Kennametal Shows Benefits of MTConnect
May 22, 2013
The recent 2013 MTConnect Connecting Manufacturing Conference was instrumental in further preparing the foundation of a monumental change in how manufacturing firms can obtain, manage, and share their machine tool and tooling data. As increasing manufacturing efficiencies and productivity are primary goals of MTConnect, Kennametal has supported and was among the industry leaders presenting how these standards can work now and how shops can use them to their benefit.
As recently as 2010, manufacturing industry research stated that about four or five percent of machine tools worldwide were connected to a formal data-collection system. Each and every shop sits on a rich mine of data that it can collect for its own continued improvement, but a significant drawback is efficiently gathering the data from different makes and models of machines and tools. This has been likened to a permanently ongoing United Nations meeting with no translators.
The idea for an open shop floor standard for making all shop floor data easily accessible and workable was conceived in 2006 by the Association for Manufacturing Technology (AMT) with the first version of MTConnect released in 2008. Then, in 2009, the MTConnect Institute was established to further the development of the MTConnect standard and publish related materials. The organization includes a Board of Directors, a Technical Advisory Group (MTCTAG), a Technical Steering Committee, and various working groups to further the standard in specific technology areas.
Basically, MTConnect is an open, extensible, royalty-free standard – a communications protocol designed specifically for the shop-floor environment. By interfacing with machine tools, cutting tools, presetters or any piece of equipment or data source, software applications can be built on MTConnect standard for the efficient gathering, reporting, and use of a shop’s data.
Cutting tools can be an extremely valuable data source for shops to monitor, collect, and study, says Tom Muller, senior manager, Innovation Ventures Group, at Kennametal Inc. He chairs the MTConnect Institute’s working group on cutting tools and reported to the conference on ISO 13399 – Cutting Tool Data Representation and Exchange. Noting that MTConnect is a protocol and that ISO 13399 is an international standard, Muller demonstrated that MTConnect does not have to go into the standards development business. Since ISO 13399 already defines and standardizes such cutting tool attributes as cutting diameter, edge angle, body diameter, overall length, functional length, and functional width, among many others, MTConnect can simply adopt the ISO 13399 definitions and achieve a consistent language for exchanging data between machine tools, tool data management systems, presetters, and even CAD/CAM systems. Shops can literally monitor a customer’s project from art to part, efficiently gathering data from every step.
“The more we can drive the standardization of cutting tool data, the simpler and more efficient we can make a shop’s business,” Muller said. Imagine not only staying on top of the volumes of data a shop produces, but having machine tools “know” what the presetter and the cutters “know” through the efficient exchange of data. Hours of setup, touch-offs, and test cutting could become a thing of the disorganized past. Tribal knowledge or “how Joe does it” can make way for organized and systematized ways of manufacturing parts. MTConnect is in place, and the applications from the machine tool, tooling technology, and software leaders are coming.
