摘要
针对钛合金Ti6Al4V加工过程中产生的切削热导致刀具的快速磨损这一工艺难题,进行了不同冷却条件下的铣削加工实验。借助扫描电镜分析(SEM)、能谱分析(EDS)等分析手段,研究了刀具的磨损形态及磨损机理。研究表明,粘结磨损是加工钛合金过程中刀具的主要磨损形式,切削液的使用并不一定提高刀具寿命,而机床的稳定性能对刀具磨损有较大影响。
High cutting temperatures produced during high speed milling Ti6Al4V process leads to rapid tool wear.Aimed at this problem,the milling experiments are performed under dry and wet cooling conditions.The inserts used in the experiments are investigated to understand the mechanism of tool wear by the aid of SEM and EDS technology.It is found that the adherent depositions of the titanium material on the insert face lead to tool wear,but the improper use of cutting fluid may decrease the tool life.Stability of machine tools influence the tool life greatly too.
