CNC double spiral tool-path generation based on parametric surface mapping ?
We study a new double spiral tool-path generation algorithm for 5-axis HSM. We call a smoothness optimization method during solving PDEs to smooth curves. Machining parameters (e.g., path interval and step length) can be guaranteed. Mapping rules are based on the same ranges of NURBS curve and parametric domain. Our tool-paths have a self-complementary structure and can be suitably linked.
