In recent years, the sphericity error calculation has been increasingly favored by technicians. In order to further improve the calculation accuracy and iterative convergence speed of sphericity, the whale optimization algorithm is proposed to solve the sphericity calculation model. First of all, according to the standard, the mathematical model of sphericity is established under the minimum zone method. Secondly, the whale optimization algorithm is introduced. Finally, the algorithm is validated by the instance data. The results show that the algorithm is effective and advantageous in the calculation of sphericity.
