- Abstract:
- The demand on the precision of machine tools is steadily increasing. In this context, the intrinsic accuracy of the machine tools is no longer sufficient. Nowadays volumetric compensation is applied to minimize the errors of the tool center point.
This paper presents a new, flexible, high precision coordinate measurement system which also offers a great automation potential. Its principle is based on white-light interferometry. The system measures the distance between an emitter and minimum three reflectors. The position of the emitter with respect to the reflectors is determined via multilateration. Therefore, environmental conditions need to be measured and effects like thermal expansion needto be compensated by software. The mathematical and physical models for this compensation have been developed and applied to the system.
Measurements were done under workshop conditions and the results show that the precision of µ-GPS sy stem is comparable to nowadays measurement systems which are used for machine calibrations. Additionally the µ-G PS system allows a high precision 3-dimensional determination of the position. The calibration process can be done fully automated which is completely new in this kind of applications. - Keywords:
