An innovative kit that enables a standard CNC machining center to integrate a metal cladding process via the automatic toolchanger makes great sense—especially when one of the leading developers states his case.
At last month’s MFG Meeting in Orlando, Florida, the inaugural International Additive Manufacturing Award (IAMA) was awarded to Hybrid Technologies Ltd. limited of the United Kingdom and Plano, Texas. The winning entry for the prize is described as a hybrid kit innovation that can be integrated into any CNC machine to allow for metal deposition (via laser cladding), finishing and inspection of parts on a single machine. The hybrid methodology integrates directed energy deposition into a multi-axis CNC machine, using a toolchanger to change between processes.
“Hybrid technology is exciting because it offers a new way to adopt additive manufacturing—as an upgrade to a CNC machine tool. Adding tool-changeable deposition heads to an existing CNC machine enables 3D printing of metal, without the need to buy a separate machine,” said Dr. Jason Jones, Co-Founder and CEO of Hybrid Manufacturing Technologies. “This significantly reduces costs and provides an intuitive adoption path for CNC operators. The combination of additive with machining offers new capabilities, including in-process finishing, that cannot be delivered by either technology independently.”
Speaking at the reception during which the award was presented, Dr. Jones explained the process and describe the long journey he and his co-developers trod to make this innovation practical and effective. His remarks are clear and compelling—you can find a video of the presentation ceremony and listen to what Dr. Jones shared that evening here. Of particular value to any company interested in the experience of innovation is the advice he gives starting at 28 minutes in the video. He concludes that creativity and imagination are more important than amassed technical knowledge when forging innovation. You can also read a report about this technology here.
The IAMA is the result of a partnership between AMT—The Association For Manufacturing Technology and VDW—Verein Deutscher Werkzeugmaschinenfabriken (German Machine Tool Builders’ Association). AMT and VDW, with media support from Gardner Business Media and VDI Nachrichten and sponsored by the European Machine Tool Association CECIMO, announced the annual IAMA at IMTS 2014.
Proficient use of 3D design software from Autodesk distinguishes ITAMCO as a gear manufacturer.
Once a year, members from the Autodesk Manufacturing Community choose among the past year's monthly “Inventing the Future” honorees to select an Autodesk Inventor of the Year. The 2014 winner was recently announced and it is ITAMCO, a custom gear manufacturer based in Plymouth, Indiana.
ITAMCO delivers precision-machined components to original equipment manufacturers in a wide range of industries, including oil and gas and renewable energy; mining and construction; aerospace; and defense. Autodesk Inventor 3D design software, as part of Autodesk Product Design Suite and Autodesk Factory Design Suite, are among the tools ITAMCO leverages to serve its customers more effectively.
It's great to see a precision machining company receive this honor because it highlights the strength of this industry and the importance of the advanced metalworking technology in place there. Although precision gear manufacturing may not have much glamour among the general public, ITAMCO’s products have been used in a number of high-profile applications. NASA has chosen the company’s gears for the mechanical arm that built the international space station. The Department of Defense has used ITAMCO’s gears on its land-based satellite systems.
More recently, the company designed, manufactured and assembled a new gearbox for construction vehicles in record time by using Inventor and Autodesk Inventor HSM Pro. The software enabled ITAMCO to verify the assembly virtually for any interference issues prior to manufacturing and to utilize the advanced computer-aided manufacturing (CAM) capabilities within Inventor HSM Pro for machining the components.
It is also worth noting that ITAMCO’s operations have been enhanced by Factory Design Suite, which enables users to optimize a factory layout in a digital environment before it is completed. The company uses this software to lay out new machining cells and determine the placement of equipment to make sure the plant meets industry standards of organization and efficiency across the factory floor.
Watch this video for a demo of the hand scraping process, and find a link below to a white paper on the topic.
Hand scraping of mating surfaces on a machine tool enables the surfaces to be flatter, more accurately aligned, longer wearing and freer to glide across one another. No automated or mechanical operation can match these benefits. Machine builder Okuma has issued a white paper detailing the benefits of hand scraping, at technique it applies to all of its machines.
