safety
   training

assignment
   group assignment
      do your lab's safety training
      test runout, alignment, fixturing, speeds, feeds, materials, and toolpaths for your machine
   individual assignment
      make (design+mill+assemble) something big (~meter-scale)
      extra credit: don't use fasteners or glue
      extra credit: include curved surfaces
