Resistance Rivet and Insert Welding - A Flexible Manufacturing Technique for the Aluminum/FRPs-Steel Multi-Material Body Structures2024-01-207104/09/2024
Automotive body structures are being increasingly made in multi-material system consisting of steel, aluminum (Al) and fiber-reinforced plastics (FRP). Therefore, many joining techniques such as self-piercing riveting (SPR) and adhesive bonding have been developed. On the other hand, OEMs want to minimize the number of joining techniques to reduce the manufacturing complexity. Amount all joining methods, resistance spot welding (RSW) is the most advanced and cost-effective one for body-in-white. However, RSW cannot be applied for joining dissimilar materials. Therefore, a novel Rivet Resistance Spot Welding method (RRSW) was developed in which Al or FRP components can be directly welded to steel structures with existing welding systems. RRSW uses rivet-like double T-shaped steel elements as a welding adapter which are formed or integrated into Al or FRP components during their forming process. After that, they are welded to the steel components by RSW. This paper shows at first the

Optimizing Concurrent Scheduling of Machines and Tools in a Flexible Manufacturing System with Alternating Machines Using the Flower Pollination Algorithm2023-28-014111/10/2023
This paper examines the concurrent scheduling of machines and tools with machines in a multi-machine flexible manufacturing system (FMS) with the aim of minimizing the makespan in automobile manufacturing industry. Due to the high cost of tools in FMS, each type of tool has only one duplicate in circulation. To reduce the cost of duplicating tools on each machine, a central tool magazine (CTM) is used to store and share tools among several machines. The main challenge in this scenario is to allocate machines from alternate machines and tools to job operations in a way that minimizes the make span. To address this problem, the article proposes a mixed nonlinear integer programming formulation and a Flower Pollination Algorithm (FPA). The results show that the FPA outperforms existing algorithms and using alternate machines for operations can reduce the make span. Therefore, this paper suggests that the FPA-based approach can be effectively utilized in real-world FMS applications

BMW takes multi-modal route to manufacturing23AUTP03_0803/01/2023
BMW's Munich factory remains the fertile root of a century of manufacturing, including its first R32 motorcycle in 1923. At the Munich plant - flanked by the engine-shaped “four-cylinder” headquarters tower and futuristic BMW Welt museum and customer-delivery center - BMW recently showed media its reimagined “iFactory.” This lean, green and digitized environment can build ICE, hybrid, electric or even hydrogen fuel-cell models on a single assembly line. That master plan includes a car and battery factory in Debrecen, Hungary, that BMW claims will be the industry's first CO2-emissions-free plant in 2025, fed entirely by photovoltaic or other renewable electricity

Implementation of Reconfigurable Manufacturing Systems in the Manufacturing of Turbo Charger Turbine Housing2019-28-013510/11/2019
Today manufacturing industries have become more competitive and to survive, industries should be capable of accommodating the sudden market change. The conventional manufacturing systems like Dedicated Manufacturing Lines (DMLs) can produce high volume of product but difficult to cater to varying product types. On the other hand, Flexible Manufacturing System (FMS) is capable of handling product variety but not suited for mass production, The Reconfigurable Manufacturing System (RMS) gives the advantage of both the system, as it has the capability to adjust to both high volume requirement and product variety, and it able to upgrade to new process technology with minimal effort. In this work the reconfiguration is carried out in machine and system level. At machine level, a new inspection machine is proposed which can be used for multiple products with minimal adjustments and a special drilling and bore tool is suggested to reduce the cycle time and ramp up time when product changes.

CASTING AROUND FOR lightweight solutions19AUTP10_0210/01/2019
The United Kingdom's Grainger & Worrall is introducing and perfecting “new and imaginative” casting-technologies. “Get more [efficiency] from less [weight, time, cost],” is a mantra that will be chanted sotto voce by many an automotive designer and engineer facing the latest list of a new vehicle's “requirements.” Many propulsion solutions are possible, some of them evolutionary, that bring new opportunities for application within a rapidly-changing industry. But not all are focused on the design of pure EVs. Experts forecast that the internal combustion engine (ICE) will remain a mainstay of production vehicles-the majority used in hybrid configurations-for many years to come

Potentials of Human-Robot-Cooperation in Aircraft Assembly Systems / New possible applications of a human-robot-cooperation in aircraft production by the example of shell structure assembly2015-01-250709/15/2015
The automation of assembly processes in aircraft production is, due to technological and organizational boundary conditions, very difficult and is subject to technological challenges and economical risks. The technological challenges are especially the large product dimensions as well as the high amount of variants. At the same time, aircrafts are produced in low quantities with inflexible and expensive fixtures. As part of the research projects TRSE (semi-automated robot welding for single item production) and 4by3 (Modularity, Safety, Usability, Efficiency by Human-Robot-Collaboration) at ZeMA, the goal is to develop new process technologies, planning tools and adequate equipment in order to enable efficient and customized automation for various production processes.

