A successful design starts with a complete set of specifications and a good concept.
But the elaboration of this often also requires a lot of attention. Is the intended stiffness achieved? Are the material stresses within the set requirements? Is there no hidden stick slip? Does the composition meet the required dimensional accuracy if all production tolerances are taken into account? What failure mechanisms are there?
These are all questions that can be answered in the design phase. I (Jaap Vink) have solid experience with these kinds of fine mechanical analyses. My years of practical experience provide a broad perspective.
I started as a developer at Canon Production Printing (then Océ) in Venlo. Within the development of a wide format scanner printer (up to A0), I worked on the scanning module and the exposure module.
After a few years I switched to ASML in Veldhoven. I worked at Development there for about 22 years. First as a designer and soon as a (senior) engineer in a group that supports designers with:
drawing up specifications for (sub) systems;
(fine) mechanical analyzes;
setting up and conducting qualification tests;
I often worked in opto-mechanical projects, but also in mechatronic projects. In later years, one of the important tasks was to carry out tolerance analyses. At ASML I helped develop the structured, methodical approach.
I also developed an Excel template for tolerance analysis. This allows any mechanical designer to set up, calculate and present his analysis in the same way. Through the tolerance analysis course, provided by Mikrocentrum, the mechanical designers at ASML are now learning to work with this Excel template.
In 2007 I continued as a self-employed person in the same field and I also used my knowledge and skills with the engineering firm Vink System Design & Analysis for other companies, such as Mapper Lithography.
Tolerance Analysis Course
Furthermore, because of my knowledge of and experience with tolerance analyzes, I have been asked by the Mikrocentrum to be a teacher for the open courses and internal courses Tolerance Analysis. Practice has shown that the course is suitable for many companies in all kinds of sectors.
