研究了单氧化铝砂轮、白色氧化铝砂轮和立方氮化硼砂轮对超高强度钢Aermet 100进行常规平面磨削时的磨削力和磨削温度。首先，建立了三种砂轮磨削力和磨削温度的数学模型。在此基础上，研究了切屑形成力和摩擦力在磨削力中的作用，并根据数学模型分析了砂轮与工件接触区的热分布。实验结果表明，在相同的磨削工艺参数下，采用CBN砂轮和氧化铝砂轮分别可以获得最小的磨削力和最大的磨削力比。当磨削力大、磨削温度高时，工件材料会局部粘附在单个氧化铝砂轮上。磨削温度处于较高状态主要受砂轮热性能差和冷却液效率低两方面的影响。磨削力和磨削温度的预测值与实验结果进行了比较，结果表明，合理的协议。(C)2014爱思唯尔有限公司版权所有。
This paper investigates grinding force and grinding temperature of ultra-high strength steel Aermet 100 in conventional surface grinding using a single alumina wheel, a white alumina wheel and a cubic boron nitride wheel. First, mathematical models of grinding force and grinding temperature for three wheels were established. Then, the role of chip formation force and friction force in grinding force was investigated and thermal distribution in contact zone between workpiece and wheel was analyzed based on the mathematical model. The experimental result indicated that the minimum grinding force and the maximum grinding force ratio under the same grinding parameters can be achieved when using a CBN wheel and a single alumina wheel, respectively. When the phenomenon of large grinding force and high grinding temperature appeared, the workpiece material would adhere locally to the single alumina wheel. Grinding temperature was in a high state under the effect of two main aspects: poor thermal properties of grinding wheel and low coolant efficiency. The predicted value of grinding force and grinding temperature were compared with those experimentally obtained and the results show a reasonable agreement. (C) 2014 Elsevier B.V. All rights reserved.
