杨木磨削力的影响因素及最佳磨削参数研究

为研究杨木磨削力的影响因素和最佳磨削参数,通过正交试验设计,研究砂带磨削杨木时磨料粒度、进给速度、磨削速度、磨削厚度对磨削力和法向力的影响,采用直观分析和方差分析研究了影响磨削力和法向力的主要因素,并采用模糊数学综合评判方法对磨削力和磨削质量进行综合评判和优化选择。结果表明:磨削厚度对磨削力和法向力的影响最大,其次为进给速度,磨料粒度和磨削速度对磨削力和法向力的影响较小;杨木的最佳磨削工艺参数为磨料粒度60目、进给速度2.5 m/min、磨削速度10.74 m/s、磨削厚度0.1 mm。

Profit Optimization of External Cylindrical Grinding

This article presents a study on profit optimization of external cylindrical grinding. In the optimization problem, the influences of several grinding process parameters such as the initial grinding wheel diameter, the wheel life, the total dressing depth as well as the effect of many cost components were investigated. A model for determination of optimum exchanged grinding wheel diameter was proposed. With this optimum diameter, a new and effective way of using the grinding wheel was proposed.
