CNC Machine tool Vibration Test

Abstract Since entering the 21st century, with China as the representative of the  new world economy high speed development, in these economies, computer technology, electronic technology, numerical control technology development is rapid. CNC machine tools is the key equipment of modern manufacturing industry, the yield and technical level of a state of NC machine tools in some degree on behalf  of the country's manufacturing sector and the level of competitiveness. Therefore, to reduce the vibration machine tool and improve the efficiency in the use of machine tool. It has very high practicability

Analysis of the vibration signal of the NC machine tool in this paper, the main research, so the main purpose of this paper is to study the induction is as follows: the analysis of CNC machine tool vibration and the purpose and significance, research vibration test at home and abroad is summarized, and the vibration test of the basic principle and vibration test system of basic composition, design test plan and test, test data acquisition, test data and data processing, analysis of test data and obtain the corresponding conclusion. Expounds the fault reason and fault signal analysis method. Needle log control machine as a result of the failure of CNC machine tools, put forward the effective solutions, try to avoid vibration To produce and reduce the damage to the NC machine tools.
