Manager’s Desk: Inspiration from immigration

There have been days when it was easy to be a pessimist and see the glass as half-empty. But eventually, perhaps when least expected, something provides inspiration and my inner optimism returns. One such event occurred with an employee I'll call "Mario." Manager's Desk Column by Keith Jennings.

Pint-sized precision

If you enjoy the growl of heavy milling cuts, the machine-gun sound of chips striking glass and the heady odor of superheated cutting fluid, a compact machining center might not be the right machine for you. Like I used to, you scoff at phone booth-sized machining centers, with their tiny toolholders and tables not much larger than a 6" machinist vise. If so, you're not looking at the big picture.

Automating thread inspection on tubular goods

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. No shipments occurred in the fourth quarter because the industry experienced a downturn, so capital expenditure projects got cut or delayed, noted Jeff Heath, COO of Autonetics.

3 views of manufacturing

It's been a long crusade for many manufacturers: the battle against an out-of-date public perception of manufacturing as dirty, repetitive work that's possibly unsafe and probably a dead-end career path. Two recent surveys show that there's still a lot of work to do in dispelling that myth, while a third survey is more upbeat.

Low-cost 3D printer for shop operations

A new breed of 3D printers has begun producing parts made of engineering-grade plastics and fully dense metals suitable for long-term use in a variety of applications. These include jet engine components, engine mounts, medical implants and a host of other products that were once machined or fabricated by conventional means. And, compared to earlier-generation machines, the new additive-manufacturing equipment offers enhanced part accuracy and has lower processing times and acquisition costs.