Finding the right balance11AEID0405_0404/05/2011
Engineers identify key technology trends such as the necessity for lighter, smaller engines and vehicles-and stress that managing trade-offs is an especially tough challenge. When asked to select the two most important environmental/sustainability issues in their development work, SAE-member engineers responding to a survey recently conducted for DuPont and Automotive Engineering International indicated the top three to be hybrid and electric vehicles (EVs), technologies that boost performance of smaller engines, and lightweighting (for CAFE), with 47%, 47%, and 31%, respectively. Remarkably, when this DuPont/AEI survey was last conducted in 2008, batteries and EV technology (the word “hybrid” was excluded) were considered the most important sustainability issue in only 3% of respondents' work, illustrating the industry's keen focus on vehicle electrification over the past three years. Also in 2008, the use of bio-based fuel and alternative-fuel issues ranked second with 44%; this year

Building blocksAUTOFEB09_0602/01/2009
Engineering a good engine is half the battle; getting it through the assembly process without introducing flaws is the final victory. With gasoline prices as volatile as they've ever been, it is difficult for automakers to judge future demand for the various models in their product range. An appropriate amount of manufacturing flexibility, not just for vehicle models but also for engine models, can go a long way in these uncertain times. That is particularly so as automakers the world over, especially those in the U.S., are trying to downsize their engines. A gradual move in the U.S. away from eight-cylinders to six-cylinders and four-cylinders is already under way. “The gas spike this summer drove more of that thinking,” said John Lucci, a partner in the Global Automotive Practice of Oliver Wyman Consulting. “Now, as gas prices have gone to the lowest in years, all bets are off regarding the speed at which these changes will continue

Finding flexibilityAUTONOV08_0311/01/2008
Although automation is important to achieving flexibility, manufacturers cannot neglect product design, manufacturing processes, and personnel. As the current market volatility shows, automakers might need flexible factories now more than ever. Besides supporting agility in the marketplace, flexible factories maximize capacity utilization, if used correctly. A factory that costs less, that is loaded up to 100% capacity with different models, and that switches over quickly to respond to a fickle market is the ideal automotive factory of today-for vehicles or parts, OEMs or suppliers. “I have been studying flexible automotive manufacturing for over 15 years,” said Jay Baron, President of the Center for Automotive Research (CAR.) “A number of myths persist. For instance, there is the myth that a flexible plant costs more. Well, that was true 15 years ago, but today there is a lot of flexible technology that costs less, not more

Simulation at the Heart of an Automated Aerospace Manufacturing Process2006-01-315009/12/2006
The traditional use of simulation software in aerospace manufacturing applications has been as a pre-production tool for the validation of tool paths and the generation of robot programs. Once the process has been proven via simulation, the data is then transferred to the machine or robot and the production process executed. This is a linear approach in which the virtual and real systems are operated independently and in a serial manner. The current capabilities of offline programming (OLP) and simulation systems when combined with appropriate hardware in a flexible manufacturing environment now allow them to be used right at the heart of a manufacturing process, as an integral part of the manufacturing route. In a flexible manufacturing cell such as that developed at the University of Nottingham for the automated assembly and riveting of large aerostructures, a key driver is the need to reduce or eliminate complex and costly jigs and fixtures for part positioning.

Sharing the wealthAUTOMAY05_0405/01/2005
A versatile vehicle architecture can deliver multiple variants from a single platform, reducing development costs and time-to-market. Over the past few years, automobile manufacturers in the U.S. have been focusing on developing processes and tools to enable production of a range of vehicles that are distinctive to the customer but share core technology underneath. The intense competition in the marketplace has driven companies to compete in new market segments, and the challenge is to keep volumes high enough to pay for the capital investment required to constantly deliver new and exciting products. Flexible manufacturing processes contribute significantly to this objective, and product development now routinely addresses multiple variants at the concept design stage.

Bodybuilding and chassis integrationAUTOJUN04_0606/01/2004
Automakers are becoming more open to material mixing and matching for bodies, and they see great potential in further electronic chassis systems integration. Aluminum has transformed chassis design over the past 20 years. Its contribution to weight reduction of suspension components to significantly enhance vehicle dynamic performance is now the norm, and there is every sign that aluminum's automotive influence will continue to grow. However, not every manufacturer agrees on what that growth path should be. Both Audi and Jaguar have elected to build all-aluminum-bodied cars, while BMW has taken a median course, using aluminum for chassis components but joining aluminum (front end) and steel (passenger compartment) for the body shell where it feels it is appropriate, particularly to obtain the 50:50 weight balance that it regards as ideal to help achieve the optimum handling balance for its cars

Tuning of Multi-layered Acoustic Systems2003-01-143705/05/2003
The ability to utilize existing infrastructure i.e. tools, equipment and machinery to generate a unique acoustic product offering with minimal changes is important. This is because no generic acoustic solution ( material or composite ) exists for different vehicle configurations. Also, recent developments in predictive acoustic engineering and enhanced CAE capabilities as applied to development of optimal flat sample criteria for in-vehicle transmission loss and absorption performance allow for reverse engineering of the noise control systems. This reverse engineering coupled with a flexible manufacturing system will allow customization or tuning for any given program. Cost effective acoustic systems that can provide optimal insertion loss/absorption ratios utilizing a common manufacturing process will be the enabler to sustain competitive advantage.

Development of Optimal Production Control Strategies Using Experiment Planning - A Study Case in the Earthmoving Industry98151204/08/1998
Control strategies - the long term rules used in production planing and control - for highly integrated and flexible manufacturing systems in most cases are specialized in specific and usually constant production programs. Therefore, changes in the production program require adaptations in those single or combined control strategies. To keep the system optimal, there is a need for more than just analytical mathematical methods, whose limits are quickly crossed because of their complex correlations. An effective device for the development of optimal control strategies connected with an advantageous system structure is the focused Experiment Planning. It combines static analysis and calculations with dynamic simulations in order to develop alternatives for improvement of control strategies and the system structure in a repetitive process. The use of the Experiment Planning enables an efficient adaptation of control strategies and the system structure to a changed production program, such
