Modeling of the environmental effect of cutting fluid

This paper presents the establishment of a parametric model describing the amount of,metalcutting fluid departing from the machining area and permeati ng into the shop floor environment. The analysis focuses on the process of horizontal turning with overhead fluid jet application. The portion of flui d that leaves the machining area and does not land on the fluid pen is cons idered cis the permeating cutting fluid that contributes to environmental c ontamination. The quantitative model developed in this analysis accounts fo r three primary mechanisms of which metalworking fluid enters into and enda ngers the shop floor environment. The three primary mechanisms are the evap oration of fluid resulting from high temperature in the cutting zone, spin- of of fluid from the workpiece due to rotational motion and the splash due to kinetic energy from fluid-workpiece impact. Process parameters and fluid properties found to affect these mechanisms include part diameter; rotatio n speed, fluid velocity, fluid viscosity and tool temperature. The validity of the model has been evaluated experimentally render both conditions of s tationary and rotational workpiece.
