The influence of minimum quantity of lubrication (MQL) on cutting temperature, chip and dimensional accuracy in turning AISI-1040 steel

Minimum Quantity Lubrication Assisted Turning - An Overview

“…However, the oil mist levels on shop floor are quite high; oil mist level of 1-56.5 mg/m 3 , 0.8-50 mg/m 3 and 20-90 mg/m 3 was reported for flood type of cooling in automobile manufacture, manufacture of steel products and automotive plants respectively (Benett and Benett, 1985). Also, the use of coolant fluid costs from 7 to 17% of the total manufacturing cost of work-piece (Weinert et al, 2004) and requires additional time for work-piece/tool/machine cleaning (Dhar et al, 2006a). Moreover, a study conducted by Sutherland et al (2000) reveals that 12-80 times more cutting fluid mist was generated with wet turning, than cast iron dust in dry turning.…”

Optimization and Effect of Process Parameters on Tool Wear in Turning of Titanium Alloy under Different Machining Conditions

“…After Regression analysis, the final second order regression model is given by: VB = 0.591 -0.00444×X1 + 0.0178×X2 -0.00340×Vc -3.07×F -0.09318×D + 0.0378×Y1 -0.00444×Y2 + 5.34×F×F + 0.0565×D×D + 0.000031×Vc×Vc (3) where VB = Tool wear rate; Vc = cutting speed; F=feed rate; D= depth of cut; and X1, X2 and Y1,Y2 are the indicator variables of type of machining environment and tool materials respectively.…”

“…The experimental results indicate that MQL enables substantial reduction in the cutting temperature, tool wear, dimensional inaccuracy depending upon the levels of the cutting speed and feed rate [3]. Furthermore, MQL provides environment friendliness, maintaining neat, clean and dry working area, avoiding inconvenience and health hazards due to heat, smoke, fumes, gases, etc.…”

Performance evaluation of coated carbide tool in machining of stainless steel (AISI 202) under minimum quantity lubrication (MQL)

“…However, few disadvantages make the MQL-based machining process impractical to be adopted in many industrial production settings. 6 The review of literature has revealed that majority of work on MQL machining has carried out on various grades of hardened alloy steels: AISI-1040, AISI 1045, AISI 1060, AISI-4340, Ni-Cr alloys like Inconel 718, brass and aluminum alloy 6061and titanium etc., [7][8][9][10][11][12][13][14][15][16] and a few researchers have explored MQL machining potential of stainless steel grades. Leppert 17 investigated surface layer properties of AISI 316L stainless steel when turning under dry and MQL conditions.…”
