摘要： 从提高产品加工效率出发，提出并实现了三维自由曲面零件余量加工方法。该方法大大地缩短了粗加工时间，而且留给半精加工和精加工的余量较少，从而使得零件加工整个过程的总效率提高。实践表明，算法稳定、可靠，具有很好的工程应用价值。

Abstract: A rough milling method for compound surfaces is proposed and implemented. The method can reduce the rough milling time greatly while little uncut material need to be cut in semi-finish and finish process, so the total milling time is reduced. The milling efficiency is promoted. It is proved that the algorithm is stable and reliable.
