KENT, Wash., July 18, 2017 - OMAX® Corporation, a designer and manufacturer of computer-controlled abrasive waterjet systems, has produced the world’s most precise micromachining abrasive waterjet available with the assistance of a Small Business Innovation Research (SBIR) grant from the US National Science Foundation (NSF).
The NSF SBIR program is a highly...
The abrasive waterjet cutting tool consists of millions of tiny abrasive particles. All those particles are accelerated in the nozzle and perform the cut one impact at time. Depending on the cutting conditions, geometry of the cut, the material and other parameters, the cutting edge can take on different shapes that are commonly referred to as taper. A V-shaped cutting kerf will produce a part...
In waterjet machining, taper refers to a difference in the kerf width at the top of a cut and the kerf width at the bottom of a cut. A typical waterjet cut has a slight taper, the most common type being V-shaped taper. This type of taper is generated because the jet stream loses some of its cutting energy as it cuts deeper into the material...
A tilting head angles an abrasive waterjet’s nozzle as it moves along the cutting path, resulting in a taper-free cut. This paper offers insight into the product development process of this innovative concept — a mechanism that allows the nozzle to tilt about the jet entry point with minimal compensation motions in the X, Y and Z direction. Tilting and compensation motions are...
