| 摘 要： | 为充分发挥轴承钢GCr15优越的材料性能，保证GCr15轴承等产品的加工质量和加工效率，开展了高速外圆磨削参数优化研究。选用立方氮化硼（CBN）砂轮进行GCr15的高速外圆磨削响应曲面试验，根据试验结果建立磨削力、磨削温度、变质层深度等磨削结果的回归模型。结合回归模型与磨粒的最大未变形切屑厚度模型，综合分析砂轮线速度、工件速度、磨削深度等磨削参数对磨削结果的影响规律。以磨削结果综合最小为目标，进行磨削参数的多目标优化，通过试验验证优化模型和优化结果的正确性。

| Abstract: | The optimization of HSCG parameters was studied for the full using of the superior material performance of bearing steel GCr15, as well as the processing quality and efficiency of bearing products. The response surface experiments of HSCG were carried out on GCr15 with a cubic boron nitride(CBN) grinding wheel. According to the experimental results, the regression models about the grinding results were established for grinding force, grinding temperature and deteriorative layer depth. Combined with the regression models and the maximum undeformed chip thickness model of grains, the influences of grinding parameters, such as grinding wheel speed, workpiece speed and grinding depth, on the grinding results were comprehensively analyzed. For the integrated minimum of grinding results, the multi-objective optimization were carried out on the grinding parameters. The correctness of the optimization models and results were verified by experiments. |
