弹性磨具磨抛效率与曲面接触特征关系的研究
Research on Processing Efficiency and Contact Characteristics of Surface Grinding with Elastic Abrasives
摘要
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.关键词
