Experimental Investigations and Modeling of Temperature in the Work-Brush Interface during Ultrasonic Assisted Magnetic Abrasive Finishing Process

Ultrasonic assisted magnetic abrasive finishing (UAMAF) integrates ultrasonic vibrations and magnetic abrasive finishing (MAF) process to finish surfaces to nanometer order. During a finishing operation the order of temperature rise is important to study as cutting mechanism, wear, finishing accuracy, and surface integrity of work materials depend on it. In the present study, temperature measurement at workpiece-magnetic brush interface at various positions during UAMAF has been carried out at different processing conditions. Buckingham's dimensional analysis has been used to model this temperature, and the required coefficients are calculated based on the experimental data to predict temperature. The developed empirical model based on dimensional analysis has been validated and was found to be in good agreement with experimental findings.
