Study Notes
Minimum Quantity Lubrication (MQL) Machining
- MQL is a green cutting technology that uses a minimal amount of cutting fluid to replace traditional flood cutting. It aims to improve sustainability by reducing environmental pollution and waste.
- MQL system parameters affect cutting performance like cutting force, cutting temperature, residual stress, tool wear, and surface quality.
- MQL system involves the use of a mist of cutting fluid, typically combined with air or nitrogen.
- Existing MQL technology is being improved in four main areas: cryogenic MQL, MQL atomization improvement, MQL and additive combinations, and MQL equipment improvement.
- MQL can be implemented in various ways with different levels of effectiveness, including external jet MQL for turning, grinding, low-speed milling and internal supply MQL for drilling and high-speed milling.
- Air pressure plays a crucial role in the effectiveness of MQL, directly affecting droplet size distribution.
- Future research focuses on developing a complete theoretical system to define process parameters accurately and investigate the lubricating and cooling mechanisms of MQL at the micro level.
- The development of a comprehensive MQL cutting database is crucial for finding optimal cutting conditions and providing a reliable reference for engineering applications.
