摘要
针对普通微钻削中Ti6Al4V钛合金存在的排屑难、温升快及易断刀等问题,对Ti6Al4V钛合金进行微孔钻削Deform-3D仿真和试验研究,通过仿真分析普通钻削、分离型超声振动钻削及非分离型超声振动钻削的钻削温度和钻削力,通过试验比较超声振动钻削和普通钻削的钻削力并分析分离型超声振动钻削的优点。结果表明:超声振动钻削相较于普通钻削轴向力可以降低19%左右,温度可降低24%左右,超声振动钻削和普通钻削的轴向力均随着进给速度的增加而增加,分离型超声振动钻削的钻削力相较于非分离型超声振动钻削可降低21%。
To solve the problems of difficult chip removal,fast temperature rise and easy tool breaking in the ordinary micro drilling of Ti6A14V titanium alloy,the DEFORM-3D simulation and experimental research of microdrilling of Ti6A14V titanium alloy are carried out.The drilling temperature and drilling force of common drilling,separated ultrasonic vibration drilling and non separated ultrasonic vibration drilling are analyzed through simulation.The cutting forces of ultrasonic vibration drilling and common drilling are compared through experiments,and the advantages of separated ultrasonic vibration drilling are analyzed.The results show that compared with common drilling,the axial force of ultrasonic vibration drilling can be reduced by about 19%,and the temperature can be reduced by about 24%.The axial force of ultrasonic vibration drilling and ordinary drilling increases with the increase of feed speed,and the drilling force of separated ultrasonic vibration drilling can be reduced by 21%compared with non separated ultrasonic vibration drlling.
