Rhino Grasshopper - Create Tool Paths for CNC Routing
Main Topics
Extracting BREP Wireframe / Edge Curves
Dividing Curves
Finding the Closest Point on a surface
Evaluating a surface at a parameter
Creating / Translating Iso-Curves
In this Grasshopper video tutorial we will be creating different patterns of Iso-curves that have the potential to be used as toolpaths for CNC milling machines. In this first version of the exercise we'll create a "parallel cut" pattern on the surface by extracting parameters incrementally along one edge. We will then modify the "parallel cut" pattern to be affected as the surface climbs / descends in the Z value. This video encourages designers and students to design not only the parts, but also the fabrication techniques. Generating G-Code is not covered in this video. Video by Michael McCune. As always, please let me know if you questions and/or inquiries.
