An experimental investigation into the effect of process conditions on the mass concentration of cutting fluid mist in turning

Cutting fluid mists that are generated during machining processes represent a significant waste stream as well as a health hazard to humans. Epidemiological studies have shown a link between worker exposure to cutting fluid mist and an increase in respiratory ailments and several types of cancer, prompting closer scrutiny from several regulatory agencies. In this work, statistically designed experiments were conducted to determine the machining conditions that have the most significant effect on PM10 and PM2.5 mass concentration levels of cutting fluid mist during a turning operation. Identification of these significant factors may lead to modifications in the machining process as a solution for minimizing cutting fluid mist, thus eliminating/reducing the need for costly mist control technology such as air filters, enclosures, and fluid additives.
