提出了基于特征的飞机复杂结构件切削力预测方法，重点解决侧铣切削力预测的问题。基于特征表达工件局部形状、尺寸以及切削参数等信息，为切削力预测提供充分的支撑；采用解析法构建切削力模型，并通过实验获取相关系数；基于商业CAM软件平台开发并实施了所提出的方法。切削实验结果表明，基于特征的切削力预测平均误差为8.73%，在CAM平台上可实现飞机结构件单个指定特征的侧铣切削力的快速准确预测及评价。

A feature-based cutting force prediction method was proposed herein,which focused on the problem of flank milling force prediction.Partial shape,dimension,and cutting parameter infor-mation were represented based on features,which provided sufficient support for cutting force predic-tion and evaluation.Analytical approach was adopted to construct cutting force model and correlation coefficient was obtained for the cutting force model by experiments.The proposed method was imple-mented based on commercial CAM software platform.Experimental results show that the average er-ror of cutting force prediction is 8.73%,which means that the quick and accurate cutting force predic-tion can be achieved for individual specified features of aircraft structural parts by using the proposed method on CAM platform.
