standar for movements?

I'm trying to set the axis movements for deskwin y-,x-, from
machine "0" is there a industri standar for that?
All the machines atThe place where I work(about7 Kias and one
kytamura) follows the following; Y moving away from operarator moves
in - values(0 to -15),x- moving to the right of oerator(0 to -30).
Y"0" is at operator side,X"0" is at the most left hand side(looking
at the table).


thank's.
