Numerical Control Milling Machine Toolpath Generation for Regions Bounded by Free Form Curves and Surfaces | The search for strategies and methods to automatically generate toolpaths for Numerical Control (NC) machines from mechanical parts modeled by computer aided solid design systems has met with only limited success to date, mainly in applications to simplified models. Problems that occur when the exis... | computer graphics; computer-aided design; numerical control machines; toolpath generation | 1989-06 |
