Study of Laser Non-contact Measuring Method of Circle Path Applied to Precision Analysis of 3-azes CNC Machine Tools

Laser non-contact precision measuring method of CNC machine tools under the high feed rate condition was put forward. The method combines the laser interferometer with the measurement principle of the double bali bar (DBB), and can measure the machine tool precision under the high feed rate condition. Two laser interferometers used as measuring the displacements and feed rate data along circular interpolation motion individually measured three group data in the XY, YZ and XZ work planes, and the space errors of the CNC can be acquired through solving the special mathematic model based on the measurement principle of DBB.
