Video: Additive Manufacturing of Metal Matrix Composites for High-Hardness Parts

NanoSteel produced the video here, as well as this related video, to describe its recent success at applying additive manufacturing to build high-hardness ferrous metal matrix composite parts. The metal matrix composite in these builds combines steel in two phases, a hard phase embedded in a ductile phase. Achieving this combination through laser sintering permits parts with high hardness to be additively grown without the cracking that often hinders additive manufacturing of hard steels. NanoSteel sees this success opening the door to additive manufacturing of cutting tools, bearings, dies and downhole equipment. Read more from the company here.

Video: From 2D to Five-Axis

Loading the player ...

Waterjet technology is well-suited to cutting large 2D workpieces out of sheets of material, but Jet Edge’s Edge X-5 demonstrates how a waterjet can effectively cut three-dimensional parts as well. The waterjet’s five-axis Permalign Edge cutting head enables it to produce features such as weld bevels and countersink holes, as well as reduce tapering in the jet stream. The waterjet offers a Z-axis travel of 12" and is available with a work envelope ranging from 5 × 5 feet to 24 × 8 feet.

In the video above, the Edge X-5 is cutting Jet Edge-branded bottle openers out of 1/4"-thick aluminum using 80 mesh garnet abrasive. The piece showcases the waterjet’s five-axis capability with features such as the angled “Jet Edge” lettering and the chamfering around the outer edges.

JIMTOF 2014: Our Industry’s Next Big Show

Tokyo’s Big Sight, home to JIMTOF, is truly an eyeful, with the dramatic architecture of its Conference Tower dominating the exhibit hall entrance area. 

As a global leader in machine tool design and construction, Japan plays a key role in developing and promoting new metalworking technology. The Japan International Machine Tool Fair (JIMTOF), packs a lot of product introductions and educational events in a compact, intense event running October 30 through November 4, 2014. Look for daringly imaginative designs in machine tools and related products at Tokyo’s eye-catching Big Sight exhibition center.

Plan to attend now starting here.    

The theme for this year’s show is Mono-Zukuri DNA. Loosely translated, that phrase means “an inspired approach to the art and science of making things should be at the core of our beings.”

Do Your Kids Know What You Did at IMTS?

Sandvik Coromant used the recent International Manufacturing Technology Show as an opportunity for outreach to the next generation of manufacturing professionals. The cutting tool maker funded a virtual field trip to IMTS consisting of three video episodes that were filmed at the show, edited at the show and broadcast to 200 schools while the show was underway. Find links to all three episodes below. Consider sharing these episodes with the kids in your life, particularly if it helps them understand where you go and what you see when you make your own trip to IMTS.

Called “Technology Applied,” the IMTS virtual field trip was hosted by Jeremy Bout of Underhouse Studio. The still above, from the Automotive episode, shows Mr. Bout talking to Derrin Barber of Doosan in this company's booth. Here are links to the episodes:

All of these episodes are part of a new microsite full of resources for helping kids understand and pursue careers in manufacturing.

Video: Applying “Dengeln” for Finishing Turbine Blades

You might know “dengeln” to be a peening method of smoothing and sharpening the blades of scythes or sickles via manual hammering. Starrag says it has developed on-machine dengeln technology that uses an electrically powered tool to finish turbine blades after machining to a roughness value of just 0.2 micron Ra.

The process uses a tungsten tool with a spherical tip pulsed to 600 Hz that repeatedly impacts the blade surface and changes the original structures of surface boundary layers to a depth of 10 mm. This capability offers the possibility to eliminate secondary polishing, grinding and shot peening to finish blades. It can also eliminate manual polishing for dies and molds.

The video above shows one of the company’s five-axis LX 051 machines performing the dengeln process to finish a typical turbine blade after machining.
