Q&A with Marc Strandquist

What did you see coming that helped you map out the future of Optimas Solutions Americas’ market? There were a lot of unfinished projects, but...

Introduction to nondestructive testing

Nondestructive testing (NDT) is an interdisciplinary science that uses many different methods to evaluate the properties of metals, parts, or assemblies without causing damage...

Fracture mechanics and fatigue crack growth

In the last article, we talked about fracture mechanics, and the method of fracture toughness testing using fracture mechanics. In this article, we are...

Q&A with Daniel Weis

How long have you been with Neugart and what are your responsibilities? I started my career with Neugart in 2005 as a young mechanic apprentice...

What, precisely, is my gear made of?

The building blocks for all materials are microstructures known as atoms. Whether the material in question is a plastic, a metal, or even your...

Mechanical paste polishing vs. CAVF finishing of gears

A recent Materials Matter article compared generic deburring versus CAVF (chemically accelerated vibratory finishing.) Both techniques are conducted in a vibratory unit. The main advantage of...

Precision gearing: Accuracy and tolerances

When I was a child, one of the great joys of going on the family vacation was to pull out a paper map and...

Back to basics – Fracture toughness testing

In previous articles, we have discussed the many different types of mechanical testing methods and requirements. While some of the test methods have application...

Q&A with Stephen Korosec

What does the Koro Sharpening Service offer the gear industry, and how long have you been in business? We sharpen only gear cutting tools. Most...

Determining tooth thickness of various gear types – Part III

In order to determine the tooth size of a gear after taking into account the backlash allowance, you first must determine what the nominal...

Back to basics – Toughness testing of material

In the last series of articles, we discussed hardness testing and tensile testing. In these applications, the loading is a static load over a...

The challenges of generic deburring vs. CAVF deburring

Relative to gear hobbing, shaving, and/or post heat-treat grinding to generate accurate tooth morphology there may come a time wherein vibratory deburring is a...

Q&A with Aaron-Michael Eller
