Calibrating a multiple-axis machining center is one of those time-consuming but necessary tasks that parts makers have to accept. The task has gotten easier in past years, however, and has just gotten easier yet.

Thread cutting is as close to artistic expression as one typically gets in a machine shop. Watching a machinist or toolmaker peel off perfectly formed chips with a precisely ground tool is mesmerizing.

According to Autonetics LLC, automated gaging units (AGUs) for threads are hot. The Cary, N.C.-based AGU manufacturer reported that it shipped 10 systems in the third quarter of last year to U.S. pipe mills that produce oil country tubular goods.

Highlighting the benefits of modular metrology fixtures versus traditional methods, this brief video covers the differences in set-up times, ease of set up, inspection repeatability, part stability and metrology accuracy.

Livonia-based Michigan Metrology will host a short course on surface metrology and tribology on May 9-10. Dr. Don Cohen, an expert on surface roughness and its effects, will lead the course. Topics to be covered include instruments for measuring texture, surface texture parameters, wear, friction, sealing, data analysis and more.

Where is the field of inspection headed and, more importantly, where do the manufacturers that depend on it desire it to head? In 2014, the Coordinate Metrology Society (CMS) combined forces with the University of North Carolina-Charlotte to find out.

Hassay Savage, which manufactures and supplies micro cutting tools such as broaches, round tools, reamers and drills, was searching for a new method of qualifying its micro cutting tools when company owner Robert Savage watched a demonstration of the Zoller Inc. »pomBasicMicro« at an American Gear Manufacturers Association event.

Around for more than 100 years, air gaging is a mature technology that still has a place in modern shops.

As the plans for more and more machined metal parts include numerical surface finish specifications, the need diminishes to visually qualify that a part has, for example, "a mirror finish with no burrs" or to have the machinist with the finest touch scratch the surface with his fingernail to make sure it's "matte and rough."

Hexagon AB, a global provider of information technologies for driving productivity and quality across geospatial and industrial enterprise applications, today announced the acquisition of AICON 3D Systems, a leading provider of optical and portable non-contact 3D measuring systems for industrial manufacturing.
