硬脆材料端面微磨削的磨削力及试验研究

摘要

端面微磨削对于加工硬脆材料具有显著的优势.磨削力是磨削机理研究的主要参数之一.本文基于微磨削的特点和逆磨与顺磨的不同,建立了磨削力模型.采用石英玻璃对端面微磨削进行实验研究.通过实验数据对理论模型参数值进行确定,完善并修正磨削力模型.通过实验测得的数据验证磨削力理论模型的正确性,并分析误差产生的原因.%Micro end grinding has significant advantages for processing hard and brittle materials.Grinding forces are important characteristic parameters of micro grinding mechanism research.A theoretical model of the grinding force is built which considers micro grinding characteristics and the differences between up grinding and down grinding.The silica glass is used for grinding experiment research.Through the experiment data, parameter values of the theoretical model can be determined, and the grinding force model can be perfected.The experimental data verifies the theoretical model of grinding force and the error is analyzed.
