Summary: Magnetorheological finishing (MRF) has become the mainstream method for ultra-precision manufacturing of optics due to its high certainty and low damage. However, there are still gaps in the research on the characteristics of the tool influence function for the MRF method, which results in a lack of effective theoretical support for parameter optimization and quality improvement. This paper demonstrates the mapping relationship between various process parameters and the evaluation indexes of the influence function based on orthogonal tests. A characteristic length coefficient is proposed to suppress ripple errors. The experiment results show that selecting reasonable characteristic length coefficient and line spacing can significantly improve the final quality of the components.
