A simple experiment is provided to show that the vibration frequency in cutting chatter mainly depends on the model natural frequency of the cutting system of the machine tools.The frictional self-excited vibration is the important cause of the cutting chatter.Get Price
Thin-walled workpieces are widely used in the aerospace manufacturing industry in order to reduce the weight of structure and improve working efficiency.However, vibration is easy to occur in machining of thin-walled structures due to its low stiffness.Machining vibration will result in lower machining accuracy as well as machining efficiency.
Used technique in condition based maintenance and rely a lot on instrumentation machine vibrations stack a lot of information about the condition of a machine.Measurement and analysis of the vibration response gives a lot of information with relevance to fault conditions in different types of machines khwaja, gupta, kumar, 2010.
It is difficult to detect the mill loadml efficiently in the ore milling process of a ball mill and the mill is often underloading,thus causing the difficulty in implementing the optimal control with energy saving and cost reduction.To solve the problems,how the vibration of.
