Research and Development of a CNC Machine Tool Dynamic Characteristics Test and Analysis System

Abstract:

A dynamic characteristics test and analysis system for CNC machine tool is developed based on C++/Qt platform and NI-DAQmx data acquisition driver. The function modules include hammer experiment, signal continuous acquisition, spectral analysis, frequency response function analysis and signal coherence analysis, etc. The analysis results provide the basis of dynamics characteristics simulation and cutting parameters optimization. The system can be also used to analysis the vibration of the cutting process. Spectrum analysis modules help to assess the cutting stability and diagnose problems. Experiments show that the system has good accuracy and efficiency while the size and price are decreased compare with traditional equipment.
