摘　　要：铣削加工表面粗糙度的形成与铣刀和工件振动、主轴偏心、刀具磨损、刀具变形等物理和几何因素有关。多年来中外学者针对各种影响因素建立了“相对单一”的数学模型。这些数学模型只考虑了一种或两种影响因素,还没有建立起描述物理和几何变化过程的综合数学模型,为此对这些相关因素进行了深入研究,建立了基于球头立铣刀的铣削加工表面粗糙度仿真的整体数学模型。从而为虚拟数控加工仿真提供技术支撑。The surface roughness in mill machining relates to quiver of work piece, principal axis＇ s eccentricity, cutter abrasion, cutter distortion and other physical or geometry factors. In the past years, more China and foreign countries＇ scholars have build the ＂ relatively singleness＂ math mode contrapose each factor. But this math mode only considered one or two factors, and has not built the integrated math mode, which can describe the physical and geometrical change process. So, The made a further study of these factors, and build the surface roughness simulation integrate math mode in mill machining based on ball head milling cutter. Then provide the technical support for virtual NC simulation.
