Revision with unchanged content. Over the last few years, the specification on the tolerances for various products has become more constricted. Though the machining processes have become more accurate and repeatable, there is a concern about the final step in manufacturing which is measurement. A very small change in temperature can cause significant dimensional changes in the measuring machine, thus causing an error in measurement. This book, therefore, provides the modeling, design, control and validation of an air shower that houses the measuring machine. The problems of the air shower are determined, the corresponding design changes are implemented and different tests are conducted to analyze its performance. This analysis should help shed some light in the field of precision engineering. It should be especially useful to students and professors, or anyone else who may consider studying the air shower system and conduct some experiments.
