A video tutorial on lasers from Ronald D. Schaeffer, Ph.D., the chief executive officer of PhotoMachining Inc. Schaeffer provides the history and future of laser technology and its importance in micromanufacturing.

Episode 60 of the Grinding Doc Video Series involves a shop that was cylindrical grinding a 50mm diameter part that proved to be out of spec despite in-process gauging that showed otherwise. About the Grinding Doc Video Series: Thanks to his work as an independent grinding consultant and the author of the "Ask the Grinding Doc" column in Cutting Tool Engineering magazine, Dr. Jeffrey Badger routinely receives questions about grinding from shops all over the world. Through the magazine column and this video series, he provides shops with the insight and guidance they seek.

Posted as a supplement to "Variations on a theme," a feature article published in the June 2015 issue of Cutting Tool Engineering, this video shows Millstar's indexable-insert milling tools machining aluminum. Tried-and-true aluminum alloys continue to do the job for multiple applications, and toolmakers have enhanced their offerings to more effectively machine a metal that's generally considered easy to cut. One such offering is a new line of indexable-insert cutters for milling aluminum from Millstar, Orion Township, Mich. Vice President Ron Field said one industry the cutting tools are targeting is moldmaking, which has seen an increase in the production of 6061 and 7075 aluminum plastic-injection molds. An aluminum mold won't last as long as a steel one, but it's easier and cheaper to machine and offers better heat conductivity for water lines, so the molded parts cool quickly and cycle times can be reduced.

The University of Louisville and UL (Underwriters Laboratories), a global safety science organization, in May announced plans for a 3D printing training facility—named the UL Additive Manufacturing Competency Center—that is set to open this fall adjacent to the university campus.

3D printing, once only in the realm of science fiction, is gaining popularity. In this military video, Staff Sergeant Scott Johnson talks about how Air Force Research Laboratory scientists at Wright-Patterson AFB are using additive manufacturing to provide the military with better equipment.

The U.S. Department of Energy (DOE) produced this video report to highlight some of the backstory behind building a 3D printed electric car in full view of everyone who attended IMTS 2014 in Chicago. The video notes that the collaboration among Local Motors, Cincinnati Inc., the Oak Ridge National Laboratory and DOE's Advanced Manufacturing Office helped spur the advancement of 3D printing technology.

In the 59th episode of our Grinding Doc Video Series, Dr. Jeffrey Badger examines the new Cubitron II grit. The research cited in this episode is described in detail in the April 2014 edition of the Welding Journal.

Automaker BMW challenged the Kennametal Inc. to develop a tool that accentuates the advantages of reaming and line boring while virtually eliminating the disadvantages. Kennametal accepted the task and developed its asymmetric line boring bar, which has two guide pads positioned so they only contact the last journal. This enables the boring bar to be quickly fed in and out of the multijournal bore without touching the workpiece. This geometry allows the bar to be fed through the raw, or unfinished, bores on an eccentric path.

A Datron high-speed CNC milling machine creates a microfluidic support plate, made of highly transparent acrylic glass, that includes microchannels.

For one shop, increasing wheel speed when cup-wheel grinding usually reduces wheel wear, but sometimes it increases wear. The shop sought the advice of Dr. Jeffrey Badger in the 56th episode of our Grinding Doc Video Series.
