Research on a Method of EDM Control System Based on Two Positioning Mode

Article Preview

Abstract:

The processing of three-dimensional structure and servo feed systems for micro-EDM have strict requirements.The two positioning method is used to solve the contradiction between the large stroke and high precision, Coarse and fine action units matched to achieve the precision positioning requirements. A combined device with piezoelectric ceramic and step motor has been employed as drive and use the linear rolling guide As the transmission in this study,which has strong control function ,great flexibility, high positioning accuracy and repeatability. The basic performance of the platform met the needs of micro-EDM control.
