摘　　要：分析了平面二次包络四轴四联动数控磨床的加工工艺原理,根据该原理及机床结构建立了坐标系,推导出各个相对坐标系间的齐次坐标变换矩阵,创建了理论状态下的加工数学模型,基于刚体假设建立了影响加工精度的数学模型,讨论了影响加工精度的主要因素,提出了解决方案。The processing theory of the plane-quadratic-envelope four-axis-linkage grinding machine was analyzed, based on the structure of the machine tools, the coordinate systems were set up. The ideal processing model was build based on the homogeneous coordinate transformation matris between the relative coordinate systems. Using the rigid-body assumption, the reasons affect the cutting precision were discussed, the solving method was introduced.
