Technique of Comparison and Optimization of Conditions for Magnetic Abrasive Finishing
Baron, Yuri M.,Ko, S.L.,Park, Jung Il Trans Tech Publications, Ltd. 2005 Key Engineering Materials Vol.291 No.-
<P>In this paper, the new technique involving comparison and optimization of conditions for Magnetic Abrasive Finishing (MAF) is suggested, taking into account the basic laws stated for process MAF. The formulas for the calculation of the criteria for optimization are created when the process MAF is used for polishing, removal of burrs, and other purposes. The application of the technique is shown in an experiment on the optimization conditions for the removal of burrs after drilling using the MAF method. The technique can be used after standards for this process are developed.</P>
Characterization of the Magnetic Abrasive Finishing Method and Its Application to Deburring
Baron, Yuri M.,Ko, S.L.,Park, Jung Il Trans Tech Publications, Ltd. 2005 Key Engineering Materials Vol.291 No.-
<P>This paper analyzes the effectiveness of using Magnetic Abrasive Finishing (MAF) to remove burrs on drilled holes located on planes. Basic elements of the equipment in this method are a magnetic inductor; powder with magnetic and abrasive properties, which serves as the cutting tool; and the face electromagnetic inductor and the vibrating table, which were developed for deburring and finishing on flat surfaces. The performance of magnetic abrasive powders produced by industry is also evaluated. A new technique was developed to compare the performance of the magnetic abrasive powders and to find the powder that is appropriate for finishing and deburring drilled holes placed on a plane steel surface.</P>

Micro burrs formed in micro parts are not subject to be removed by the conventional deburring method for marco parts. .Magnetic abrasive deburring method which was proved .to be effective for small burrs are applied for deburring the micro burr in electric gun parts used in TV monitor. A specific magnetic inductor is designed and manufactured for this part. To improve the deburring performance, vibration table is used for increasing the relative velocity. To evaluate the deburring capability and surface finishing, edge shape, surface roughness and composition of surface material are measured precisely. It is verified the chemical composition of surface is not affected by the powder composition when the proper powder are used with coolant.

The performance of magnetic abrasive finishing for surface is evaluated by the characteristic curve. The characteristic curve is generated by experiment in surface finishing. For experiment, new magnetic inductor is designed and manufactured. 15 kinds of powders are provided to find the relationship between powder characteristic and finishing performance. As powder, Fe-TiC, Polymer-TiC and Fe-NbC are used with different size. The size of abrasives and location are also important factor for the performance. From characteristic curve, two index are obtained, which specify the initial finishing performance and endurance of finishing performance. It is proved that the performance index can be applied to select proper powder. for efficient deburring. It is shown that the characteristic curve can be used as good tools for evaluating powder performance in surface finishing and deburring.
