Improvement of machining accuracy by fuzzy logic at corner parts for wire-EDM

摘要

Wire electrical discharge machining (wire-EDM)j has always occupied an important position in some production fields. Due to its capability of machining hard materials and intricate shapes. However, the machining accuracy, especially at corner Parts, may be destroyed because of some phenomena such as wire deflection and vibration, etc. The purpose of this paper Is to develop a control strategy based on fuzzy logic so that the machining accuracy at corner parts for wire-EDM can be Improved.
