the MQL setup were varied and its influence on the surface texture, forces, chip morphology were studied and presented. 2. MQL grinding of Titanium alloys The Titanium alloy is the most widely used material for aerospace and defense applications. Their unique property of .
Utilization of Teflon and Aluminum Oxide for Wheel Cleaning in Minimum Quantity Lubrication (MQL) Grinding The cutting fluid used in conventional flood coolant application was Quimatic ME-I semi-synthetic soluble oil, with 2.5% concentration, applied at a flow rate of 17 L/min. This fluid contains in its composition anticorrosives,
H1224 surface grinding machine with the following conditions: grinding parameters: wheel speed (10.89, 16.34 and 21.79 m/sec), table speed (3, 9 and 15 m/min) and depth of cut (10, 20 and 30 µm). The flowrate and air pressure for the MQL grinding are 18ml/hr and 1.5bar respectively. The
were carried on a Tool and cutter grinder (Schuette make) grinding machine with a resin bonded diamond wheel. Grind-ing wheel specification and machining parameters for various grinding environments such as dry, MQL and Cryo-MQL are tabulated in Table 1. The experimental setup with all mea-suring sensors for Cryo-MQL grinding is shown in Fig. 1.
Materials 2018, 11, 2269 3 of 20 (surface roughness, temperature, and force) using MQL grinding process. The authors get motivation by the fact that insufficient work has been done on the multi-objective optimization of grinding of AISI
The aim of this work is to examine the potential of Al 2 O 3 nanofluid under MQL mode to improve the grinding characteristics of Ti-6Al-4V alloy. 1% Volume concentration of water-based Al 2 O 3 nanofluid was applied during the surface grinding operation using an indigenously developed MQL setup and the results have been compared with those of ...
