Test Design of Testing Tool Three-vibration for Turning Aluminum Rod
【Abstract】Now machinery manufacturing technology rapid development, metal cutting to the development of high-speed cutting and powerful cutting direction, in the production process appear increase the possibility of vibration, cutting process more prone to vibration, how to solve the machining vibration control problem has become more urgent. This paper on turning aluminum rod tool of three to the vibration research, design the three kinds of test programs: (1) change the depth of the turning; (2) to change the spindle speed; (3) to change the feed rate of the three methods, through the use QLVC-ZSA1 type dynamic signal analyzer of turning aluminum rod tool to the frequency domain characteristics of the vibration. The research shows that: (1) when the turning depth is changed, the power spectral density of the three is relatively stable, and the X direction is the largest in the Z direction, and the Y direction is the smallest.. Turning depth of tools to the vibration effect is not obvious; (2) different feed speeds, x, y, Z three directions of power spectrum value increases with the increase of feed speed, turning feedrate is increased, an increase in the energy of the vibrating tool, the vibration of the tool and the workpiece become more violent; (3) in the test of three different spindle speed, speed 700r/min tool of three direction vibration are the most strongly.
