomic force for CMMs.
