Your task for this assignment is to create an overview of potential options to minimize bolt head friction suitable for cleanroom and vacuum applications. A set of promising options need to be selected and tested. A particular interest is to investigate options of rolling contacts below bolt heads. At least one version is supposed to be designed and tested as well. The tests can utilize test equipment used for testing bolt connections at ASML. For the deliverables of the thesis, you will: Investigate, describe, and structure options to minimize bolt head friction based on literature as well as brainstorming. Test plan for the test incorporating ASML tooling. Design at least one test set for a rolling friction-based variant of bolt head friction reduction. Perform the tests and evaluate and document the results.
