Condition Monitoring of Cutting Processes
Quality Assurance of Fiber Production
Lenzing produces a wide variety of fibres from the raw material wood. The fibres are later used for both textiles and technical tiles.
During the production process, the fibres have to be cut into short pieces.
The wear of the cutting blades has an influence on the quality of the end product, as well as on noise, vibrations and energy consumption.
For economic reasons, however, the cutting blades should not be changed too often.
A condition monitoring system was implemented with LCM to automatically monitor wear and determine the ideal time to replace the cutting blades.
Challenge
- Identify the correlation between process parameters and fiber cut quality
- Measurement and analysis of vibrations, noise emissions, electrical drive currents
Solution
- Improved maintenance planning with blade wear information
- Predictive condition monitoring of the cutting system
