Abstract
ERG (Electro rheological gel) is a functional material whose frictional property changes according to the applied electric field intensity. In this study, developed ERG is applied to fixture device. It is easy to fix and detach a workpiece due to applying and releasing a voltage to ERG fixture. Moreover, ERG fixture can fix a workpiece without external force, therefore workpiece does not bend. The prototype of ERG fixture is manufactured and its characteristic is evaluated by glass cutting test. The result shows that ERG fixture has enough friction force to fix the glass workpiece and the vibration of workpiece was reduced by higher applied voltage. In addition, it is clarified that ERG fixture with the special patterned one-sided electrode, whose electrode width is changed, is effective for micro alignment.
