Tutorial – Preparing your model in Rhino for CNC milling (From 3D model to CNC fabrication, part 2)

This tutorial showcases an example of preparations in Rhino to make your model suitable for CNC milling, in the context of aiming to utilize the CNC router in the KTH Architecture school Workshop. Timestamps: 0:00 You want a single closed solid polysurface, identical to what you intend to mill 1:12 Adhering to the limitations of three-axis CNC milling 1:30 Good procedure to work in a separate file, and necessary to work in mm 1:43 Scale the model to its intended fabrication scale 2:46 Make a stock bounding box, reflecting the height of the milled material 4:32 Straight method of converting open polysurface to closed and solid 5:16 Tapered method of converting open polysurface to closed and solid 10:44 Achieve a rotation of the model so that the entailing stock bounding box is material-efficient, as well as corresponding with the orientation of the axes of the CNC machine 12:58 Offset the lateral sides of the material stock, to give more headroom for placement errors during mi
