Comparing Motion Control Systems in Abrasive Waterjets

Positioning accuracy is a critical aspect of producing tight tolerance parts when cutting with an abrasive waterjet. The more precisely you can position the jet, the more precisely you can machine the part. A motion control system positions the cutting nozzle along the X- and Y-axes of a waterjet. This system is comprised of motor and drive components, a controller and optionally a position...

Controlling Taper

Types of Taper Inherent to Waterjet Machining

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...

4 Piercing Methods In Abrasive Waterjet Machining

Abrasive waterjets make it easy to quickly cut precise parts from almost any material. How the machine pierces the material affects the overall production time and resource usage. Several piercing methods have been developed to deliver optimized cutting for various material types, thicknesses and part geometries.

#1 Stationary Piercing

This is the simplest and earliest piercing method...

The Whole is Greater than the Sum of the Parts

When someone looks at adding an abrasive waterjet to their shop, there are many points to consider, such as the size of the machine and the operating requirements. Ultimately, though, it comes down to one thing: money. Whether saving it or making it or a combination of both, money is the dominant concern. With so many variables surrounding abrasive waterjet systems, it is easier for...

OMAX Waterjet Technology Is Key to Healthier Soles

Turning concepts upside down and inside out to make a better, healthier product is what OESH is all about. The Charlottesville, Virginia company has revolutionized shoe manufacturing by designing a responsive sole integrated with the rest of the shoe in a unique way that ensures the foot always encounters a perfectly level surface.

OESH shoes, the brainchild of Dr. D. Casey Kerrigan,...

Did you know pure waterjets and abrasive waterjets are not interchangeable?

Waterjet machining has been around for decades. In fact, it is one of the fastest growing machining processes today, mainly due to its high versatility and ease of use. But when it comes to waterjet machining, there are actually two distinct types, pure waterjet and abrasivejet, and understanding the difference is important, if not critical.

Pure waterjet is the original form of the...

Abrasive Waterjet Technology: Fast, Accurate Parts Production Starts Here

Abrasive waterjet machines require minimal fixturing, offer quick setups and make it easy to go from idea to finished part in no time. Attributes that many manufacturers see as a winning combination for prototype development. And, while this is true, it creates the perception for some that these machines are best suited for single-piece or niche applications. But nothing could be further from...

Waterjets Move into the Mainstream

Manufacturing Engineering April 2005 Vol. 134 No. 4

Robert B. Aronson, Senior Editor

Waterjet is said to be the fastest growing manufacturing technique. But can a process that's good at cutting chicken parts do anything for you? Quite possibly, yes.

Waterjet, in a single machine, can greatly extend the manufacturer's capabilities. The buyers of waterjet systems seem...

Waterjet Goes Mainstream

by Charles Bates

Cutting with water? Not as wild and wacky as some might think.

Abrasive waterjet has never been considered a run-of-the-mill machining technology. In its early days, shops thought it weird, typically using it only as a last resort when all other cutting methods failed. As if this wasn't enough of a setback, the process had problems with accuracy, reliability, and...

The Engineers' Guide to Designing Abrasive Waterjet Parts

This is intended to give some tips for Engineers who are not experts in abrasivejet machining, but may be designing parts for Abrasivejet Machining. Hopefully, some of the tips and ideas presented here will save you time, effort, and money.

Quick Tips:

You can machine virtually any 2D shape. For cheaper / faster parts: avoid sharp corners, or tight radii. Avoid tiny holes in...
