Class of 2014, WW1 Museum CNC Routed Plywood Model.

We had only had the CNC for a couple of months but this project really put myself and the machine through our paces. I could talk for hours about the processes and techniques that went into milling the base, but I’m just going to let the pictures do the talking.

The base was milled from a 1200 x 1200 x 50mm piece of plywood using a .DXF file. The advantage of this compared to a 3D .STL mill, is that the machining time is much much faster, and the surface finish is clean instead of ridged like it would have been using a ball-nose bit.

Milling time was still 6 hours so would only be ever done for students working in large groups to make a site model, but a 3d Mill would have taken around 18 hours and will have had a far poorer surface finish.
