现代工业技术的迅速发展,引入了很多高强度、高硬度和耐高温等难加工材料,这些材料加工时,切削力大、切削温度高、刀具磨损严重、加工表面质量差。通电辅助切削技术是改善难加工材料切削加工性能,提高表面质量、提高刀具耐用度的有效方法。目前,已有国内外学者对通电辅助车削技术进行深入研究,尚未有学者研究通电辅助铣削技术。 本文针对通电辅助硬铣削加工工艺及监测展开一系列的研究工作。提出了通电加热辅助铣削方法,在辅助加热电极与工件间通以直流低压、大电流,利用其接触电阻产生大量焦耳热,使工件加工点局部温度快速升高并软化,从而达到提高切削效率、提高铣刀寿命的目的。搭建了通电辅助硬铣削试验平台,包括通电加热系统,以...With the rapid development of modern industrial technology, a lot of high strength, high hardness and high temperature resistant materials have been introduced, which caused some problems, such as large cutting force, high cutting temperature, serious tool wear and poor processing surface quality. Electric assisted cutting technology has been regarded as an effective method against the hard-to-mac...学位:工学硕士院系专业:物理与机电工程学院_航空宇航制造工程学号:3202010115268
