Machining Glass with Abrasive Waterjet

The abrasive is accelerated by the jet and as it hits material, the abrasive erodes the material. Computer controlled pressure and abrasive flows eliminate cracking during the piercing cycles. For example, 1/4 thick glass can be machined by abrasive waterjet at speeds of up to 120 inches per minute using 55,000 psi pressure and a 0.015 orifice.

Keywords: Abrasive water jet machining, Kerf tapper ratio, Surface roughness, Fiber reinforced composite materials, Abrasive materials INTRODUCTION Nature has taught that even the hardest rocks can be eroded by a stream of water and moved away from the

High Pressure Water Jetting

Since AWJ machining involves the interaction between the Abrasive-water slurry jet with the material, the jet energy decreases at the exit side of the cut. This leads to low cutting ability of the abrasives near the exit side of the jet and hence, a tapered cut is obtained.One of the challenging issues in AWJ machining is to optimize the process to reduce this taper.
