The proposed research has been performed to know the characteristics of cutting fluid aerosol formation using Dual-PDA system in machining process. The cutting fluid aerosol size and concentration is common attributes that quantify the environmental intrusiveness or air quality contamination. The atomized cutting fluid aerosols can be affected to human health risk such as lung cancer and skin irritations. Even though cutting fluid can be improved the machining quality and productivity in a carefully. its use must be controlled and optimized carefully. This experimental works using Dual-PDA were performed to analyze the cutting fluid aerosol behaviors and characteristics in turning process using precise aerosol particle measuring system. The obtained experimental results profovide basic knowledge to develop the environmentally conscious machining process. This results cail be provided as a basis to estimate and control the hazardous cutting fluid aerosol in machining process.

This paper presents the analytical approaches to predict cutting fluid aerosol formation characteristics in machining process. The prediction model which is based on the rotary atomization theory analyzes aerosol behaviors in terms of size and concentration. Experiments were tarried out to verify the aerosol formation prediction model under various operational conditions. The experimental results which are obtained by Dual-PDA measurement show resonable agreement with prediction results of aerosol concentration. This study can be provided as a basis to estimate and control the hazardous cutting fluid aerosol in machining process in view of environmental consciousness.
