The modern aircraft consists of tens/hundreds of thousands of components. A large proportion of these components are manufactured using a machining process. A deburring process must be performed after to machining. This study investigates the effect of changes in the deburring wheel rpm on the deburring force and radius. The deburring wheel is used to trim sharp edges off machined parts of the aircraft. The deburring wheel used consists of a core and a nylon hair(this new concept is protected under patent). We find that higher deburring wheel rpm results in increased deburring force and radius. For deburring wheel rotation rates of 500~750rpm, deburring force of 3.4~6.5kgf and deburring radius of 0.4~0.5mm were observed.

Deburring is conducted using MAF(magnetic abrasive finishing) method. Magnetic inductor is designed and manufactured to generate proper magnetic induction far deburring the burr formed in drilling SM45C. Rotational speed, table feed rate, grain size of powder and working gap are changed to investigate the effect on deburring.

Magnetic abrasive polishing is an advanced deburring process for nonmagnetic materials and micropattern products that have non-machinability characteristics. Despite these advantages, there are some problems with using MAP for deburring. MAP has introduced geometric errors into microgrooves because of an over-cutting force caused by uncontrolled magnetic abrasives in the MAP tool. Thus, in this study, to solve this problem, an EP (electrolyte polishing)-MAP hybrid polishing process was developed for deburring microgrooves in an STS316 material. In addition, an evaluation of EP-MAP for the deburring of microgrooves was carried out by profiling the burrs. The results of the experiment showed geometric errors after the deburring process using MAP. However, in the case of EP-MAP, no geometric error was observed after the process because of the lower material removal rate in EP-MAP.

The magnetic abrasive machining has been developed as a new finishing technology to obtain a fine surface of workpiece. In this paper, a static magnetic field method and a magnetic abrasive brush which has many technical advantages, are applied for the magnetic abrasive machining. In the experiment, some items such as finishing time, ratio of the magnetic abrasives to Fe-powder, motor revolutions per minute, and motor ratio revolutions per minute are tested. The results of this study have shown the fact that the burr height is mostly affected by the finishing time and the abrasive ratio. Also, it has been found that the magnetic abrasive machining is a possible new technology for the deburring.

In micro hole punching process the burr occurs inevitably, but the burr must be minimized in order to improve the quality and accuracy of the product. In this study, magnetic field-assisted polishing technique is applied to remove the burr which exists in nozzles for ink-jet printer head and proved to be a feasible for deburring by experiment. The deburring characteristics of sheet metals was investigated changing with polishing time and magnetic abrasive size. After the deburring, the burr size has remarkably reduced and roundness of the hole also has improved.

Due to the increasing demand for carious methodologies to improve the quality of products were introduced. A Brush the most frequently used type of grinding process is one of the deburring. in order to produce consistent burr shape, various machining conditions have been combined and applied to disk grinding process. Between the workpiece and the grinding disc to earn depends on the angle of the slope has been observed. Drastic increase of tool wear has been also observed along the inclination angle variation. Various burr shapes have been captured and analyzed using image processing technique.

We were interest in Deburring using MAF(magnetic abrasive finishing) method. So Magnetic inductor was designed and manufactured to generate proper magnetic induction fer deburring the burr formed in drilling SM45C. We experienced according to the Rotational speed, table feed rate, grain size of powder and working gap are changed to investigate the effect on deburring. At this time we experienced in abrasive effect mainly.