The company contends that hand scraping maintains high levels of CNC machining accuracy and reduces wear and tear, resulting in a long, stable and productive life for the machine. This manual process ensures that tight tolerances are consistently maintained and that precision CNC machining performance is sustained for years, therefore yielding the lowest cost-per-part, the company says.
In a nutshell, the hand-scraping difference accounts for four main benefits.
Accuracy - Scraping is done to align components within millionths of an inch, allowing for consistently-held, tight tolerances.
Flatness - Contact points prevent rocking, add balance when tightening, and allow for true flatness in parts.
Oil Pockets - Oil on the surface allows gliding motion.
Appearance - The finishing touch of scraping is aesthetic. Parts are “design scraped” to achieve an attractive textured finish.

NPE2015: the International Plastics Showcase happens March 23-27, 2015, in Orlando. Be sure to check out the technical presentations sponsored by Plastics Technology at the magazine’s Knowledge Network at Booth 2602 in the West Hall.
Many of the topics are hard-core stuff for people in the plastics industry, but others appeal to the broader interest of managers in manufacturing. These include developing a skilled workforce, additive manufacturing, moldmaking and reshoring. For the complete line-up, click here.
A visit there is also an opportunity to get complementary drink tickets, a cool T-shirt and chances to win big prizes. Registering in advance is encouraged and it’s easy. Get the details here.
Attendees at the recent MFG Meeting in Orlando had an opportunity to immerse themselves in the most important aspects of innovation as force for revitalizing the manufacturing industry.
Here are a few of the insights offered by the speakers and panelists at this event.
George Blankenship, former executive of Tesla Motors, Apple Computers and Gap Inc., make the point that innovative products succeed only if potential buyers and customers are engaged in a way that connects their core interests and values with the core features and benefits that differentiate a new product.
Talking about the Internet of Things, Rob Gremley, executive VP, Internet of Things and Service Lifecycle Management at PTC, emphasized that connected devices (which interact with everyone and everything across a global network) impose new models for how manufacturers create, operate and service them. Service (how these products sustain and renew their value to users) will require the boldest new thinking, he says.
Innovation, the drive to invent the new (new products, new methods, new ideas, new customer experiences) can be a powerful force. It saved LEGO, the global company known for its interlocking toy "bricks"). However, as David Robertson, Wharton School of Business, demonstrated, this force must be pointed toward a clear goal and led by managers guided by a clear vision.
The icon for innovation in manufacturing these days is 3D printing. A panel of experts put this development into perspective. Its power to complement and enhance conventional machining methods represents its greatest impact on manufacturing, rather than the likelihood that it will displace subtractive machining on a wholesale basis. Everyone is still learning what additive can and cannot do.
At the event, Hybrid Technologies Ltd. received the inaugural International Additive Manufacturing Award. Dr. Jason Jones, co-founder and CEO of Hybrid Technologies, accepted the award on the company’s behalf. In his comments, he related his experiences in the years-long effort to develop a practical method to combine laser metal cladding with CNC machining on the same platform. He said that the success of his company rested on bold new thinking for sure, but that persistence, patience, good luck and the ability to turn adversity into opportunity were equally important. Creativity, not knowledge, will distinguish the true innovators in this era, he said.
John B. Rogers Jr., cofounder and CEO of Local Motors (the company's Strati is touted as the world's first 3D printed car) said that manufacturing will look more personal—customers will have direct input on the making of the products they intend to buy. The real drags on innovation are not technical challenges, he said, but rather entrenched bureaucracies, closed-minded regulators and old-guard manufacturers protecting what they consider their turf.
Finally, some attendees took the opportunity to be immersed in innovation quite literally. As a novel fundraiser, a number of members of the Precision Metalforming Association, jumped into the hotel’s pool in their formal wear following the gala dinner on the list night of the event. They, and their wet tuxedos, were raising funds for the association’s PAC efforts.
Hosted by AMT—The Association for Manufacturing Technology, National Tooling & Manufacturing Association and Precision Metalforming Association, The MFG Meeting brings together the complete chain of manufacturing to discuss the current and future state of the manufacturing industry.
