AbstractStudents develop and build a product from A-Z! They work in teams and independently, learn to structure problems, to identify solutions, system analysis and simulations, as well as presentation and documentation techniques. They build the product with access to a machine shop and state of the art engineering tools (Matlab, Simulink, etc).
ObjectiveThe various objectives of the Focus Project are:
- Synthesizing and deepening the theoretical knowledge from the basic courses of the 1. - 4. semester
- Team organization, work in teams, increase of interpersonal skills
- Independence, initiative, independent learning of new topic contents
- Problem structuring, solution identification in indistinct problem definitions, searches of information
- System description and simulation
- Presentation methods, writing of a document
- Ability to make decisions, implementation skills
- Workshop and industrial contacts
- Learning and recess of special knowledge
- Control of most modern engineering tools (Matlab, Simulink, CAD, CAE, PDM)

AbstractDimensioning (strength calculation) of machine parts,
shaft - hub - connections, welded and brazed joints, springs, screws, roller and slide bearings, transmissions, gears, clutch and brake as well as their practical applications.
ObjectiveThe students extend in that course their knowledge on the correct application of machine parts and machine elements including dimensioning. Focus is laid on the acquisition of competency to solve technical problems and judge technical solutions and to correctly apply their knowledge according to operation conditions, functionality and strength calculations.
ContentMachine parts as shaft - hub - connections, welded and brazed joints, springs, screws, roller and slide bearings, transmissions, gears, clutch and brake are discussed. The course covers for all the machine elements their functionality, their application and limits of applicability and the dimensioning is as well as their practical applications. Exercises show the solution of practical problems. Partly practical problems are solved by the students for their own.

AbstractThe automation of production lines will be dealt as interdisciplinary topic. The course contains:
- elementary elements of automatized systems
- Chain of action: sensors, signalisation, control and closed loop control, power electronics, actors
- Conception, description, computation, layout, design and simulation
- Availability and reliability
- Modern concepts
ObjectiveThe students shall acquire knowledge for projection and realization of highly automatized production systems. They will be trained to understand, overview and supervise the whole value chain from the definition of task the specification tender, conception and projection, the detailed design and startup. They shall know and be able to evaluate the solution possibilities, and the concepts in research and development.
ContentHighly developed industrialized nations are necessarily bound to automatization of manufacturing processes for their competitiveness. Conception, realization, startup and run in of automatized production lines, "to make them alive", is one of the most exciting businesses in engineering. For the layout of automatized systems mechatronic design is of greatest importance to achieve optimal and overall supreme solutions. The course focuses on the interdisciplinary solution space, spanned by mechanical engineering, process technology, electronics and electrical engineering, information technology and more and more optics. subsystems , the information and optical subsystems. The complete processing chain, from sensing to action, sensors, signalization, control and closed loop control, power electronics and actors is discussed.

Basic elements, sensors and actors, transmitting from mechanics to electronics and vice versa, as well as control systems and interfaces and bus systems are presented. In production technology these are applied in the different automation devices and then condensed to full production lines.

Different concepts for automation, layout planning, description and simulation and the interface to and safety of humans are topics. The economic boundary conditions are taken into account and lead to concepts for availability and reliability of complex systems and to the discussion of today's research concepts for fault tolerancing systems, to autodiagnosis and self repair, cognitive systems and agent systems.
In theoretical and experimental exercises the students can gain experience, that qualify them for the conception, computation and startup of automatized systems.
