Traditionally, this required the use of Computerised Numerical Control (CNC) systems to achieve such tight tolerances. However, with the increasing popularity of robotic arms in machining applications, as well as their relatively lower cost compared to CNC systems, it becomes necessary to assess the ability of robotic arms to achieve such tolerances. ...However, with the increasing popularity of robotic arms in machining applications, as well as their relatively lower cost compared to CNC systems, it becomes necessary to assess the ability of robotic arms to achieve such tolerances.

Integrated wing major assembly cell with manual assembly jigs and large CNC wing drilling machines. Twenty-three other manual work stations.

On CNC Machines, drilling holes under perfect condition is possible. For drilling holes into titanium, composite and aluminum stacked materials the specific cutting condition can be selected. ...When drilling holes in the final assembly, CNC machine tools cannot be employed due to sizes and accessibility. Power Feed Units or Automated Drill Units ADUs are very handy, flexible and depending upon the jig extremely rigid. ...In the mind-set of the fourth industrial revolution, this article presents a completely new approach in the ADU Technology, while the benefits in the capability of CNC machine tools are now available on ADUs likewise. The benefits of using individual cutting condition for every layer in composite/metal stacked material, the worldwide online-process and -data monitoring, the improved tool-management and traceability, the remote diagnostic and improved cutting tool development functions will show a variety of extremely useful and new features.

Drilling of aircraft wings to the tolerances demanded by laminar flow requires machines with the stiffness and accuracy of a CNC machine while having the flexibility and envelope of an articulated arm. This paper describes the development and evaluation of high accuracy automated processes to enable the assembly of a one-off innovative laminar flow wing concept.

GEMCOR was therefore challenged to deliver a CNC automatic fastening solution with high-speed motion control technology that would accurately and reliably perform under higher speed conditions without a foundation.

This paper presents a case of CFRP/Ti6Al4V drilling on a CNC machine where productivity must be increased. A comparison is made between the current regular process and the MITIS drilling process.

A custom CNC interface simplifies machine operations and troubleshooting. Four servo-driven, air-cooled spindles allow high rate drilling through titanium and aluminum.

Electroimpact has recently produced a high-speed fuselage panel fastening machine which utilizes an all-electric, CNC-controlled squeeze process for rivet upset and bolt insertion. The machine is designed to fasten skin panels to stringers, shear ties, and other internal fuselage components. A high riveting rate of 15 rivets per minute was achieved on the first-generation E7000 machine. This rate includes drilling, insertion, and upset of headed fuselage rivets. The rivets are inserted by a roller screw-driven upper actuator, with rivet upset performed by a lower actuator driven by a high-load-capacity ball screw. The rivet upset process can be controlled using either position- or load-based feedback. The E7000 machine incorporates a number of systems to increase panel processing speed, improve final product quality, and minimize operator intervention.

This paper will explain how massive dedicated assembly tooling can be replaced by flexible assembly methods similar to the way a CNC drilling machine replaces multiple drill templates and jigs. Flexible mate and alignment systems offer huge advantages over traditional assembly monuments including lighter weight, portable, reconfigurable to multiple airframe designs, reusable, direct interface to 3-D CAD model, and best fitting aircraft segments to one another.

Mizzou Engineering Electric Car Club contributes to national safety effort University of Missouri students gather data for hybrid and electric vehicle first responder materials. Hyundai introduces Veloster The new coupe is obviously something different from a styling standpoint, and a second rear-access door on the passenger's side just adds to that distinction.

The system is controlled by a Siemens 840Dsl CNC which handles all process functions, robot motion, and executes software technologies developed for superior positional accuracy including enhanced kinematics, automated normality correction, and anti-skid correction.

The new Exechon Parallel Kinematics technology is a standard modular "machine tool robotics system" combining the flexibility and dynamics of articular arm robots with the accuracy and stiffness of CNC machines. This new patented design gives these modules extreme mobility and, in combination with adapting technologies such as cross lasers and force sensors, it can perform accurate agile assembly over very large areas without the use of accurate large expensive heavy-duty structures.

Materials become design, design becoems function Once things you could hold in your hand, materials have become more design ideas than entities, and the designs themselves are transforming into operational activity. The next steps in flight A look at sero engine and assembly developments as commercial airframe and engine manufacturers begin the biggest battle of all-for next-generation short-haul jet aircraft sales. NextGen Today and tomorrow The FAA has reached a major milestone on the Next Generation Air Transportation System initiative to modernize America's National Airspace System. Stacking the material deck for the 787 Combinations such as composites and titanium being used in future aircraft programs can be very challenging when drilling holes during manufacturing and assembly operations.

With the addition of secondary feedback, high-order kinematic model, and a fully integrated conventional CNC control, robotic technology can now compete on a performance level with customized high precision motion platforms.

Toward greener skies Engine designers harness new technologies to embrace the eco-challenge. Going with the flow Advanced balances, pressure-sensitive paint, and wind-tunnel testing streamline aircraft aerodynamics. Orbital drilling goes mainstream for the Dreamliner Boeing and Novator worked together to overcome the obstacles of drilling holes into new material combinations being used in next-gen aircraft.

This lightweight, portable system, called Twinspin PX3, is a CNC controlled unit allowing for a continuous radial offset adjustment of the cutting tool. Based on this innovative process, it makes it possible to produce not only cylindrical holes but also conical holes or more complex shaped holes.

A woven glass fiber reinforced plastic laminate of 9 mm thickness was prepared and drilling was carried out using a CNC vertical machining centre. The thrust force and hole quality machined during drilling were compared for each drill geometry.

Industrial robots are not as stiff and rigid as conventional CNC machinery, but are far more operationally flexible and cost effective. Drilling with an industrial robot, as one component for the strive towards light-weight automation, has not yet been fully utilized in aerospace manufacturing.

This paper describes a project to retrofit five Gemcor Wing Riveting machines with new CNC/PLC controls, motors and drives, Pneumatic Systems, and upgrade Hydraulic Systems, and Processes. The emphasis here is in applying servo control technologies to the existing hydraulic actuators for the drill, transfer head and lower ram. Introduction of servo controls simplified the hydraulic systems by reducing component count. The servo control enabled automation that removed or reduced the need for operator input. These modifications were accomplished without the expense of replacing large mechanical components of the machine.
