- Abstract:
- Roundness is an essential geometrical feature in precision engineering metrology especially for quality control of the rotating parts. Talyrond machine becomes one of the main instruments i n roundness measurement . Talyrond HPR TR-73 fitting software data analysis can contribute significantly o n the measurement accuracy. The error characterization of TR-73 software is very important to find an optimum fitting solution in measurement . The final accuracy of a n object is influence by many different parameters.
In this paper, the impact of fitting strategic parameters as computational geometric techniques i n roundness metrology using TR-73 machine have been studied. Strategically geometric ten parameters included two types of fitting filters and four types of software algorithm techniques during four ranges of spectral wave numbers have been estimated experimentally and discussed in details. The experiments have been performed to establish reference data sets of roundness measurements for circular, cylindrical and spherical objects . Measurement results revealed that the accuracy of the maximum roundness have been improved using MZ fitting technique. Moreover, the average of roundness measurement became more accurate by about 65.6% and 57.3% using 2CR and Gaussian strategy respectively, which proved the effectiveness within application range. Thus, establishing references data sets are presented to help the designer and operator to satisfy the best fit for roundness error measurements in nano-scale metrology. - Keywords:
