1. A method of autonomously controlling a fluid jet apparatus to cut a target object, the method comprising:
inspecting in at least a first direction and a second direction, by at least one inspection device, a cut of a coupon which has been cut by the fluid jet apparatus moving in a third direction that is perpendicular to both the first direction and the second direction;
receiving, by at least one processor, inspection data from the at least one inspection device based at least in part on the inspection of the cut of the coupon;
modifying, by the at least one processor, at least one cutting process model based at least in part on the received inspection data, wherein modifying the at least one cutting process model includes modifying an orientation of the fluid jet apparatus relative to the target object with respect to both the first direction and the second direction;
generating, by the at least one processor, a motion program based at least in part on the modified at least one cutting process model; and
executing, by the at least one processor, the generated motion program to cause the fluid jet apparatus to cut the target object according to the generated motion program.
