Abstract:
On the basis of thorough studying radial rotation error of the
spindle and differentiation rule of error evaluation , a new method of
minimum regional ring for calculating radial rotation error of the
spindle is discussed. There needs no trial in this method and the best
direction and step of the center trace of minimum regional ring can be
determined immediately. As compared with the conventional methods, it
has the features of high speed and accuracy of the calculation.
Key words: Radial rotation error of spindle
Minimum
regional ring Inclusion
Concentric circle Step
