为降低ＤＺ４定向凝固镍基高温合金的磨削温度，防止磨削烧伤，本文在通过实验方法建立 ＤＺ４合金磨削加工时磨削比能与弧区热流密度计算公式的基础上，利用基于遗传算法的多目标约束优化方法，对磨削 ＤＺ４合金时的砂轮形貌与磨削工艺参数进行了优化设计，为这些参数的合理选择提供了理论依据。
In order to reduce the grinding temperature of DZ4 directional solidification Ni-based superalloy and prevent the grinding burn, based on the calculation formula of grinding specific energy and heat flux density of the arc zone during the grinding process of DZ4 alloy, , A multi-objective constrained optimization method is proposed to optimize the grinding wheel morphology and grinding process parameters when grinding DZ4 alloy, which provides a theoretical basis for the rational selection of these parameters.
