A REVIEW, EVALUATION AND COMPARISON OF CUTTING FLUID USED IN CNC LATHE MACHINING

Abstract

Cutting fluid are majorly used in machining process to reduce temperature, cutting forces and thus extends the
tool life. Cutting fluid contain complex components, different ingredients some of which are toxic in nature. However due
to this constant exposure to these fluids causes health hazards to the workers. Further chemical treatment is required
cause of disposal of the cutting fluid on the machined material increases the cost. To make cutting fluid more benign,
vegetable-based compounds are being used to replace the toxic ingredients of existing cutting fluid. This is done in
different levels, i.e., either only the mineral oil or even the emulsifier is replaced by a vegetable alternatives.
