Firstly, the allowable intergroup difference is determined by the relationship of polishing indentation and removal depth. Secondly, the distribution of grouping points is determined by the profile difference of sampled blades. Thirdly, the profile consistency of two blades is expressed as the vector difference of measurement data for grouping points, and the grouping result can be established with the Ray-Turi index and allowable intergroup difference. Finally, the grouping and polishing experiment for batch blades has been performed to demonstrate the effectiveness of the proposed method, and the results show that it can improve the profile consistency within each group (less than 5 mm for the experiment). The area exceeding the allowable intergroup difference between groups is more than %. After multi-spindle array polishing, the cross-sectional profile of intergroup blades is less than mm, and the precision difference at the same position is less than mm, which shows that the proposed method is helpful to realize high-quality multi-spindle synchronous polishing
