机械制造中常遇到回转体相贯的情况，特别是在管路加工中。如何准确加工回转体的相贯线是精确制造及保证性能的关键，而相贯线求解中，极值点的求解至关重要。文中针对柱、锥相贯线极值点给出了数学求解模型，并按此模型构建了相贯线最右点投影方法。

The intersection phenomenon often occurs during the process of making the axisymmetric body, especially handling the pipeline, h is the key to fabricate the precision goods and guarantee the performance that can handle the intersection body precisely, However it is the most important to solve the extreme points about the solving the intersection body. Tile mathematic model of the intersection extreme point between the cone and the column is built. The final right point projective method is presented.
