Meeting the needs of the evolving digital manufacturing initiative, Open Mind Technologies (Needham, MA) has recently partnered with Heidenhain TNC controls (Schaumburg, IL) to provide exclusive first use of their new NC code-based machining simulation solution hyperMILL Virtual Machining.

If NASA’s Journey to Mars project succeeds, the astronauts who make the 140 million-mile (225 million-km) trip to the Red Planet in the 2030s will need someplace to stay. The space agency is looking at 3D printing, using on-site materials, to manufacture humanity’s first deep space home.

New materials for additive manufacturing are used for a diverse range of applications, including 3D paints for making human tissue-like cells; a hardenable stainless steel powder for surgical instruments; and a sustainable composite reinforced with bamboo fibers that resembles wood when printed.

If you’re trying to optimize metalcutting speeds, especially in difficult-to-machine materials, “Heat transfer is the name of the game.” That’s the summary offered up by Ranajit Ghosh, manager of applications R&D and growth for Air Products (Allentown, PA). “Most heat from a machining operation exits through the chip, but some transfers to the cutting tool, toolholder, machine spindle and workpiece. Heat buildup in the cutting tool causes thermal softening of the edge, which is why we often have to employ coolant.”

HP Inc. (Palo Alto, CA) said today it’s introducing an industrial-sized 3D printer and expanding its offering of materials for additive manufacturing.

The road to manufacturing success today runs through the mountain of data that tools are generating in metalcutting applications, and most importantly communicating and reacting to in real time on the shop floor.

While EDMs offer the benefits of holding tight tolerances, working on nearly any metal, and being well suited for delicate or fragile parts, knowledgeable operators for the machines are increasingly hard to find and robots can’t always fill the gap. Automated processes in the machines, newer designs and features of Industry 4.0 are helping to solve the problem.

In aerospace manufacturing, where high strength, light weight, and corrosion resistance are key material traits, those same qualities make materials hard to machine. In response, Greenleaf offers a new ceramic for cutting tools, Sandvik Coromant’s advice for machining new, complex titaniums is to go slow, and RobbJack has designed a drill specifically for CFRP composites.

Cars of the future always will be more intelligent and they also will be able to drive autonomously.

When Desktop Metal introduced its “office-friendly” Studio metal prototype printer earlier this year, the company renewed attention on the issue of safer materials for binder jetting, an additive manufacturing method.
