Abstract

The invention describes a method and apparatus for peening objects by means of ultrahigh velocity 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 peening of complex shapes and automatic variations in relative speed, standoff distance, angle and pressure. The method includes the use of entrained disappearing particles in the waterjet to facilitate peening.
