| Abstract: | The excavator for mill reconstruction of curved NURBS surface and complex surface of hydraulic system of high-speed tary use was discussed. The singularities with local differential geometry property and whole distance property of pipe surface were analyzed. The self-intersection condition and the influence on the pipe surface reconstruction were discussed. The necessary and sufficient conditions for non-singularity of pipe surface were given. The solution to the intersection problem of complex pipes in hydraulic system was put forward |
