I know the HSS cutters can deflect, but no WAY can it deflect even .050" (half your error). Could the workpiece be slipping on the table? Could the head of the machine be swinging on the round ram (if it is built like that?) Why not cut one side and then go back and re-check the initial coordinate setup at the corner? That will detect part slippage.
And, of course, if this is a stepper machine, check for loss of steps after a long program.
