Laser accuracy measurement and calibration technique for machine toolsWANG Zheng-ping Optodyne Co., USA, CA70220, USAAbstract:To improve the volumetric accuracy of machine tools, it is necessary that squareness and straightness errors of machine tools are measured, compensated and calibrated. Traditional laser measurement method takes long time and high cost. ＂Body-diagonal＂ measurement presented by ISO and ASME, that is being used by the Boeing and others which gives accurate volumetric measurements for most equipment and featurs rapidness and low cost, but the error roots are not separated. This paper introduces a sequential-step diagonal measurement technique, which is invented by Optodyne Co. The measurement method can separate error roots and generate a compensation table that, in turn, can be used to calibrate the machine.[著者文摘]
