Experimental Determination of Cutting Power for Turning and Material Removal Rate for Drilling of AA 6061-T6 Using Vegetable Oils as Cutting Fluid

الملخص EN

The raw and modified versions of two nonedible vegetable oils, Pongam (Pogammia pinnata) and Jatropha (Jatropha curcas), and a commercially available branded mineral oil are used as straight cutting fluids for turning AA 6061 to assess cutting forces.

Minimum quantity lubrication is utilized for the supply of cutting fluids.

Cutting and thrust forces are measured.

Cutting power is determined for various cutting speeds, depths of cut, and feed rates.

Also, drilling is performed on the material to understand the material removal rate (MRR) under these oils.

The performances of vegetable oils are compared to mineral oil.

A noticeable reduction in cutting forces is observed under the Jatropha family of oils compared to mineral oil.

Further, better material removal rate is seen under both the vegetable oils and their versions compared to under petroleum oil for the range of thrust forces.
