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.
With thousands of fastener locations that need to be drilled and filled to complete a plane, drilling and fastening remain the largest areas of opportunity for automated robotics applications in aerospace. New developments are also making robots more attractive than ever in the aerospace and defense space—especially improved rigidity and accuracy in the robots themselves.
Automation development in the aerospace industry has quickened its pace, with the aviation and defense industries attempting to further automate manufacturing processes to meet growing OEM order backlogs and critical aerospace-defense program deadlines.
Today’s products require high finishes, burr-free edges, freedom from contamination, and often close tolerances. Electropolishing provides all of those conditions and more in a matter of seconds for many metal parts. It is a process that has been used for more than a hundred years. It is widely known and the science is widely discussed, but its ability to run job shop lots and high-precision high-volume parts in the same equipment makes it a bit unique.
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.
All fixtures are designed to hold a workpiece in position firmly and accurately during a manufacturing process.
Sales of cars and light trucks plummeted during the Great Recession and General Motors Co. and Chrysler emerged from government-back bankruptcies in 2009. Since then, total industry deliveries have surged, hitting a record 17.47 million in 2015, according to Autodata Corp.
Modernizing the smaller shop with the latest digital tools available from enterprise resource planning (ERP) software developers
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.
Burrs, sharp edges, and rough surfaces plague even the most precise metal-cutting or forming process. Deburring and finishing can often be treated as the step-child of a manufacturing process, but its importance is growing as tolerances get tighter and precision devices become the norm.
