Analysis of power in the drilling process to move towards new control strategies. Análisis de la Potencia en el Proceso de Taladrado para el Planteamiento de Nuevas Estrategias de Control (PT10048)

  • Lead researchers: Eva Portillo Pérez - (18/10/2010 - 18/12/2010)
  • Funding body: IDEKO, S. COOP.

The aim of this work is to analyse drilling process behaviour to evaluate the possibilities of designing a control system that allows us to increase productivity and to efficiently manage tools with a power supervision loop. In order to carry out this analysis we first propose a testing methodology to extract maximum knowledge about the process. This trial methodology involves trials in both a stable regime and degraded regimes caused by the wear or breakage of the tool. Second, it is necessary to define and...

Control strategies based on a model with redundant information to improve performance. Estrategias de control basadas en modelo con información redundante para la mejora de las prestaciones (DPI2009-07669)

  • Lead researchers: Itziar Cabanes Axpe - (01/01/2010 - 31/12/2012)
  • Funding body: Spanish Ministry of Science and Innovation

The aim of this project is to develop control strategies specifically for closed chain robots, where, given their complex kinematics and dynamics and the high fitting between the different kinematic chains, the control systems used until now have been decoupled and taken from serial robots. For this, we sensors are incorporated into the passive articulations or not actuated (partially or wholly) so this additional information will be used in the control strategies.

Application of intelligent control techniques in wire electrical discharge machining. Aplicación de técnicas de control inteligente en el proceso de electroerosión por hilo (UPV05/114)

  • Lead researchers: Itziar Cabanes Axpe - (01/12/2005 - 30/11/2007)
  • Funding body: University of the Basque Country

Based on results from previous projects (Empirical modelling of Wire electrical discharge machining to optimise the discharge quality, and Analysis and Diagnosis of discharge quality in wire electrical discharge machining), which show that, although the basic features of the degraded behaviours are the same in both thicknesses analysed, the thresholds met by virtual measures differ. Thus, we propose the definition of one structure that can automatically adapt parameters in a given range of thicknesses, with the aim of...
