Abstract
An algorithm for volumetric calibration is
developed and verified practically by measuring of all geometric
errors after numerical compensation. In this paper, analysis of
the contribution of each of 9 translational and 9 rotational
position dependent errors and each of 3 position independent
errors in total displacement error vector is presented. Changing
only one of the errors, and keeping all the others unchanged, the
final total error is examined using the simulation based on
forward calibration part of the calibration algorithm. The
measurement of all 21 volumetric errors is expensive and time
consuming. Instead of numerical compensation in the controller,
this analysis yields opportunity to enhance accuracy of the
machine, measuring and making correction of only few of the
geometric errors. Results from the simulation showed that
position independent errors have most significant influence on
total displacement error. Decreasing of the squareness error S XY
improves the mean of norms of total displacement vectors about
25%, and percentage of improvement for squareness error S ZX is
about 20%. If all squareness errors are reduced by factor 0.04,
then total improvement is more than 51%.
