Effect of magnetorheological processing parameters on polishing spots

Based on the theoretical removal function model, the internal relation between the fluid dynamic pressure parameters and the processing parameters of the magnetorheological removal function is analyzed. The main technological parameters affecting the removal function are clarified. The single-factor influence experiment was carried out for four technological parameters (liquid flow, concentration of polishing liquid, immersion depth and thickness of ribbon).The relationship curve between the single factor parameter and the removal function volume and the single factor parameter and the removal area is given. The influence of different single-factor parameters on magnetorheological removal function is obtained. The processing of a concave mirror is guided by this rule. High quality optical elements are obtained.
