Effects and mechanisms in minimal quantity lubrication machining of an aluminum alloy

Minimum Quantity Lubrication Assisted Turning - An Overview

“…A study on effects and mechanisms in MQL intermittent turning of Aluminum alloy (AlSi5) was conducted by Itoigawa et al (2006). MQL was studied with oil and oil film on water droplet using rapeseed oil and synthetic ester as lubricant.…”

Improving tool life using cryogenic cooling

“…The most practical and effective way to enhance the machining performance in cutting difficult-to-cut materials is to reduce cutting temperature (Evans, 1991a;Wane et al, 1996;Itoigawa et al, 2006 Ezugwu et al (Ezugwu et al, 2007) when machining Ti-6Al-4V with high-pressure coolant supplies and the recorded surface roughness values were found to be below the tool rejection criteria. But during machining of Ti-6Al-4V the performance of CBN tools in terms of tool life was found to be poor compared to uncoated carbide tools and probably it is due to rapid notching and excessive chipping of the cutting edges (Ezugwu et al, 2005a).…”

Oil-on-Water MQL Machining of Nickel Based Super Alloy Nimonic C.263.

“…Studies show that size of the particles could be essential for effectiveness of MQL machining. Reported effectiveness of this system [2,12,17] indicates that size of OoW droplets could still be in acceptable range. MQL system settings are as follows: oil consumption is in range from 10-50 ml/h and water from 300 to 1800 ml/h.…”

“…However, due to the high initial costs of cryogenic machining systems, application and development of MQL machining systems is in constant up rise. One of examples of MQL machining which performs similar as flood machining (or even better [3,12]) is advanced MQL machining with external supply of aerosol that includes compressed air, oil and water. The system supplies machining zone with water droplets covered with thin oil film.…”
