Abstract Because of uneven temperature distributions, machine tools can generate thermal errors, which significantly contribute to machining errors. Previous research has shown that volumetric errors be directly measured using optical methods or indirectly calculated error mapping methods. However, these are limited restricted by specific working conditions. Therefore, our study focused on developing a novel R-test measurement system for realising accurate measurements. The consists...
Geometric errors of machine tools are one the main contributors for machining inaccuracies. A multi-step error measurement and compensation method is proposed in this paper to investigate effects different geometric on volumetric errors. The kinematic chain built using multi-body system theory (MBS) homogenous transformation matrices first. Then, original without any compensations measured deviations tool tip caused by calculated. Furthermore, various strategies considering diverse carried...
This paper studied the mechanism of assembly deformation guideway and proposed an process to improve precision guideway. Firstly, is based on theory statically indeterminate beam. Secondly, experiment carried out a test-bed, result consistent with theoretical analysis. Finally, technology effectiveness proposedtechnology validated experimentally.
