Looking at the Third Dimension in Surface Measurement

Sometimes the optical system is the best—or even the only—way to measure your surface.

It seems that the subject of 3-D optical surface measurement is all the rage these days.

Form 101

Size matters, but being in shape often matters more.

While John Goodman and Arnold Schwarzenegger are both 6’2”, few would argue that they have similar body shapes. What this says, simply, is that measuring size does not necessarily say anything about shape.

When a Round Peg Is Just Too Square: The Basics of Harmonic Analysis

The technique of Fourier series, or harmonic analysis, has been applied to a wide array of problems, both mathematical and physical.

The latest optical methods for measuring surfaces can be quite adept at measuring difficult to access surfaces.

50 Years of Quality: A Superficial History of Surface Finish

March 30, 2011

Any number of influences can leave their mark on the surface of a part. The result is a microscopic maze of etchings that detail the history of a part’s manufacture.

Shaft Measurement Made Simple

There is growing popularity for a loosely defined class of shaft measuring systems that can accomplish checks faster than other methods, and do so directly on the shop floor where the shafts are made. Frequently used in Europe, shaft measuring systems are gaining U.S. popularity in a number of high-volume applications.

Important Considerations in Error Compensation

Patrick Nugent

November 24, 2008

No matter whether you are interested in a machine tool, a metrology system or another precision device that relies on mechanical motion, what errors of mechanical motion are compensated for and how they are compensated directly impacts that system’s ability to operate at the highest level of capability.
