On a piece of paper, one might draw a graph, with X0Y0 being at the bottom left.
And it looks like, and this is my query, most CNC machines use X0Y0 at the front left of the table? I have an old KTF-30 King Tun Fu drill-mill that I use a lot. But on this machine, X0Y0 is at top right, as in rotating your graph paper 180deg on the table. Since most people use a vice on a milling table, what is great about this arrangement is that the fixed jaw, and not the moving jaw, is my default reference. So if I want to drill holes in a plate, I simply position the edge flush with the right of the jaw, and the right edge of the fixed jaw is my 0,0 Alternatively, my Y0 is always the inner surface of my vice's fixed jaw. Since machines and especially CNC machines don't care about orientation of axes, why isn't this axis orientation more common? Or is it? Obviously this pertains to general milling where the edge of the vice is sufficient as reference.
