Perfect gaging in an imperfect world
It is certainly not news that, more and more, dedicated gages are being placed at the point of manufacture. Tight-tolerance measurements that were once performed in a semiclean room by a trained inspection technician are now being done right next to the machine, often by the machinist. But just because shop floor gaging has become commonplace, doesn't mean that just any gage can be taken onto the shop floor. To assure good gage performance, there are a number of specifications and care issues which need to be addressed.

URI capstone project facilitates hands-on learning for engineering students
Mahr Inc. has partnered with the University of Rhode Island's (URI) engineering department to offer students the opportunity to work on real-world engineering and manufacturing problems. As part of the URI capstone project, students in their senior year are selected to take part in a year-long capstone project focused on automation of submicron precision finishing of ring gages.

Measuring straightness in small metal parts
When seeking straightness, as well as parallelism, perpendicular end cuts and other important geometric dimensioning and tolerancing features, the goals at Metal Cutting Corp. are cost-effectiveness and high-quality, tight-tolerance parts. To that end, the company finds that using qualitative test methods for straightness and other features consistently helps keep production costs under control while delivering the results that customers need.

A here-and-now gage
The Heidenhain Specto 3087 RC length gage reportedly increases productivity and efficiency, particularly in applications where it's not possible to clamp the workpiece on a separate device to inspect it. Instead, the gage integrates a highly accurate measuring process directly into the production process.

Manufacturer simplifies its inspection processes
Like most of us, Jay Hegemann deletes a lot of emails every day. Everything from miracle cures for baldness to special offers from credit card vendors go right into the trash. However, something about the email from Keyence's sales engineer earlier this spring caught Hegemann's eye and he decided to take another look. It's a good thing, because the product advertised in that message has been a game changer for this small manufacturing firm.

Machine Technology: Manually measuring 5-axis centerlines
In 5-axis machining, accurate rotary axis centerlines are critical, so regularly measuring and verifying these values is also critical. While the best course of action is to measure the machine using a high-tech system intended for this purpose, in a pinch you can use a manual process.

Reaching new heights
Measuring machined parts on a surface plate has long been a tedious job, one that requires mastery of dial indicators, a pocket calculator and an adjustable height gage that most in the industry refer to as a "Cadillac gage." But several metrology providers offer a more sophisticated way to quickly and accurately check hole diameters, the distance between part features, centerlines and more. The tool is called an electronic height gage, and it has made Cadillac gages about as popular as whitewall tires.
