When it comes to composites manufacturing, Siemens is seen as a leader with the SINUMERIK 840D sl flagship CNC. Different requirements are placed on the CNC for the building processes of tape laying and fiber placement, compared with cutting applications. To coordinate cutting control and motion control in the best possible way for fiber placement, the Sinumerik 840D sl offers synchronizing functions controlled according to actual positions, which synchronize the switch actions of the user or parts program with the motion control and position control. As a result, all the cuts sit precisely in their target positions, even at high laying speeds, which produces very clean laying edges.
The composite manufacture of aircraft parts requires an integrated, tailored process chain. The CNC functionality of the SINUMERIK 840D guarantees controlled, stable processes.
Coast Composites Inc. is a major supplier of Invar tooling, as well as resin transfer molds and mandrels used in the composite lay-up and manufacture of today’s advanced flight, critical aerospace structures. On the large, long bed CNC gantry mills used at its main facility in Irvine, California, the company is achieving an unprecedented accuracy on even the longest wing skins, as a result of the two complementary technologies that have been combined here.
The masts of winning boats in international sailing competitions fly ultralight sails of tough carbon fiber composite that are manufactured according to a special process controlled by SINUMERIK.
