The Relationship between Minimum Zone Sphere and Minimum Circumscribed Sphere and Maximum Inscribed Sphere

Abstract: Among the four methods (minimum zone sphere, minimum circumscribed sphere, maximum inscribed sphere, and least square sphere), only the minimum zone sphere complies with ANSI and ISO standards and has the minimum sphericity error value. Evaluation of sphericity error is formulated as a non-differentiable unconstrained optimization problem and hard to handle. The minimum circumscribed sphere and the maximum inscribed sphere are all easily solved by iterative comparisons, so the relationship between the minimum … Show more

“…The core of sphericity evaluation methods (LSS, MIS, MCS and MZS) is to resolve the parameters of the centre of the two concentric sphere surfaces containing all measured points [1][2][3][4][5][6][7][8][9][10][11][12][13]. Upon this, the principle of the GOSA is as follows.…”

“…Experiment shows that the obtained sphericity error is smaller than the least square solution. Meng et al [11][12][13] thought the evaluation of sphericity error is formulated as a non-differentiable unconstrained optimization problem and hard to handle. The minimum circumscribed sphere and the maximum inscribed sphere are all easily solved by iterative comparisons, so the relationship between the minimum zone sphere, the minimum circumscribed sphere and the maximum inscribed sphere is proposed to efficiently solve the minimum zone problem.…”

“…The aforementioned criterion enables the acquisition of a unique minimum sphericity error, and it is also the arbitration method when there is inconsistency in the evaluation of the sphericity error. The minimum zone criterion is an unconstrained and non-differentiable optimization problem, which poses significant challenges in terms of finding a viable solution [11][12][13].…”
