顺逆混合铣-铣复合加工方法的切削力分析
|
摘要
难加工材料已广泛应用,但加工过程中出现了的切削力大、刀具寿命短等诸多问题,提出了在不降低材料去除率的前提下有效地降低切削力的大小的新方法铣-铣复合加工方法,顺逆混合铣-铣复合加工方法是铣-铣复合加工方法的一种形式,顺逆混合铣-铣复合加工方法中的刀盘在低转速下就能实现高速切削。顺逆混合铣-铣复合加工方法中将总磨损量平均到了不同立铣刀的不同的切削刃上从而提高了整个刀具的寿命,从方法上解决了难加工材料加工中刀具寿命短的难题。实验结果表明顺逆混合铣-铣复合加工方法发挥了铣-铣复合加工方法组合优势,部分切削力能够相互抵消,从而减小加工工件的受力。
Difficult-to-cut materials have been widely used in many industrial areas,However,high temperature and high stress occur during cutting processes,which worsen machining conditions,reduce the life of cutting tools,and lower machining efficiency. A new processing method called the milling-milling machining method to reduce the cutting force without reducing the material removal rate was proposed. The up down milling-milling machining method which belongs to the milling-milling machining method can realize high-speed cutting when the cutter body has low speed. The up-down millingmilling machining method also improved tool life by averaging the total amount of wear in all end-milling cutting edges. The experimental results illustrate that the up down milling-milling machining method can offset a portion of the cutting forces to reduce the stress of workpiece.
