Abstract
A nonlinear mathematical model for spatial straightness error evaluation based on the minimum zone condition is established in this
paper. According to the error analysis, it is proved that the mathematical model for spatial straightness error evaluation cannot be linearized.
A criterion for verification of the existence and uniqueness of the minimum zone solution is proposed. A new computational method is also
proposed, and practical examples are given. Finally, the correctness of this method is demonstrated using a geometrical solution. This new
method is convenient for computation of uniqueness and exactness of the minimum zone solution.
