Material Removal Questions

Question Asked:

I see the question about "... a 5 axis gantry milling machine be considered a robot ..." but the answers seem contradictory. We have developed a XZY gantry for a wood routing Table that we are preparing to inter the market with to consumers. I have contacted UL and they said it would be considered a Robot. When is a machine considered a "Robot" verses a CNC machine? ISO defines it as a machine with 3 or more axis, if that is true then every milling machine would be considered a robot. I came from the machine tool industry which sold plasma machines which were XYZ gantry tables and UL did not consider those to be Robots. So why would a XYZ Gantry be considered a Robot? I can understand it being a Robot if it was a pick and place machine, maybe.
