Identification Method of Geometric Deviations for Multi-Tasking Machine Tools Considering the Squareness of Translational Axes

open access: yesApplied Sciences, 2020
Some methods to identify geometric deviations of five-axis machining centers have been proposed until now. However, they are not suitable for multi-tasking machine tools because of the different configuration and the mutual motion of the axes. Therefore,

Analysis of Generating Motion for Five-Axis machining Centers.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1993
This paper deals with the theoretical investigation of the arrangement of slideways for five-axis machining centers. There is a considerable number of combinations with respect to the five-axis slideways. However, a critical assessment of the possible combinations of slideways has not been performed so far.

Measurement of Synchronous Motion in Five-axis Machining Centers

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2006
This paper describes a newly proposed method for evaluating the synchronous inaccuracy of the translational and rotational axes in five-axis controlled machining centers. The circular motion of which shape is easy to evaluate is adopted for measuring the trajectory described by the axes in the proposed method.

Geometric Error Compensation of Five-Axis Machining Centers Based on On-Machine Workpiece Measurement

open access: yesInternational Journal of Automation Technology, 2018
This study proposes an identification and compensation method for the geometric errors of the rotary axes in five-axis machining centers, based on the on-machine measurement results of the machined workpiece. Geometric errors can be identified from the shape geometry of the workpiece machined by five-axis motions because the influence of the errors ...
