Compact Cutting

Waterjets are an investment, not only in cost, but in shop floor space. Machine shops often utilize mills, lathes, multi-axis machine centers, grinders, EDM machines and precision hones. The goal of any shop is to add value to a product through the manufacturing process. A shop only has so much floor space to work with, and choosing the right tools to maximize efficiency is an art. Potential...

Bringing real-world metal fabricating to college

Today’s engineering students are bright and very good conceptual thinkers. Jensen said that where they might fall short is in the hands-on experiences of actually building things and rebuilding them when they don’t quite work. But engineering labs like Oregon State’s are designed to help introduce them to the real-world technologies that make the computer work a reality. That’s been a little...

Cutting versatility a must at custom boat shop

Founded more than 20 years ago, Titan Boats, based in Sidney, B.C., initially focused on manufacturing vessels for the ecotourism industry and governmental agencies in Canada. In 2015, amidst growing demand, the company embarked on a plan to diversify and expand its product line. As a result, the shop needed new, adaptable technology to boost capacity, efficiency, and production capabilities...

Abrasive Cuts

Titanium is the preferred material for components in a variety of demanding applications. Due to its light weight, strength and hardness over traditional materials like steel, as well as beneficial properties such as corrosion resistance, titanium is the material of choice for many industries including aerospace, defense and medical. However, machining titanium is known for being a very slow...

Waterjetting: Get on script

Customization often starts with the question, “Is there an easier way to do this?” A manufacturer might need to change its clearances on a series of part files by a fraction of an inch. A prototype shop could look to integrate a robotic arm for loading material. A fabrication shop may have to guarantee the alignment of an upcoming order.

The answer...

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...
