Configuration Optimisation of Laser Tracker Location on Verification Process. [PDF]
Materials (Basel), 2020 Machine tools are verified and compensated periodically to improve accuracy. The main aim of machine tool verification is to reduce the influence of quasi-static errors, especially geometric errors. As these errors show systematic behavior, their influence can be compensated. However, verification itself is influenced by random uncertainty sources that

Flatness Measurement of Large Flat With Two-Station Laser Trackers
International Journal of Optomechatronics, 2018 We present a novel method to accurately measure the flatness of a large flat. The method can be seen as a task-specific error correction of the laser tracker. Laser trackers are positioned at two specific measuring stations and measure the coordinates of
