I will add that it appears that the tables are made from ali so it ain't gonna last long.

As Jonathan mentioned to do 3d , cam software is expensive.

When doing 3D the software i use is able to rough out using large cutters then doing REST machinning using smaller cutters to get efficient toolpaths.

On a shape i programmed which was in your work envelope the machining time was in the order of 18 hrs this was using a roughing toolpath so even longer using a single smaller cutter.

Good Cam software can cost £3K +
