Summary: | 碩士 === 國立臺灣大學 === 機械工程研究所 === 82 === The purpose of this article is to present a minimum zone method
to estimate the profile error for circular arc and parabola be-
cause the study of the profile error for arc and parabola have
not presented in the past. The minimum zone method proposed in
this article set up the criteria for the minimum zone solution
first,obtained 1-1model from the least-squares method ,utilized
minimum intersectional angle to obtain 2-1 or 1-2model, and
then minimum tangent rotat- ion angle to obtain 2-2model.
Finally, utilized strict rules for data exchange to obtain the
minimum zone solution for circular arc. The minimum zone
solution for parabola was obtained by means of data exchange
and convergent method. Finally, the software which rapidly
displayed the result was developed according to the above
analysis.Comparing with the existing least-squares method
through some examples, it can be shown that the minimum zone
method can provide better result.
