【摘要】：为了提高线切割加工的效率与效果,提出了二维超声振动线切割技术,从理论上对该技术加工机理与工艺进行探讨,利用Matlab软件进行仿真,对二维超声振动线切割中单颗磨粒的运动轨迹进行分析研究,从理论上证明二维超声振动线切割优于普通线切割和一维超声振动线切割.并利用自行研制的多线切割机模拟机进行切割实验,对比这三种切割方式,研究不同加工工艺参数对切割效率与加工表面质量的影响.实验结果表明:相同加工条件下,一维超声振动线切割相对于普通线切割,切割效率和表面质量都有明显提升,二维超声振动线切割相对于一维超声振动,大大提高了加工表面质量,切割效率有小幅提升.
[Abstract]:In order to improve the efficiency and effect of wire cutting, a two-dimensional ultrasonic vibration wire cutting technology is proposed. The machining mechanism and technology of this technology are discussed theoretically, and the simulation is carried out by using Matlab software. The motion trajectory of a single abrasive in 2-D ultrasonic vibration wire cutting is analyzed and studied. It is proved theoretically that two-dimensional ultrasonic vibration wire cutting is superior to conventional linear cutting and one-dimensional ultrasonic vibration wire cutting. The cutting experiments were carried out by using the multi-wire cutting machine simulator developed by ourselves. The effects of different processing parameters on the cutting efficiency and surface quality were studied by comparing the three cutting methods. The experimental results show that the cutting efficiency and surface quality of one-dimensional ultrasonic vibration wire-cutting are significantly improved compared with that of conventional linear cutting under the same processing conditions. The two-dimensional ultrasonic vibration wire-cutting is relative to one-dimensional ultrasonic vibration. The machined surface quality is greatly improved, and the cutting efficiency is improved slightly.
