So it is time to replace the surface to gain back some accuracy and consistency in cuts. Of course the nice thing about mechanized processes like CNC, is you can "dogfood" new parts for the machine, with the machine itself! A new table surface is a good example. Here the machine is cutting the zones for the vacuum plenum of the new surface.

When the time comes to remove the old surface, the machine will also assist. I will force the machine to cut through the old surface, cutting into smaller pieces to make for easy removal. The machine helps to repair, as well as destroy itself!
