硬质合金曲面磨抛过程中，影响因素较多且存在耦合，加工效率低，废品率高。为提高相对滞后的曲面光整技术，从理论上得到磨抛效率与接触特征的关系，以M300钢为研究对象，通过对弹性磨具的微观接触分析，建立残留峰数学模型，得到残留峰移除率与影响磨抛精度的主要因素的精确表达式，确定了各个因素对磨抛效果的影响程度和最佳参数组合，并验证了该参数组合的正确性，为硬质材料曲面超精磨抛提供了理论指导。
Due to the complex influence factors in the processing of cemented carbide surface, followed by low efficiency and a high rejection rate. To improve the technology of finishing the curve surface, and obtain the relationship between processing efficiency and contact characteristics in theory, it takes steel M300 as the study objective and establishes the model of residual peak by analyzing the micro contact characteristics of the elastic abrasives. Through analysis of model, the functional relationship between the residual peak removal area and the main parameters affecting the grinding accuracy is derived. Finally, the influence degree of each parameter on the polishing effect and the best parameter combination is gotten and verified by a set of experiments and provide references to hard precise surface polishing.
