Development of a method to increase the accuracy of a straightness measurement system for long workpieces

This thesis proposes a new method to extend the measuring range of the Raytec Gepard system for straighness measurements. The system accuracy on long distances without any correction is not compatible with the industrial and operative requests. The idea that is developed in this work is to obtain the straightness measurement of long workpieces as combination of different an shorter steps. Problems and errors related with the application of this method are analyzed and solved.
