Abstract

To rapidly measure and trace the simultaneous rotary-translational(R-T)axes motion error of multi-axes numerical control(NC)machine tool

a kind of motion error estimation method based on built-in sensor

such as grid scale and motor encoder

is proposed. The sensorless information of multi-axis NC machine tool is obtained via the redevelopment of the different NC system. According to the characteristics of simultaneous R-T axes motion

a virtual bar with some functions of ballbar is constructed. And the virtual bar-based test path of circular error test through collaborative motion of a rotary axis and two translational axes is scheduled

which is implemented to measure the simultaneous R-T axes motion error of multi-axis NC machine tool. Then

the coupling and decoupling mathematical models of the motion error is established based on the test principle of the virtual bar

respectively. To localize the error sources conveniently

some typical spatial error charts and the wavelet spectrum analysis technology are introduced. The experimental results show the practicability and effectiveness of the proposed method for measuring the motion error.
