The study will develop the important research domain in the high efficiency grinding which has great potentialities, considering that the increase of heat transfer efficiency means an synchronous increase of the limit material removal rate under the condition of grinding unburn, therefore the further perfection of this study will not only increase the available material removal rate to a new level, but also solve the workpiece burn problem of the difficult-to-machining materials in the high efficiency grinding, which has great technical and economical significance

本项研究可望开拓高效磨削的极富潜力的重要研究方向，考虑到换热效率的提高本身也就意味着磨削时不发生烧伤的材料极限去除率的同步提高，因而进一步完善此项研究不仅可望将现有高效深切磨削的材料去除率提高到一个新水平，而且将有效解决难加工材料的高效磨削问题，其技术经济意义十分重大。

The experimental results show that wavelet transform method may filter effectively the background noise, furthermore, may accurately locate the fault point in time and frequency domain.
