Abstract
The invention describes a method and apparatus for milling objects by means of high velocity abrasive waterjet. The apparatus includes means for holding and producing relative motion in three dimensions of both the workpiece and the jet. Control means are provided to allow uniform and variable depth milling of complex shapes and automatic variations in relative speed, standoff distance, angle and pressure. The method includes the use of a resistant mask for facilitating milling and production of masks by the same tool used for milling.
