A comparative study on dry milling and little quantity lubricant milling based on vibration signals

Minimum Quantity Lubrication Assisted Turning - An Overview

“…The flow of lubricant in MQL process varies from 10 to 100 ml/h and air pressure varies from 4 to 6.5 Kgf/cm 2 (Silva et al, 2005). Different ranges for flow rate were also reported in literature such as 50 to 500 ml/h (Dhar et al, 2006a) and 2 to 300 ml/h (Zhong et al, 2010). However, in industrial applications consumption of oil is approximately in the range of 10-100 ml/h (Kamata and Obikawa, 2007).…”

Application of sustainable techniques in metal cutting for enhanced machinability: a review

“…The author concluded that in order to minimize the mist formation the MWF must be delivered to the rake face with the gas atomization pressure below 0.137 MPa and flow rate below 160 ml/h. In another work, Zhong et al (2010) used a new technique called little quantity lubrication (LQL) in which the fluid delivery rate was kept between 50 and 300 ml/min. The aim of the study was to enhance the machinability and alleviate the negative impact of cutting fluid by keeping the fluid flow rate lesser than that of MQL.…”

Effect of cutting fluids on corrosion properties and turning surface quality of Fe-based superalloy

“…Dry machining and minimum-quantity lubricant (MQL) machining have been developed to reduce cost and environmental impact. 5 Scholars from China 6 found that in rough machining, dry milling, and little-quantity lubricant (LQL) milling could decrease root mean square (RMS) value of vibration. In addition, high-pressure coolant assistance 7 and a pulse jet application of cutting fluids 8 have been investigated too.…”
