This all looks nice so far. However, the path to get there turned out to be a lot stonier than I had expected. The problem is that my mill is acting up badly along the Z axis, reducing the depth by up to almost half of what the CAD model says.
Here is an example. This is what the slices look like in FreeCAD: http://downloads.qi-hardware.com/people/werner/anelok/tmp/dummy-aaa/dummy-aaa-cad.png And this is what came out: http://downloads.qi-hardware.com/people/werner/anelok/tmp/dummy-aaa/dummy-aaa-sizes.jpg The nominal thickness of 17.5 mm yielded pieces between 9.3 and 10.3 mm. The jump from ~10 to ~9 mm may have been caused by setting the depth of the bottom such that the mill would cut well below the floor of the upper MDF block. By the way, double-sided adhesive tape and MDF form an amazingly strong bond, making it quite an effort to pick the slices from the block after milling. The depths of the cut-outs for screw heads are even more puzzling: Nominal Measured Factor --------------- --------------- --------------- 5 mm 3.7-4.0 mm 74-80% 8 mm 5.0 mm 63% 10 mm 5.6-6.3 mm 56-63% Just weird. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
