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

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 ...

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.
