The Institute of Machine Tools and Manufacturing, at ETH http://www.iwf.mavt.ethz.ch/index_EN is seeking a Ph.D. researcher in the area of machine design, precision engineering and control.
Problem statement
In the sub-micron range motion systems have to satisfy strong specifications in a plurality of aspects. Accuracy requirements in the nanometre-level, dynamic specifications in tens of g, but also economic target values have thoroughly to be met at the same time. For this reason, the development of sub-micron motion systems constantly expands to the borders of feasibility imposed by physical laws, this in order to allow full exploitation of the principles of precision engineering. For this task dedicated simulation represents an enabling mean for the development of future generations of these dedicated mechanisms. The modeling of corresponding systems requires the fusion of mechanical, thermal, electric, metrology and control disciplines in order do obtain the properties of the systems under investigation.
Scientific objectives
The scientific focus of the thesis can be outlined as:
"Advanced modeling of static and dynamic behaviors in complex machines"
The work will cover precision engineering in the nanometer range for high acceleration and high accuracy. This involves:
1) Elaboration of an adequate actuation system
2) Selection of an applicable metrology and control strategy
3) Realization of a prototype and assessment of properties for validation
4) Deduction of a procedure to transform system requirements of sub-micron motion systems into the design of these systems
Organisation of the Thesis
The selected Ph.D. student will work at ETH, under an employment contract with the company ETEL, which he will visit regularly during the three years of thesis.
Content of the thesis: System analysis, modeling, actuation, metrology, design, simulation
Requirements: Interest to work in a cutting edge, industry-related topic
Applicants should send a cover letter briefly describing their background and career plans, a CV, and the names and contact
information for at least three references. The position is open immediately. These documents should be submitted as pdf attachments to Dr. Sascha Weikert: weikert@inspire.ethz.ch
