Burrs present a hazard to those who handle parts during and after the manufacturing process. The deburring method can have a major impact on cycle time, cost, quality and customer satisfaction.

Before CNC lathes, single-point threading was a pain in the neck. Fast reflexes were needed to engage an engine lathe's lead-screw dial at precisely the right time and disengage it before crashing into the shoulder. Around the time of the U.S. Bicentennial celebration, tape-operated lathes made all of this headache obsolete.

Within the last decade, multiple endmilling developments have occurred. These include bold, new cutter designs, extremely tough but wear-resistant carbide grades and toolpaths that reduce mechanical shock to machine tool and cutter alike while reducing cycle times by 50 percent or more and extending tool life.

Talk about composites in most machine shops usually refers to carbon-fiber material, though "composites" may refer to a variety of mixed materials going back to the mud-and-straw structures made in ancient times. The latest example: A new metal nanocomposite composed of magnesium infused with a dense and even dispersal of ceramic-silicon-carbide nanoparticles.

CNC machining takes a blend of computer skills and machining skills. Some competent machinists, especially old-timers, lack the computer skills needed to go from print to part using CNC machines. I previously lacked the computer skills, but couldn't tolerate not having complete control of the jobs I was running.

This issue of CTE includes our IMTS 2016 Show Preview, featuring show highlights, information about the various pavilions, a guide to Chicago attractions and an extensive array of announcements about what exhibitors plan to showcase. The latter includes machine tools, software, workholders, automation equipment and cutting tools.

You might think laser pulse lengths measured in nanoseconds—that is, billionths of a second—are short. But they're long compared to those of picosecond (a trillionth of a second) and femtosecond (a quadrillionth of a second) lasers, which are known as ultrashort-pulse lasers.

Our supplier in Asia is grinding hardened-steel parts and sending them to us for final processing. Some of them are cracking, so we're going to visit the supplier. What should we be looking for?

If you're considering implementing a real-time machine monitoring system and looking for solid reasons to make the investment, you're in for a pleasant surprise. Real-time machine monitoring and overall equipment effectiveness software can help address many issues, whether they're obvious or not.

The National Center for Manufacturing Sciences is helping industry develop lightweight automotive parts from nontraditional materials.
