The cutting mechanism in different position on the cutting edge of flat drill is researched in low-frequency vibration drilling. Experiments are carried on to measure the temperature on the bottom and locate the highest temperature position. And also, the variation of temperature resulting from different amplitudes is analyzed. Experiment results show that low-frequency vibration drilling can reduce the highest temperature relative to normal drilling and temperature reduces by 37% with the 0.18mm amplitude.

Exit Burr

Based on analyzing the mechanism of forming exit burr in drilling, the paper researches the process of forming exit burr in low frequency vibration drilling. The calculate formula of exit burr is achieved after calculate the force of axial and other forces in low frequency vibration drilling, which is also proved the reliability by the experiment. The parameters optimization method is available in order to reduce or mitigate the low frequency axial vibration drilling. It is lay a solid foundation for selecting the reasonable parameters of vibrating drilling process in the theory.

The lateral line organs of the sea eel consist of canal and pit organs which are different in function. The former is a low frequency vibration detector whereas the latter functions as an ion receptor as well as a mechano receptor.The fine structure of the sensory epithelia of both organs were studied by means of ordinary transmission electron microscope, high voltage electron microscope and of surface scanning electron microscope.The sensory cells of the canal organ are polarized in front-caudal direction and those of the pit organ are polarized in dorso-ventral direction. The sensory epithelia of both organs have thinner surface coats compared to the surrounding ordinary epithelial cells, which have very thick fuzzy coatings on the apical surface.
