To achieve high quality and productivity, it is important to know what is the maximum feed rate while meeting the required part accuracy. Laser interferometers and telescoping ballbars have been used for the positioning and circular contouring measurement. However, a conventional laser is limited by the line-of-sight, and cannot tolerate large lateral deviations. A telescoping ballbar is limite...

Purpose – The purpose of this work is to investigate the use of a laser tracker, a laser interferometer system and a telescopic ballbar for assessing the positioning performance of a six-axis industrial serial robot. The paper also aims to illustrate the limitations of these three metrology instruments for the assessment of robot positioning performance and to demonstrate the inadequacy of simp...

In order to overcome the influence of particularity hybrid machine tool on error compensation, this paper presents an compensation strategy based NC model. The X-Y table and spindle deflection accuracy are tested by ballbar in paper. Based real -virtual axis structure,the detection is implemented.The data before after analyzed compared. It confirmed that has a significant effect improvement mot...

Present work deals with the accuracy of manufacturing machines and the possibility of regular diagnostic of machining centers in order to improve the quality and productivity of machining process of a CNC MCV-400 machine usingLaser calibration and Ballbar tests with the help of Renishaw equipment.The accuracy of machine tools is a critical factor that affects the quality of manufactured product...
