Overall, there are two overriding customer needs: reducing cycle time and machine downtime. They want higher feed rates and depth of cut for greater metal removal.
Demand for machining titanium for aerospace applications won’t abate any time soon. It is driving OEMs and the supply chain in the commercial airplane market to find ways to dramatically increase machining output. Whatever date you pick from now until 2030, there’s a sufficient backlog of commercial airliners for both structural and jet engine applications to keep spindles humming around the clock cutting titanium.
Simulation tools are making it much easier for manufacturers to optimize their processes, visualizing the entire path of production from NC metalcutting simulations through 3D design and factory-floor imaging.
Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.
As additive manufacturing emerges from a long infancy, the industry is grappling with a key challenge: A file format and design tools from the 20th century are being asked to do 21st century jobs.
When you walk into the Redeye On Demand facility in Eden Prairie, MN, you enter into one version of the factory of the future. There you will see a bank of 100 high-end Fortus fused-deposition modeling (FDM) machines from Stratasys that provide the capacity to build real, functional parts with production-grade thermoplastics directly from CAD data.
Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
For Dale Mickelson, Yasda product manager at Methods Machine Tools Inc. (Sudbury, MA) and author of several books on hard milling, tackling heat-resistant superalloys (HRSAs) requires the perfect combination of machine, workholding, tooling, tool paths and coolant.
As additive manufacturing (AM) moves from prototypes to mass production, manufacturers are setting their sights on the holy grails—the products and processes that will be game-changers. Many game-changers are already in play.
Constant refinement of medical machining from tooling design to finished product requires not only the ability to handle a broad range of plastic and metal materials but also to achieve predictable results—particularly in the face of strict regulations.
