Research Status and Trend of Geometrical Error Measurement of CNC Machine Tools
CNC machine tools as the foundation of modern manufacturing industry
is a vital sign for the evaluation of the national whole industry. With the development of science and technology
the requirement of machining accuracy is getting higher and higher. The accuracy and precision stability of CNC machine tool is facing serious challenging. Therefore
how to measure the error of machine tool quickly and accurately is one of the research hot points. The main measuring method are reviewed from the perspectives of measuring instrument and measuring strategy
which include the laser interferometer
laser tracer
laser volumetric error measurement
double ball bar
cross grid encoder
R-test
standard artefact measurement. Also the research status of thermal error and cutting force induced error are briefly reviewed
and the main challenging of the error measurement technology and the next development trend are analyzed. Also some proposals for our unique techniques of the error measurement are given.
