AS9145: Requirements for Advanced Product Quality Planning and Production Part Approval

  • Professional Development
  • C1917
Published 2018-12-14

Production and continual improvement of safe and reliable products is key in the aviation, space and defense industries. Customer and regulatory requirements must not only be met, but they are typically expected to exceeded requirements. Due to globalization, the supply chain of this industry has been expanded to countries which were not part of it in the past and has complicated the achievement of requirements compliance and customer satisfaction. The IAQG has established and deployed the AS9145 Standard, as a step to help achieve these objectives. The hope is to also reduce costs worldwide by enforcing these activities through the regional representatives: Americas (AAQG), Europe (EAQG) and Asia/Pacific (APAQG).

Managing Functional Safety (ISO26262) in Projects

KVA-Agish George, Jody Nelson
Published 2017-03-28 by SAE International in United States
The ISO 26262 standard for functional safety was first released in 2011 and has been widely incorporated by most OEMs and Tier1 suppliers. The design and conformance of the product to functional safety standards is strongly intertwined with the product development cycle and needs to be carefully managed. The consideration for functional safety needs to begin right from the product’s concept phase through engineering and production and finally decommissioning. The application of the standard in a project can bring significant challenges especially to managers who are relatively new to the standard. This paper provides some guidelines on the key tasks involved in managing ISO26262 in projects and some ways to approach them. The paper is expected to help managers manage ISO26262 compliant projects. The paper also tries to come up with a metric that can be used for resource estimation for implementing ISO26262 in projects.

Grinding Machines Offer Unique Capabilities for the Medical Industry

  • Magazine Article
  • TBMG-25590
Published 2016-10-01 by Tech Briefs Media Group in United States

The recent emergence of specially designed five-axis grinding machines can now meet the highest expectations of accuracy and machine dynamics within the special demands of the medical industry, particularly the orthopedic segment. A short setup time and high flexibility in equipment and software changeover are among these new machines’ many advantages for end users. To achieve this performance level, many companies have relied on their experience in building various machine tools, which include grinding machines and multispindle lathes.

 

An Attempt for an Industry 4.0 Inspired Cloud-Supported Approach for Predictive Maintenance on the Example of Refill Friction Stir Spot Welding (RFSSW)

Helmut Schmidt University-Henry Hameister
Published 2016-09-27 by SAE International in United States
This paper presents an approach to how existing production systems can benefit from Industry 4.0 driven concepts. This attempt is based on a communication gateway and a cloud-based system, that hosts all algorithms and models to calculate a prediction of the tool wear. As an example we will show the Refill Friction Stir Spot Welding (RFSSW), a solid state joining technique, which is examined at the Institute of Production Engineering (LaFT) of the Helmut-Schmidt-University, University of the Federal Armed Forces Hamburg, for years.RFSSW is a sub-section of friction welding, where a rotating tool that consists out of three parts is used to heat up material to a dough-like state. Since Refill Friction Stir Spot Welding produces a selective dot-shaped connection of overlapping materials, the production requirements are similar to riveting or resistance spot welding. In contrast to other bonding techniques, Refill Friction Stir Spot Welding can be integrated within the production process without major interferences or changes. At the LaFT we build a prototype from which we collected a big amount of data which we…

Published 2016-09-01 by Tech Briefs Media Group in United States

As medical devices become smaller, the need for precision microminiature components increases. This provides several challenges for the medical device manufacturer as they seek cost-effective parts meeting the exacting quality specifications that play a critical role in the overall performance of the medical device.

 

Design and Development of a Novel Re-Configurable Fixturing System

University of Moratuwa-N.D. Jayaweera, L.U. Subasinghe, H.G.A.R. Gajanayaka
Published 2015-09-15 by SAE International in United States
Modern aerospace industry is continuously seeking new technologies due to potential increase in demand for new aircrafts which are to be produced on a single production line while reducing model changeover time and improving quality of the assembly process. In mass volume production, this can be achieved by fixing a large number of similar components using special-purpose jigs and fixtures. This type of jigs and fixtures can be largely found in Aerospace industry. In low volume production, improvement of re-configurable fixturing systems becomes a favourable way to reduce the cost of production per unit. A re-configurable fixturing system consists of standard components that can be used to satisfy different fixturing requirements. These fixtures are reusable and this enhances their flexibility and reduces the time and cost of development. It also offers the benefit of eliminating the need for dedicated tooling, dedicated fixturing, associated storage and floor space. Re-configurable fixturing also provide rapid response to engineering and production changes, system expandability, and considerable reduction in setup time. In this research a novel concept of re-configurable fixturing…

Published 2015-06-15 by SAE International in United States
An important trend among vehicle NVH engineers is the production of attractive engine acceleration sound quality for the enhancement of a vehicle's image and performance. In addition, customers have increasing interest and enjoyment in customizing their cars to reflect their personal taste and preferences.The PESS (Personalized Engine Sound System) has been developed for making a unique and individually customizable vehicle concept. The system allows the customers an opportunity to create a variety of engine sounds in a single vehicle using active sound design technology.In this system, three different engine sound concepts are pre-defined, Dynamic, Sporty, and Extreme. Each of the engine sounds can then be adjusted with parameters that determine the timbre, such as main order, rumble, and high order. In addition, the pedal position during acceleration has also been used as a parameter to further personalize the experience. An application in the Audio-Video Navigation system (AVN) has been implemented that allows users to easily customize these functions.It is expected that the system will provide a new auditory experience as well as an enhancement to…
