摘要
结合刀具磨削的特殊性和计算机数值计算的优点．提出了一种适合于复杂形状刀具CNC磨削的数学模型──刀刃点跟踪CNC磨削法。该方法由于充分利用了刀具加工的特殊性．并且将空间解析几何、优化设计及数值计算等方法有机地结合在一起进行求解，不仅求解速度快，而且求解精度高。通过在计算机上的计算及磨削过程仿真表明，该数学模型可生成高精度的刀位（CL）数据．并可有效地应用于实际加工中。
Based on the peculiarity of tool grinding and characteristics of numerical computation by computer, a mathematical model, cutting cdge point following (CEPF) CNC grinding method that is applicable for CNC tool grinding is proposed. With making use of the peculiarity of tool machining. combining organically with spatial analytic geometry, optimal design and numerical calculation, the solution of tile proposed model is found rapidly with high pecision. By solving and simulating by computer, the model is solved and high-pecision CL-data are gotten. It can be used to tool production practically.
