Automation: The Future of Medical Manufacturing

  • Magazine Article
  • TBMG-35367
Published 2019-10-01 by Tech Briefs Media Group in United States

Manufacturers in the medical industry face unique challenges in terms of product mix, throughput requirements, quality standards, and regulatory guidelines. Whether a company is developing imaging equipment, orthopedic implants, or diagnostics, the manufacturing process must be absolutely error free while delivering high throughput. Device companies are looking more and more to factory automation to ensure that they are addressing these disparate requirements.

Metal Stamping: Converting Parts for Cost Savings

  • Magazine Article
  • TBMG-35372
Published 2019-10-01 by Tech Briefs Media Group in United States

In today’s world of medical device manufacturing, cost pressures are very real. At the same time, cost savings can be just as real, especially when companies examine their manufacturing processes for greater efficiencies. One area that is gaining particular attention is metal stamping of previously machined, metal injection-molded, or laser-cut parts.

Collaboration in a Hybrid Team of Human and Robot for Improving Working Conditions in an Aircraft Riveting Process

SAE International Journal of Advances and Current Practices in Mobility

ZeMA gGmbH-Rainer Mueller, Matthias Vette-Steinkamp, Ali Kanso, Tobias Masiak
  • Journal Article
  • 2019-01-1372
Published 2019-03-19 by SAE International in United States
Aircraft production is facing various technical challenges, such as large product dimensions, complex joining processes, and organization of assembly tasks. Overcoming such challenges, as well as maintaining low tolerances and small batch sizes, is often difficult to achieve whilst retaining economic viability.ZeMA believes that a semi-automated approach is the most effective way to optimize aircraft section assembly. This can be achieved with a semi-automated riveting process for solid rivets, using Human-Robot-Collaboration in combination with an intuitive Human-Machine-Interaction operating concept.In the assembly of aircraft structures - in this scenario the aircraft aft section - the pressure bulk head is mounted to the section barrel. Two operators work collaboratively in uncomfortable, non-ergonomic positions, yet of course have to maintain exacting quality standards. In order to improve this process, a dynamic task sharing strategy between human and robot according to their respective skills, with due consideration given to ergonomic factors is proposed. The ideal solution involves placing a robot inside the section barrel. The robot’s workspace is expanded by mounting it on top of a lifting unit so…
