Axis Directions

Hi just found this on fleabay for a Boxford mill

Shows the directions table and head should move in(I think)

Only problem is Denfords started off wrong, they decided that their way was best and because this was based in education Boxfords had to follow or be odd man out and it's a case of it's stuck.

Industry uses X and Y opposite to this and all industrial text books CAM programs etc all work this was.

Not sure I understand why industry is going to be different.
If I want to machine a part from an industry standard drawing in which the origin is bottom left at 0,0 then I want to machine 0,0 to 1,0 then on my mill the table will move to the left as the head cannot move as on a gantry, so to my mind denford is correct.

Never equate bed movement with direction.
It's always tool movement.

This way all axis move the same.
Denford's way means the bed moves in X and Y but the head [ tool ] moves in Z
