This thesis focuses on producing hybrid freeform surfaces using an advanced diamond-turning process, understanding the generation of surface accuracies (form errors) and how the choice of cutting strategies affects these, as well as simplifying the complications of generating cutting paths for such freeform surfaces. The breakthroughs behind this thesis are the development of novel, multiple-axis, diamond turning techniques to overcome the limitations of conventional diamond turning processes, an analytical model to optimize the generation of ultraprecise freeform surfaces, and an add-on tool…mehr

Produktbeschreibung
This thesis focuses on producing hybrid freeform surfaces using an advanced diamond-turning process, understanding the generation of surface accuracies (form errors) and how the choice of cutting strategies affects these, as well as simplifying the complications of generating cutting paths for such freeform surfaces. The breakthroughs behind this thesis are the development of novel, multiple-axis, diamond turning techniques to overcome the limitations of conventional diamond turning processes, an analytical model to optimize the generation of ultraprecise freeform surfaces, and an add-on tool path processor for CAD/CAM software solutions. It appeals to researchers and scholars with a strong machining background who are interested in the field of manufacturing ultraprecise freeform surfaces or in the field of optimizing ultraprecision machining processes.

Autorenporträt
Dennis Neo Wee Keong obtained his bachelors degree in Mechanical Engineering from National University of Singapore in Singapore in 2010. He continued to pursue his doctoral studies at National University of Singapore in 2011, under the supervision of Prof A. Senthil Kumar and Prof Mustafizur Rahman, and after an exciting 4 years, graduated with a PhD in 2015. Currently, he is Research Fellow under the same research group focusing on the challenges in the deep-hole drilling/large format machining of difficult-to-machine materials. His research interests are in ultraprecision machining of freeform surfaces using multiple-axis ultraprecision machining techniques, such as fast tool/slow slide servo, with proper analytical of surface errors to optimize process.
