Main Ideas of CNC routing

Main Ideas CNC routing

  • To CNC a model, your object needs to be able to exist in a tangible, stagnate world that is not virtual. Meaning that it is a closed object, that has a thickness, it is not a render. It is a representation of a real world thing.

  • Properties of appropriate "real world" model.

    •  Surface Integrity
      • Considered as solid material
      • Water tight
      • No naked edges.
      • No missing surfaces/holes
      • No manifold surfaces
    • Thickness (Object integrity)
      • Object integrity, responding to material constraints
      • Ability to withstand force (gravity, touch.....)
      • Scale, footprint and foundation
    • Appropriate "wall thickness" to withstand the force of the milling end mill. 
      • No wall thickness can be under 1/4" (.25")  in your model.
    • Formatting model for CNC output.



CNC router (Or Computer Numerical Control router) is a computer-controlled cutting machine related to the hand held router used for cutting various hard materials, such as wood, composites, aluminium, steel, plastics, and foams.
