Development of an alignment process for raw parts based on photogrammetry for the machining of large components

This thesis falls within the area of photogrammetry with retro-reflective optical markers applied to high-end dimensional metrology. The development of a blank workpiece alignment process is proposed based on photogrammetry, which is aimed at increasing the simplicity and efficiency of this industrial process. This process is a critical limiting factor for productivity achievable in the manufacture of large components, and is made up of two measurement systems: than 100 m3. [...]

Active lubricated guidance for precision tool machines based on adaptive valves and fluids

The research work presented in this report had the objective of advancing knowledge on pressurised lubricated hydrostatic, hydrodynamic and hybrid slideways. Work with conventional fluids and magnetic fluids was carried out, and in both cases improved performance with respect to conventional passive solutions and an advanced active response was achieved.

Application of variable speed strategies for the optimization of the grinding process

The main objective of this research, in which the present doctoral thesis is contextualized, is the development of strategies for the optimization of the set-up and the analysis of grinding processes, focusing on infeed configurations of cylindrical and centerless grinding and throughfeed and traverse configurations of centerless and cylindrical grinding respectively. Those strategies are based on the application of commanded variable speeds over the main parameters that govern the process: the feed rate, the workpiece speed (or the regulating wheel speed for centerless grinding) and the grinding wheel speed. [...]

Milling stability improvement through novel prediction and supression techniques

Chatter is one of the main problems in today·s milling processes. Theoretical models for the calculation of stability lobes are available to predict and prevent chatter. However, predictions done with milling stability models are not robust, and all too often the discrepancy between prediction and reality are significant. [...]

Contributions to pre-processing, processing and analysis in infra-red thermography applied to non-destructive testing

The use of non-destructive measurement techniques by means of Infra-Red Thermography (IT) allows a fast and simple evaluation and control of all types of materials and processes without any contact. For this reason, the general objective of this thesis was to better understand the different stages of digital treatment of thermograms, to apply this new knowledge to real problems and to find solutions for any deficiencies.

Development and Improvement of Optical Tracking Methods towards Registering the Deformations of 3D Non-Rigid Bodies in Real Time for Augmented Reality Applications

This thesis tackles the improvement and development of the main optical tracking techniques, primarily focused on detecting the deformations of the bodies. First, it has been achieved the tracking of rigid and non-rigid planar surfaces through a monocular camera, and then, the object deformation estimation with a more complex device as a RGB-D camera has been developed.
