摘要

摘要: 曲面精密磨抛加工中，由于弹性磨具与曲面接触特征的多样性，弹性磨具呈现不规律的磨损，磨抛效果差且废品率高。为了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，在分析微观磨抛接触特征的基础上建立了残留峰的数学模型，通过数学推导和实验确定了残留峰移除面积与影响磨削精度的主要因素的精确表达式，利用田口法确定各个因素对磨抛效果的影响程度和最佳参数组合，并通过实验验证了该参数组合的正确性。

Abstract: Due to the diversity of contact characteristics between the elastic abrasives and the workpiece surface in the precision grinding operations, the irregular wear appears on the abrasives, followed by poor effects and a high rejection rate. Aiming at the relationship between the processing efficiency and the contact characteristics in theory, a mathematical model for predicting the optimal parameter combination for grinding is conducted based on the Hertz theory. Firstly, taking steel M300 as the study objective,the model for residual peak is established by analyzing the micro contact characteristics of the elastic ball-end abrasives. Secondly, the functional relationship between the residual peak removal area and the main parameters affecting the grinding accuracy is derived. Lastly, the influence degree of the each parameter on the polishing effect and the best parameter combination are gotten with the Taguchi method, and which are verified by a set of experiments.
