Analysis of wire electrode temperature fields and kerf fluid flow for multi-cutting in WEDM
摘要
Abstract
To solve the instability problem of muhi-cutting wire electrode space position in High Speed Wire Electrical Discharge Machining (HS-WEDM),firstly,the surface heat flow density model of wire electrode is established,the relationships among,and wire electrode heat flux density are discussed.A new view is proposed that it is very important to apply narrow pulse width and high current in multi-cutting.Based on these,the wire electrode temperature fields and gap fluid flow are studied by building a 3D kerf model.The results show that the kerf inlet pressure of working fluid have a significant impact on the temperature field distribution of wire electrode,and the velocity of working fluid decrease is very large at kerf inlet.The results have guiding significance for stabilizing multi-cutting wire electrode space position.关键词
