The paper formulates basic requirements to the tool-holder/spindle interface for different machining operations. A comparison of some alternative and commercially available designs is presented. Two advanced interface designs which are fully compatible with existing 7/24 taper spindles and toolholders while providing enhanced accuracy in axial and radial directions, higher stiffness, insensitivity to high rpm, and reliability at high rpm are described and results of their evaluation are presented.

Robotic gripper technology has been integrated into CNC riveting machines. Handling fasteners efficiently is critical in automated wing panel riveting.

They were installed on two production CNC riveters to provide improved edge tracing of longerons and drill/countersink control. The optical tracer uses video techniques to maintain a constant edge distance for fastener locations.

Marotta turns things around The valve-making company used to have trouble getting product out the door on time, but it has improved its turnaround dramatically via lean thinking. A view from the factory Manufacturing techniques and materials used in other industries may be debuting at aerospace factories near you. Reverse engineering Using digital processes accelerates design and increases manufacturing quality. Fine-tuning aerodynamics The aerospace industry relies on massive amounts of computing power to continually simulate, test, and optimize vehicles for reliability and accuracy.

Toward smarter manufacturing and materials At the U.K.'s new Advanced Manufacturing Research Center, engineers and innovators have at their disposal some of the world's most advanced design and manufacturing assets for precision engineering. More electric, integrated fuel systems Engine system reliability can be improved by advanced electric architectures, while the reduction of hydraulic components, fuel tubes, and fittings can enhance the maintainability of the engine and minimize pilot workload.
