图1(a)所示的切削力波形是用于通常精密切削的,图1(b)所示的脉动切削力波形是利用振动切削技术进行精密切削的。日本宇都宫大学根据这种振动切削,把连续的脉冲切削力波形改造成了如图1(c)所示的间断式波形,亦即开发了断续脉冲切削力波形的新型的重叠振动切削。这种重叠振动切削是一种让切削刀具沿切削方向以频率f、振幅a超声波振动,再使之以频率F、振幅A的低频振动,使切削速度v<2πAF进行振动切削的 The cutting force waveform shown in Fig. 1 (a) is used for general precision cutting. The ripple cutting force waveform shown in Fig. 1 (b) is precisely cut by the vibration cutting technique. Uchimi University in Japan based on this vibration cutting, the continuous pulse cutting force waveform into a discontinuous waveform shown in Figure 1 (c), that is, the development of intermittent pulse cutting force waveform of the new overlapping vibration cutting. This kind of overlap vibration cutting is a kind of cutting tool cutting the direction of the frequency f, the amplitude a ultrasonic vibration, and then make the frequency of F, amplitude A low-frequency vibration, the cutting speed v <2πAF vibration cutting
