Fundamentals of Waterjet Cutting: Optimum Efficiency

While most users of abrasive waterjet cutting profess its ease of use, anyone that owns a waterjet will admit that while cutting a one-off part might be easy, producing thousands of the same part, with 0.05-in. tolerance, requires knowledge and skill. The difference comes down to understanding process fundamentals and how they work together. Let’s examine a few fundamental tips to help...

Meeting Standards

Choosing the correct tools can be the defining factor in a true representation for testing. In an ideal scenario, testing preparation shouldn’t impart any additional changes to the original material but many traditional cutting machines leave residue or distort the material.

As stated in ASTM E8/E8M–13A under Subsection 6.1.3, “Improperly prepared test specimens often are the reason...

Right On Track

It’s almost certain that everyone has seen or stood on Mondo rubber flooring, whether they know it or not. It’s used for track and field surfaces in the Olympic games, and it’s installed in professional sports venues, academic athletic facilities, gyms and even hospitals around the world. In fact, the flooring manufacturer is currently the official supplier of athletic tracks for the Olympics...

The pressure behind abrasive waterjet cutting

Since the inception of waterjet technology nearly 50 years ago, there has been an ongoing argument concerning what combination of pressure and power results in optimal cutting performance. Do bigger numbers translate into better or faster cutting? What combination of pressure, horsepower, and nozzle assembly is best for a given application? What does all this really mean?

Third Dimension

For a fabrication shop, versatility is key for taking on as many jobs as possible. The more often a shop can say “yes” to potential jobs, the more successful they will be. The easiest way to achieve greater versatility is by expanding capabilities. Shops that focus primarily on flat 2D work, for example, can add an articulated cutting head and/or rotary axis to...

New chapter

Metal asteroids? Most are made from rock or ice but in recent months, NASA approved the next fabrication and testing phase of its spacecraft and subassemblies for its mission to explore Asteroid Psyche, an asteroid scientists believe to be metal. It originates from a planet possibly as large as Mars. It is voyages such as these that innovate technology that then flows down into everyday...

A Nepalese Gristmill, a Waterjet and Fort Lewis College

Waterjetting isn’t new to stone fabrication, though it is still not the norm. Due to being quick, accurate and safe, waterjets are starting to be featured more in stone shops working in the custom architectural and design fields. From granite to Dekton, abrasive waterjet is perfect for cutting chip-free countertops, intricate medallions, beveled edges, straight cuts and geometric arcs. Common...

Generative Design and the Conventional Machine Shop

The term generative design has been popping up in the manufacturing world of late. Its promise is to create many design permutations to let engineers choose an optimum one that meets sometimes conflicting requirements.

The problem is that many of the designs that result from using generative algorithms are complex, even organic looking, with complex curves and webs. This has led to a...

Barriers to Industry 4.0 Are Falling Fast

For years, manufacturers of all sizes and across every industrial segment have heard about Industry 4.0. The definition changes depending on the speaker or publication, but the essential idea remains the same. Now that manufacturing has become almost entirely digitized and interconnected as part of what we might call “Industry 3.0,” shops and their suppliers have begun to leverage digital data...
