On the basis of STL slicing, slicing data is interpolated by three degrees subsection NURBS curve. After CL data is computed through CC data, the NC tool path planning is realized.
在STL切片的基础上,对切片数据进行三次分段NURBS曲线插值,通过刀触点计算出刀位点,实现了数控加工路径的规划。
Finally, CL data transformed to NC code through post-process. Then the theory and algorithms are proved to be validity through putting the the results into the practical 5-axis NC machining.
最后,对刀位文件进行后置处理,将课题研究中提出的理论和算法应用到了叶轮的加工中,通过在五坐标数控机床上对实际工件的加工,验证理论分析的正确性。
