Analysis of Generating Motion for Five-Axis machining Centers.
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
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.

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 ...
