摘要/Abstract

摘要： 为研究微沟槽结构精密磨削形成及其影响规律,以砂轮修整和磨削运动学为基础,建立了微沟槽结构表面的磨削仿真模型。系统分析了修整、磨削参数和节圆长度对微沟槽结构轮廓的影响,阐述了形成完整或干涉微沟槽轮廓的磨削条件,预测了微沟槽轮廓及尺寸,并在碳钢上进行了磨削试验。试验结果与仿真模型的趋势一致,微沟槽结构的轮廓和尺寸受磨削切深和节圆长度的影响变化较大,受修整深度和修整重叠率影响较小;同时经过试验验证,仿真试验所得的微沟槽平均尺寸误差为7.61%,有较高的精度和可靠性。

Abstract: In order to study the influence of micro-groove structure precision grinding, based on grinding wheel dressing and grinding kinematics, a grinding simulation model for the micro-groove structural surface is established. The influence of dressing, grinding parameters and pitch length on the profile of micro-groove structure was analyzed systematically, the grinding conditions for forming complete or interfering micro-groove profile are described, the profile and size of micro-groove are predicted, and the grinding test is carried out on carbon steel. The test results are consistent with the trend of the simulation model. The profile and size of the micro-groove structure are greatly affected by the grinding depth and the pitch length, and the influence on the dressing depth and the dressing overlap rate is small. At the same time, the test is verified by simulation. The simulation result of micro-groove has an average size error of 7.61%, which has high precision and reliability.
