impact

  • 8% improvement in machine availability.
  • Improved machine design by detecting the part of the machine that is most sensitive to thermal changes.

Developed AI Technologies

  • Data intelligence.
  • Smart sensors.
  • Intelligent automation.
  • Machine learning.
  • Pattern analysis, prediction and intelligent classification.

Challenges

  • To increase in machine availability in through high temperature gradients in production facilities. Due to these gradients, the machine/manufacturing line had to be idle around 2 hours.
  • Support to the PLC/CNC compensation system to withstand extreme temperature changes.
  • Improvement of the machine design according to the study of the sensitivity of different parts of the machine to extreme changes in temperature in a real productive environment.
  • To complement analyzes done with finite elements during the machine design phase.
Correlation between temperature and machine structure.
