Dynamic measuring system of mechanical transmission link in laser cutting machine of optical disks for servo grooves and preformatted information

摘要

Abstract: By combining the practical mechanical transmission system with the laser cutting machine of optical disks, a high precision dynamic measurement system of round to long mechanical transmission link is designed. The working principle and system errors are described. Our experiments have proved that the measurement system is completely competent for the measuring task. The special computer interface board and the practical computer software are designed with advantages of fast data collecting and high processing ability. The mechanical transmission link error can be obtained after processing the data. !2
