1. A method of changing a bore profile of a bore of a bored structure, comprising:
receiving first data indicating an initial bore profile of the bored structure and second data from an input device indicating a desired bore profile of the bored structure;
rotating one of an abrasive jet apparatus and the bored structure about an axis of rotation relative to an other of the abrasive jet apparatus and the bored structure;
positioning the abrasive jet apparatus within the bore of the bored structure; and
responsive to the first data and the second data:
(i) moving the abrasive jet apparatus along a first direction within the bore of the bored structure, wherein the first direction is a direction along or parallel to a central axis of the bore,
(ii) controlling a rate of rotation of the one of the abrasive jet apparatus and the bored structure,
(iii) directing an abrasive mixture as an abrasive jet from a nozzle portion of the abrasive jet apparatus in a second direction different than the first direction, the abrasive jet forming a recess on a target surface of the bore of the bored structure, and the abrasive mixture is a mixture of a pressurized liquid and abrasive particles,
(iv) measuring dimensions of the recess formed on the target surface using a non-contact sensor,
(v) determining whether the measured dimensions of the recess are acceptable based on the desired bore profile of the bored structure, and
(vi) if the measured dimensions of the recess are determined to be not acceptable based on the desired bore profile of the bored structure, repeating steps (i)-(iii) to adjust one or more dimensions of the recess on the target surface.
