电流变凝胶（ERG）是一种新型的功能材料，其表面摩擦和粘附特性随外加电场强度的变化而变化。在最近的一项研究中，将单面图案化电极应用于ERG，并通过实验证实了电场下表面摩擦和粘附特性的变化，称为ERG效应。具有单侧图案化电极的ERG被认为适合应用于用于微铣削的夹具装置。在这项研究中，ERG夹具装置的原型开发和其性能进行了实验研究。所提出的ERG固定装置可用于固定金属和非金属工件，例如玻璃。ERG的微收缩与施加到ERG材料的电压成比例地发生。利用这一特性，还可以调整工件的对准。将研制的ERG夹具应用于薄玻璃工件的微槽加工，取得了成功的结果。
Electro-rheological gel (ERG) is a new functional material whose surface friction and adhesive properties vary according to the intensity of the applied electric field. In a recent study, one-sided patterned electrodes were applied to the ERG and the change in surface frictional and adhesive property under the electric field, which is called the ERG effect, was experimentally confirmed. The ERG with one-sided patterned electrodes is considered to be suitable for application to a fixture device for micro milling. In this study, a prototype of the ERG fixture device was developed and its performance was experimentally investigated. The proposed ERG fixture devices can be useful for fixturing both metallic and nonmetallic workpieces, such as glass. Micro shrinkage of the ERG occurs in proportion to the voltage applied to the ERG material. Using this characteristic, the alignment of the workpiece can be also adjusted. The developed ERG fixture device was applied to the micro grooving process of a thin glass workpiece, and successful results were obtained.
