The second order gives worthy performance of the grinding. The results indicate that the optimum parameters for the grinding model are 20 m/min table speed and μm depth of cut for singlepass grinding. For multiplepass grinding, optimization is at a table speed equal to m/min and a depth of cut equal to μm.
properties of nanofluids may enable MQL grinding. • Formulation of new nanofluids for practical MQL grinding application. • Study of convection heat transfer performance of nanofluids. • Grinding temperature measurement and thermal model development for MQL grinding using nanofluid. • This research is sponsored by NSF and General Motors.
The remarkable enhancement in heat transfer capabilities of conventional fluids with the addition of nanosized metallic and nonmetallic particles appealed the attention of investigators towards the suspension of hybrid nanocomposites as a substitute of mono particles.
A colloidal mixture of nanometersized (<100 nm) metallic and nonmetallic particles in conventional cutting fluid is called nanofluid. Nanofluids are considered to be potential heat transfer fluids because of their superior thermal and tribological properties. Therefore, nanoenhanced cutting fluids have recently attracted the attention of researchers.
