Cortar Placa com a Fresa CNC

Feliz Natal!
Mais uma boa notícia da Ponoko, o Plug-in da Grassshoper, para o programa 3D Rhino, permite-vos cortar placa na vossa Router 3D, mas tendo em conta as dimensões da ferramenta de corte.
Por isso, ter uma Fresa CNC permite. agora, cortar placa como se tivessem uma cortadora CNC a Laser!


Tutorial CNC routing with Grasshopper

Parametric software can save you a lot of time by automating repetitive tasks. The Grasshopper plugin for Rhino is well known for its impressive generative architectural modelling, but it is also useful for much simplier tasks such as offsetting lines as you might do manually in Illustrator or inkscape for CNC routing.

CNC routing is slightly more complicated than making linework for lasercutting due to the radius of the material that is cut away. (With lasercutting the laser is so fine, you don’t really need to worry about the radius of material that is cut away. This is why I’ve made a very basic Grasshopper definition file that demonstrates how you can automate the offsetting of lines for the radius of a router bit cutter to see how your design will look once it is cut out.
