Abstract

An abrasive jet apparatus configured to machine features into an inner diameter of bored structures. In the abrasive jet apparatus, an abrasive mixture of pressurized liquid and abrasive particles is propelled as an abrasive jet in a direction other than the direction in which the abrasive jet apparatus extends. The abrasive jet apparatus may be implemented in an automated boring system and boring method for machining rifling grooves and other features into bored structures. The boring system and boring method use an iterative process of mapping a target surface of the bored structure and adjusting parameters of the boring system in between successive passes of the abrasive jet on the target surface.
