Measurement of Synchronous Motion in Five-axis Machining Centers
TRANSACTIONS 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.

International 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 ...

Vision-Based Measurement of Two-Dimensional Positioning Errors of Machine Tools
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011 This paper presents vision-based measurement of two-dimensional positioning errors of machine tools. A pre-calibrated grid plate is used as an artefact. The position of a grid point is measured in an image captured by a charge coupled device (CCD) camera

Workpiece Setup Simulation based on Machinable Space of Five-axis Machining Centers
Procedia CIRP, 2014 AbstractAn actual machining center specification, e.g. the axes travel, the workpiece size allowance, etc., needs to be considered for constructing a machining process plan. In this paper, a machinable space of a five-axis machining center is proposed for simulating the workpiece setup.
