How do I interpret accuracy

on 2004-03-25 20:27:25 UTC

Hi everyone.
Please help me understand what the accuracy of a machine really is.
The Taig specifies its accuracy as "exceeds 0.0005inch" while
CNCMaster's CNC Jr has accuracy of "+/-0.003inch in 12inch".
While I can understand the meaning of "+/- 0.003inch in 12 inch"
(seems more like maximumm error), I have difficulty in
understanding "exceeds 0.0005 inch".

TIA for responding to my dumb question.
