The effect of portable MQL applicator onto carbide insert during turning Inconel 718

Abstract

Turning operations are a versatile secondary metal cutting process. In metal cutting industry, manufacturing processes are designed to attain minimum manufacturing cost, best quality and improved cutting tool's performance. Nonetheless, the deterioration of cutting tools, occupational diseases amongst the workers and environmental aspects are increasingly becoming a major issue. Therefore, one alternative to reduce the impact of metal cutting activity in term of cutting tool, the health and environment is Portable MQL Applicator. The portable MQL applicator is an equipment that equipped with pneumatic system to deliver a small amount of fluid in the form of aerosol into the cutting zone. The effect of the portable MQL applicator was investigated and compared with the results from dry machining in terms of tool life and material removal rate in turning of Inconel 718 using carbide tool. The results showed that the applications of the portable MQL applicator have successfully resulted in better tool life and improved material removal rate.

Analysis of tool vibration and surface roughness with tool wear progression in hard turning: An experimental and statistical approach

“…This reduces post processing of cutting fluid in terms of its storage and dumping, and also decreases part cost up to 70% [5][6]. But some analysts support utilization of cooling media in view of better surface finish and low tool vibrations [7][8].…”

Environmentally Friendly Approaches Assisted Machining of Aluminum Alloy 7075-T6 for Automotive Applications: A Review

“…MQL or pseudonym of near-dry is modern machining that applies a small amount of fluid into a form of mist particles and then penetrate into the cutting zone. The definition of this approach is synonym with the cutting fluid in which capable to act in reducing friction, wear and flush away the chips at desired cutting speeds in manufacturing processes [6], [7], [8]. Cryogenic means the viable operation to propel the liquid gases form to the cutting zone and operated at lower Abstract: Nowadays, aluminum alloy 7075-T6 has received a high demand in the automotive industry due to its advantages in the aerospace industry, which possessing exceptional mechanical combinations and chemical elements such as high tensile strength, high strength, high corrosion resistance, zinc, magnesium, and copper to increase their strength.…”

Effect of Minimum Quantity Lubrication and Dry Cutting on the Tool Life and Chip Morphology after Milling of Aluminum Alloy 7075-T6

“…MQL is an approach which sprays the cutting fluid in a small amount in the range of 10 to 100 mL/h into the cutting zone with the assisted by compressed air while the dry cutting in relation to the cutting process without the cutting fluids [4]- [6]. The dry cutting was practicable in the various cutting process, but it may potential leads to a reduction of cutting tool life and machined surface quality as well as poor chip flow.…”
