DeMaMech: EU-Japan Collaboration in Higher Education Student Exchange Program

Offer of Research Topic

Offer from	University	Delft University of Technology
	Faculty/Department/Institute	Faculty of Mechanical Engineering, Marine Technology and Material Science, Department of Precision and Microsystems Engineering
	Group Name	Precision Manufacturing and Assembly
Research Theme		Improvement of the machining performance of micro abrasive blasting by intermittent air jetting
Brief Explanation		Micro abrasive blasting is an unconventional precision manufacturing technology to machine micro structures for MEMS application by the erosive action of a particle beam. Up to know the reachable structure depth is limited to shallow cavities. To answer the industrial demand of producing structures with high aspect ratios, an improved blasting strategy is required. One possibility is to shoot abrasive particles under a high frequency onto the target.
Research Steps		1. Literature survey on abrasive blasting (one month) 2. Choosing of a suitable high- speed valve to intermit the abrasive flow (one month) 3. Implementing of the valve in an existing blasting set up (one month) 4. Running of a test set to evaluate the influence of the shoot frequency (one months) 5. Analysis of the experimental results written down in a scientific report (one month)
Period		5 months.
Necessary Background, Knowledge, Skills		Experience in planning and performing of experimental investigations. Basic knowledge on electro-pneumatic installations required.
Further Information		B. Karpuschewski, A.M. Hoogstrate, M. Achtsnick, Simulation and Improvement of the Micro Abrasive Blasting Process, Annals of the CIRP 51 1 (2004) 251-254.

European offers have to be 5 months, due to the EU requirement to Japanese students that they have to stay at two European Universities.
