Condition Monitoring Condition Monitoring


  • Machine monitoring using machine learning techniques appropriate for application in dynamic environments, where failures are not very common and are related to degradation.
  • Monitor in real time the status of the bearings with respect to the generated reference.

Develop AI Technologies

  • Data intelligence.
  • Machines/people interfaces.
  • Smart sensors.
  • Machine learning.
  • Pattern analysis, prediction and intelligent classification.


  • To develop machine monitoring system that allows failure detection in critical elements, in this case, the spindle header.
  • To develop first steps for the detection of anomalies in highly dynamic processes.


  • Dataset size: 1GB / day
  • Number of variables: 10 - 110
  • Sampling time: 50 - 100ms
  • It has been possible to develop data acquisition systems that ensure their quality by extracting them from production systems such as machine tools.
  • Once this quality was assured, the first machine patterns were developed.
  • These patterns have been examined and compared as a reference to detect possible deviations in relation to the reference.
  • This system allows monitoring the state of the front bearing of the spindle head. Its failure can cause the machine and production line to stop.
