Paper Abstract

A new method for evaluating position errors and feature countenance parameters of actual measured axis of the Holegroup is proposed and its mathematical models are established in this paper. By means of this method not only can position errors of the Holegroup and any hole position errors be obtained by the least square method and optimization method but also the feature parameters of measured count enance can be obtained. That is straightness and feature countenance parameters of any hole axis in the Hole-group can also be known. By using this method the computer programs which contain the least square method and optimization method are edited. It has been proved that this method conforms with the geometrical tolerance standard. The countenance of error''s curve of measured axis can be expressed very well. The method which is proposed for the first time in this paper is also appliable to the mathematical description of other error curves with different shapes.
