Notes (from Bednark Studio):

  1. This thinner material is very difficult to hold down with vacuum.  We used tabbing to prevent the parts from moving.  Once most of the machining was done, the machine removed the tabs.  Please refer to ‘MasksV3 - 27 per sheet nest TABBED.MCX-7’ to see how we accomplished this. 
  2. The matching NC file is the program Bednark Studio is running on their Cut Center.
