Original Abstract

The primary objective of this paper is to present a new method for measuring of geometric errors in the machine tool workspace in order to predict the accuracy of investigated workpiece. A general methodology for a three axis machine tool is described to map the volumetric errors and based on this map to evaluate the dimensional and geometric workpiece parameters. A measurement strategy uses a portable coordinate measurement system Laser Tracker and is intended principally for middle-size and large milling machines. For purposes of testing the strategy was applied on a small machine tool first. The relative discrepancies between the tool and the workpiece were estimated from the separate table and spindle measurements in contrast to application in large machine tools and other strategies. Based on the results and according to the required accuracy parameters, this method is used for locating the optimal workpiece position in the machine volume.
