Abstract
Accuracy and repeatability in measurement is a primary concern in improving and maintaining the quality of a product in an industry. In the case of coordinate measuring machines, these factors are affected due to the ambient conditions. Specifically, change in temperature affects machine geometry and causes positioning errors. As a result, temperature and humidity control inside the housing has become an important and integrated concern of measuring machine. This research concentrates on the modeling, design, control and validation of an air shower to meet a 20 ± 0.1 ¼C specification.
The optimum performance of the control of temperature of air shower is achieved when the proportional valve controlling the flow of cooling water into the radiator is dithered in a sinusoidal pattern. The design modifications enhance the ability to control the temperature inside the air shower, reducing the errors caused by thermal variations
