The Study of Precision Electrical Machining Process for Flexure Hinge

摘要

Flexure hinge is required for various types of prccision instrument and precision fine stage. The accuracy of flexure hinge is a problem in mechanical machining processes and the ratio of end product is low. This paper proposes a combined electrical machining process of electrical discharge machining (EDM) and pulse electrochemical machining (PECM) for the production of flexure hinge without deformation and residual stress. Its application achieved notable results.
