Automated Composite Manufacturing and its Long-term Possibilities

Automated composite manufacturing has been researched for several years. This article specifically addresses the question: "What are the long-term benefits for the economy and the global technology standard if manufacturing in the composite sector is automated? Composites have long been familiar materials in the development and construction of machines. They are very light and have mechanical advantages over conventional materials. Therefore, they are mostly found in industries where the lightweight construction philosophy is of higher importance. The application of products made of composite material therefore has mainly constructional backgrounds. This is because composite technology has a decisive disadvantage. Development and [...]

Automatisierte Composite Fertigung und ihre langfristigen Möglichkeiten

Die automatisierte Composite Fertigung wird bereits seit einigen Jahren erforscht. Dieser Beitrag behandelt gezielt die Frage: "Warum gibt es auf langfristige Sicht Vorteile für die Wirtschaft und den weltweiten Technologie-Standard, wenn die Fertigung im Composite Bereich automatisiert wird?" Faserverbundkunststoffe oder auch Composites sind schon seit Längerem bekannte Werkstoffe in der Entwicklung und Konstruktion von Maschinen. Sie sind sehr leicht und besitzen dennoch mechanische Vorteile zu herkömmlichen Werkstoffen. Daher sind sie meist in Branchen zu finden, in denen die Leichtbau-Philosophie von höherer Bedeutung ist. Die Anwendung von Produkten aus Faserverbundkunststoffen hat demnach hauptsächlich konstruktionstechnische Hintergründe. Denn die Faserverbundkunststofftechnik hat einen entscheidenden [...]

Easy and Flexible: Knowledge Based Engineering in Product Development

On the way to development 4.0 Enter the race with Knowledge Based Engineering You might think the industry is in an eternal race. In a race in which the time to market of a product embodies the lap time and product quality is the decisive factor in staying in the race - in competition. The company that develops, produces and launches the best product the fastest is ahead. As in motor sports, there are also innovation thrusts around product development. Digitalization is one of the most important developments and is in full swing. In this context, Knowledge Based Engineering (KBE) [...]

Modular Software Development with NuGet

What makes modular software development so special? Modular software development refers to the separation of a software project into individual, logically separated components. This modularity leads to the fact that the individually available software components can be developed separately from each other and then (re)used. As already mentioned in the blog post on unit testing , this has the great advantage that the individual modules can be tested separately. Software developers can use already finished components without (partially) redeveloping them. This blog post will discuss how software packages are created and delivered. One of the most common ways to realize [...]

More Space for Ideas - Automated Design

The Sword of Damocles of Digitalization " Digitalization " and - in the technical field - " Industry 4.0 " are omnipresent and much discussed. To some, they may already seem trite, but there are also many debated concerns about the future world of work and the preservation of one's own job. In almost all areas, a wide variety of processes can be automated today and the technical possibilities are constantly growing. The job description of an engineer is also affected by this, so that current developments can cause not only enthusiasm, but also worries and fears about the future. [...]

Lean, Agile, Innovative. Development at SWMS

Unpopular Onlooker: The Risk At some point we are all customers and none of us likes to buy a pig in a poke. The bigger the investment - for example an individual software solution - the less risk you want to take. Unfortunately, this risk seems to increase with the size of the project. This also applies to the contractor, depending on the contract. Frequently, fixed budgets for a fixed scope of delivery are agreed in this way. Although this provides clarity about sums and deadlines, what happens until the project is completed, the laughter about some project cartoons gets [...]

Automated Testing with Entity Framework 6

In software development, testing applications and troubleshooting takes up a large part of the time. If the modules of a software are clearly separated by loose coupling of dependencies, the software can be tested in isolation using Dependency Injection and Mock objects. However, if external resources are used by the software, such as USB devices or databases, automated testing becomes more difficult. So this blog post is about testing a database connection with Entity Framework 6. A simple ASP.NET MVC application Fig. 1 shows the rough software architecture of a simple ASP.NET MVC App. The app consists of several layers [...]

The CAD-CAM Process Chain - Reduce Media Breaks, Lean to Result (Part 2)

This text follows on from the previous article " The CAD-CAM Process Chain: The Status Quo ". An important prerequisite for the optimization of the CAD-CAM process chain is the avoidance of media breaks and the associated loss of information. Media breaks occur when different, unconnected, often even incompatible systems are used for different tasks in the product development process. This does not mean that only systems "from one casting" are suitable for modern production. Coordinated systems and, above all, the underlying processes also offer many possibilities. First we consider the problem of information loss and its origin. [...]

Konzeption von BDE und MES in der Variantenfertigung

Unser Kunde ist ein mittelständisches Unternehmen mit eigener Fertigung. In einer Fertigung mit hoher Fertigungstiefe stellt unser Kunde Katalysatoren her, die unter anderem in Biogasanlagen eingesetzt werden. Herausforderung Aufgrund von Unternehmenswachstum und stetig steigenden Auftragszahlen wird momentan die Fertigungsfläche erweitert. In diesem Zuge hat sich das Unternehmen mit der Fragestellung beschäftigt, wie die Fertigungsprozesse besser als bisher durch IT-Systeme unterstützt und optimiert werden können. Vorgehen Im Rahmen einer Prozessanalyse, angelehnt an die Methode des Werkstromdesigns, wurden Pain Points in der Produktion identifiziert. Die Fertigungsaufträge gelangen momentan über Papierzettel an die unterschiedlichen Arbeitsstationen. Bei der aktuellen Größe ist dies erstmal kein [...]
