摘要: 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.

摘要: The sharp burrs produced by plastic deformation during machining of the precision components deteriorates the precision and performance of a machine. Thus, effective removal of the burrs may improve productivity and performance of the machinery. This study was conducted based on the experiment to remove fine burrs produced during machining process using the magnetic abrasive finishing method. The magnetic abrasive finishing using the abrasive feature of an abrasive and the magnetic nature of iron is an abrasive method to brush the burrs with iron powder that has a cohesive power due to the line of induction. The purpose of this study is to remove the burrs at intersecting holes which are difficult to access with tools, using the magnetic abrasive finishing method. Special tool is designed for deburring micro burr at intersecting holes. To find the proper deburring condition, gap distance, rotational speed of inductor, components of powder and effect of coolant are analyzed.

摘要: A nonlinear modeling of magnetic inductor with hysteresis using PSpice is presented. The describing functions are used to model the high frequency hysteresis to make up the defect of Jile-Atherton static hysteresis mathematical model. The subcircuits which include the nonlinear magnetic inductor are used to the circuit of filter by PSpice. The hysteresis-related characteristic of intermodulation distortion and corner frequency can be predicted by the improved inductor subcircuit models have been verified experimentally.

摘要: 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.
