Quasi-static kinematics model for motion errors of closed hydrostatic guideways in ultra-precision machining

Chenchun Shi et al.

Summary: The paper presents a novel analysis model for motion errors in closed hydrostatic guideways using kinematic theory, which shows consistently good agreement with experimental data from a large ultra-precision grinding machine. It is found that motion accuracy is more sensitive to the profile error of the guide rail bearing the external load in the closed hydrostatic guideway.

Geometric error identification for machine tools using a novel 1D probe system

Jianxiong Chen et al.

Summary: A novel system using a one-dimensional probe and ball array is proposed for fast estimation of geometric error of a linear axis. By establishing an identification model and correction method, accurate evaluation of positioning error and straightness error of the linear axis is achieved. The results demonstrate the validity and accuracy of the proposed method in measuring geometric errors.

A method for noise attenuation of straightness measurement based on laser collimation

Wenzheng Liu et al.

Summary: A method for noise attenuation of straightness measurement based on laser collimation was proposed to address the issue of atmospheric turbulence interference. The turbulence shield effectively reduced the impact of atmospheric turbulence on the measurement results, leading to improved accuracy and stability of the straightness measurement. Experimental results showed a significant decrease in standard deviations of straightness noise, with the effectiveness of the turbulence shield validated through simulations.
