Another recent Zoller innovation is »caz« software – Computer-Aided Zoller, the virtual measuring machine. “It’s going to be a huge time-saver,” Matt asserted. “Previously we would have to create the inspection program in front of the inspection machine. Since our Star Cutter tool grinding machines come with Numroto operating software, we can export the tool model from the Numroto machine programming software as an STL file, including a 3D image, and write the inspection program from that before the tool is even ground.”

Northern Tool, a division of Star Cutter Company, Farmington Hills, MI, is well-known for designing and producing special carbide cutting tools, often for automotive powertrain production, that accomplish more than one cutting operation in a single pass.

Milling metals hardened to 52 HRC and harder with solid-carbide cutters doesn’t require a heavy-duty, high-performance machine tool when a machinist employs trochoidal milling and applies cutting tools with an appropriate substrate, coating and geometries.

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.
