Sustainable milling with Minimum Quantity Lubrication

Important results from the project

The project could answer the below research questions. 1. What are the main challenges in implementing MQL in milling in industrial applications? 2. What are the most challenging parameters to control when milling ISO K with MQL, such as surface finish, tool wear, cutting forces, temperature and chip removal? 3. What factors have the greatest impact on the performance of the MQL setup in milling? 4. What are the appropriate combinations of factors for optimal results of MQL in milling?

Expected long term effects

The results of the machining trials not only helped answer the project´s research questions but also provided important insights into the potential as well as the challenges of MQL applications in milling processes. The project has been an important first step in bringing MQL in milling closer to industrial application, and it provides a strong benchmark for future research.

Approach and implementation

The core of the project was the machining trials. This was done by designing an experimental study with factors and evaluation parameters. The project faced delays due to maintenance activities in machining, which led to an extended project time. However, the results were very rewarding. One of the important results of the project was good cooperation between the parties in the consortium, which has led to opportunities for future collaborations.
