ASML
Graduation assignment: Design special tooling to optimize the placement of an XY motor
Introduction
This is a graduation assignment for a bachelor student at a University of applied sciences in Mechanical engineering, who is not afraid of a challenge and who is interested to be responsible for the design process for special tooling to ensure succesfull controlled placement of an XY motor.
Job Mission
You will become part of the waferstage team, responsible for enhancing the wafer stage in our newest EUV lithography machines, one of the most advanced machines ASML currently makes. The team consists of a combination of young ambitioned and experienced senior engineers, who all are willing to share information and knowledge.
A current challenge for our engineers is place an XY motor successfully in one of our machine parts, the ‘mirrorblock’. Due to the combination of large weight and tight fitting tolerances this is found to be difficult. Attempts are made to improve the placement without the use of special tooling, however the results were not satisfactory.
To ensure successful controlled placement, special tooling is needed. This is where we need your help! In this assignment you will be responsible for the entire design process of such tooling, starting from scratch.
Before thinking in solutions; it is important to first define a solid product specification. Using this product specification, you will have to come up with concept designs for the tooling. Comparing the concepts on risks and performance will lead to one final design, completed using drawings and documentations.
During your assignment you can expect the following work activities:
- Strong collaboration with colleagues responsible for the placement of the XY motor;
- Defining product specification together with all stakeholders;
- Brainstorming, and defining concept designs;
- Making a tradeoff between the concepts;
- Making a detailed design;
- Writing technical documentation;
- Doing tolerance analyses.
Of course you will receive the right mentoring to complete these tasks to the best of your ability.
