Abstract
A liquid abrasive jet focusing tube for making cuts in a workpiece at a predetermined non-perpendicular angle, and a method for making non-perpendicular cuts in a workpiece with a liquid abrasive jet. The focusing tube includes a body having an inlet end which defines an inlet opening, an outlet end which defines an outlet opening, and a cylindrical passage which extends between the openings and which has a longitudinal axis. The outlet end has a tip portion with an angled surface adjacent the outlet opening and oriented in relation to the passage axis at the predetermined non-perpendicular angle. The method includes positioning the focusing tube so that the angled surface is generally parallel to the workpiece surface and the passage axis is oriented in relation to the workpiece surface substantially at the predetermined non-perpendicular angle.
