Aloisi completed her PhD program in mechanical engineering from the University of Padova, Italy.

Beginning some 30 years ago, portable surface finish gages—some small enough to fit in a shirt pocket—brought a new level of part control to the manufacturing floor.

The Hommel-Etamic Toposcan is a system used for measuring the surface of cylinder bores larger then 60mm in dia. 

Air gaging has many advantages as an inspection method. It is quick and easy to use, and requires little skill on the part of the operator.

As part tolerances tighten, both form and surface finish have a bigger influence on the size and function of the product. And with pressures on manufacturing to be more productive, it is no longer viable for checks of surface or form to be performed on a measuring system in a quality room.

How does the surface texture affect the friction between two dry parallel sliding surfaces? It turns out that this problem has challenged some of the greatest minds in science and engineering.

The problem with surface finish is that it gets deep very quickly. Many people talk about the “finish” or the “roughness” of a surface as if it were one unique thing.
