Contribution to micro-milling process parameters selection for process planning operations

Vázquez Lepe, Elisa (Date of defense: 20-05-2014)
The development of new products with micro-metric characteristics and complex geometries has been a manufacturing trend in different industrial sectors, particularly for electronic, military, biomedical and aerospace ...
Optimització del procés productiu d'engreixament porcí. Un enfocament operatiu

Castro Vila, Rodolfo de
Aquest treball de tesis doctoral tracta de la Optimització de la fase d'engreix. L'objectiu és determinar les condicions d'enviament a sacrifici d'un lot d'animals des d'un punt de vista operatiu. En primer lloc es fa una ...
Contribution to laser milling process parameters selection for process planning operations

Teixidor Ezpeleta, Daniel (Date of defense: 17-10-2013)
Nontraditional manufacturing processes (NTM) appeared to answer the growing demands of market productivity. Needs of higher quality products in less time and new demands such as new exotic work materials, innovative geometric ...
Stability lobes diagram identification and surface roughness monitoring in milling processes

Quintana i Badosa, Guillem
La millora de la productivitat i la qualitat són indubtablement dues de les principals exigències del sector productiu modern i factors clau per la competitivitat i la supervivència. Dins aquest sector,la fabricació per ...
Milling stability improvement through novel prediction and suppression techniques

Iglesias, Alex (Date of defense: 04-02-2016)
Chatter is one of the major problems in today’s milling processes. Theoretical models to calculate stability lobes are used to predict and avoid chatter onset. However, current predictions are not accurate enough and ...
Contributions to ultrasonic micro-moulding process of high performance polymers

Dorf, Tomasz (Date of defense: 05-06-2019)
Polymeric materials, which are suitable for high performance applications for example human implants are one of the most expensive available polymers. Standard injection micromoulding process, dedicated for mass production, ...
Contribution to bioabsorbable stent manufacture with additive manufacturing technologies

Guerra Sánchez, Antonio (Date of defense: 06-06-2019)
The main motivation of this work was to analyse the feasibility of the current stent’s manufacturing process to produce the new bioresorbable stents (BRS) as well as study new manufacturing methods. Fibre Laser Cutting ...
A mechano-perfusion bioreactor for tissue engineering

Fernandes Freitas, Dino Miguel (Date of defense: 29-11-2019)
Tissue Engineering plays a vital role in tissue construct to repair, maintain or replace tissues. Those tissues can be cultivated in vivo or in vitro using devices such as bioreactors. There are several approaches to ...
