摘　　要：分析了平面二次包络四轴四联动数控磨床的加工原理,根据该原理及磨床结构建立了坐标系,推导出了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数控加工数学模型,并采用基于CDK6150数控车床改造的平面二次包络四轴四联动数控磨床进行切削实验,设置平面二次包络蜗杆参数,编写数控加工程序,验证了其加工原理的正确性。The coordinate system is set up based on the machining theory of the plane-quadratic-envelope four-ax- is-linkage CNC grinding machine and the structure of the grinding machine. The ideal processing math- ematical modeling is built on the basis of the homogeneous coordinate transformation matrix between the relative coordinate systems deduced from the coordinate system. Cutting experiment is conducted on the plane-quadratic-envelope four-axis-linkage grinding machine reformed from CDK6150 lathe. During the experiment, plane-quadratic-envelope worm parameters are set up, machining programs of CNC are written and the correctness of the machining theory is verified.
