    摘要:

    介绍了在传统切削和高压喷射辅助切削方式下WC/Co硬质合金刀具对钛合金Ti17的加工,并进行了对比分析。在不同的切削速度和喷射压力下,研究了刀具的磨损演化以及切削力和轴向力的变化,并进行了相应讨论。在切削速度为50~100 m/min和喷射压力为5~25 MPa之间进行试验,确定了最佳润滑喷射压力和切削速度。当喷射压力为10 MPa时,最佳切削速度vc为8140 m/min,与常规润滑方式相比,刀具寿命提高约9倍,效率可提高约30%。

    Abstract:

    The machining of titanium alloy Ti17 with WC/Co cemented carbide cutting tools under the traditional cutting and highpressure water jet assistance cutting methods was introduced, and a comparative analysis was made.Under the different cutting speeds and the water jet pressures, the evolution of tool wear and the changes of cutting forces and axial force were studied,the corresponding discussion was also carried out. The optimum water jet pressure and cutting speed were determined by experiments between cutting speed of 50~100 m/min and water jet pressure of 5~25 MPa. When the water jet pressure is 10 MPa,the best cutting speed is 8140 m/min.Compared to conventional lubrication,the tool life is increased by about 9 times and the efficiency is increased by about 30%.
