초록

Currently, the mobile device is required to be miniaturized and lightweight according to the needs of the consumer. For this purpose, each part is produced and assembled in units of modules. Accordingly, the display part is also composed of a cover glass, a touch screen, And it costs a large amount to replace the whole when it is damaged. Therefore, we propose a method to improve the durability of display part using ANOVA (Analysis of Variance) and MR fluid polishing. Before MR fluid polishing process, surface treatment was performed to obtain a polishable surface. A series of experiments were carried out to very fine surface roughness and to secure durability of cover glass. Polishing depth, feed rate, and abrasive size were selected to examine the MR fluid polishing results.
