For task-specific coordinate metrology, it is necessary to associate with task-specific parameters an estimate of their uncertainty at a specified level of confidence. In recent years, various sources of uncertainty for laser trackers themselves have

Due to lack of considering the non-geometric process parameters during assembly process planning, it is difficult to control the production cycle, cost, quality, reliability, stability and consistency of high-performance mechanical systems. To change

The present studies of assembly accuracy predicting for complex products are mainly oriented to the early design stage. The final product assembly accuracy is computed using a variation propagation model, which is constructed based on design toleranc
