Learning outcomes:
After successfully completing this course, students will be familiar with the most important manufacturing processes of DIN 8580 with special reference to precision engineering. They will also be familiar with technological features such as operating principles and process parameters. Students will be able to assess the application areas of the processes and materials. They will have extended their knowledge about technical mechanics. And thus, link that knowledge with the content discussed in the course.
Students will be familiar with the most important manufacturing processes in microtechnology, their fields of application and MEMS design examples. They will understand precision and microtechnical products and their manufacturing processes.
They will refresh and develop their basic CAD and FEM knowledge required for technical drawings and component calculations. Students will be able to create technical drawings in 2D and 3D and will be able to solve simple strength of materials problems using software tools for calculation. They will be able to integrate standard parts libraries and work with fasteners such as screws, nuts, etc. Students will also be familiar with mechanical sensors.
