摘　　要：在侧铣淬硬钢试验的基础上,研究小直径铣刀侧铣时刀位路径曲率对铣削力影响,建立了小直径铣刀铣削淬硬钢的切削力与刀位路径的灰色模型并进行预测。预测结果表明,此模型有很高的预测精度。同时揭示刀位路径在不同曲率半径下切削力规律,寻找减少小直径铣刀加工淬硬钢时非正常破损的有效途径。On base of side milling hardened steel test,study of micro-end mill of hardened steel milling tool path of curvature on the impact of milling force. And the same time ,establishing the gray model of the milling force and tool path of curvature in the process of milling hardened steel,and predict it＇s force. The results show that this gray model may get high precision. Also discovering the law of force in milling in the radius of curvature by different path. At last,seeking an effective way to reduce the nonnormal damage of rnachining hardened steel by micro-end mill.
