摘　　要：为了降低难加工材料铣削过程中的加工变形,改善表面加工质量,对加工过程中的铣削力进行预测是必须的。从难加工材料特性及实验现象出发,分别针对端铣刀和球头铣刀将现有铣削力预测方法及其进展进行解析。从现有的研究分析,对于端铣刀铣削力的研究主要集中于切屑形成、最小能量与斜角切削机理,而对于球头铣刀,主要研究微元切削力、刀具接触区域与切屑流动方向对预测结果的影响。从研究趋势上看,对端铣刀和球头铣刀铣削力预测模型理论的研究均有进展,但对铣削过程中状态参数的研究逐渐成为了近年来的研究热点。In order to reduce the machining deformation of difficult-to-machine materials during the milling process and improve the surface quality, the amount of milling force must be accurately predicted. Based on characteristics and experimental phenomenon of difficult-to-machine materials, this paper analyzed the existing milling force predicting method and its progress for end mill and ball-end mill respectively. Based on analysis of current researches, researches on the milling force of the end mill mainly focused on the chip formation, the minimum energy and the oblique cutting mechanism. For the ball-end mill, influences of the differential cutting force, cutter workpiece engagement and chip flow direction on the prediction result were mainly studied. From the perspective of research trends, it makes considerable headway in theory of milling force prediction model for both end mill and ball-end mill. But the study of state variable in the milling process is becoming a hot topic in recent years.
