| Abstract |
In order to enhance the cooling performance, better understanding of the effects of coolant
parameters is necessary. In this project, a total of five input parameters for actively cooled and
activated cutting fluid were studied. An aerosol spectrometer was used to measure the particle size
spatial distribution of the cooling mist in the fluid. Taguchi method was used in the design of
experiments. It was found that the unit volume net specific particle counts exhibit the behavior of
oscillation and attenuation of a second order dynamic system. Cooling mist particle spatial frequency
ranges from 0.01269/μm to 2.5/μm, the weighted average size ranges from 0.3051μm to 3.714μm and
the particle size difference for 99.8% count attenuation ranges from 0.5μm to 19.7μm. The order of
importance of the input parameters was studied and the coolant concentration was found as the most
important input parameter for the unit volume net particle counts. |
