With the progress of modern science and technique, the manufacturing industry becomes more and more complex and
intelligent. It is the challenge for stable, safe running and economical efficiency of machining equipment such as
high-quality numerical control because of its complex structure and integrated functions, and the potential faults are easy
to happen. How to ensure the equipment runs stably and reliably becomes the key problem to improve the machining
precision and efficiency. In order to prolong the average no-fault time, stable running and machining precision of
numerical control, it is very important to make relative test and research on acquisition of data of numerical control
sample and establishment of sample database. Take high-end CNC Machine Tool for example, the research on test
techniques for data acquisition of sample of typical functional parts in CNC Machine Tool will be made and test
condition will be set up; the test methods for sample acquisition on running state monitoring and fault forewarning and
diagnosis of numerical control is determined; the test platform for typical functional parts of numerical control is
established; the sample database is designed and the sample base and knowledge mode is made. The test and research
provide key test techniques to disclosure dynamic performance of fault and precision degeneration, and analyze the
impact factors to fault.
