Software, and simulated by Monte Carlo method. The simulation results are conducted by descriptive statistics. Two "drop-in" assembly design lens groups were studied to calculate the stack-up element tilt and decenter within a cell and the resultant deviations of the optical axes away from the mechanical datum axis. The results indicate that the opto-mechanical tolerance model can analyze the critical to quality parameters of a lens system. As a result, the performance of the lens system can be anticipated by the opto-mechanical tolerance model before mass production.

The law how these factors influence the joint"s property was pointed out. A formula about the relationship between extrusion times and contamination remainder was founded. Main reason to bimetal"s inharmonic deformation was the difference of their mechanical property. Thereby, the empirical formula showing the relation between metal combination"s mechanical property and quality of joint was constructed. Integrated influence of extrusion times and metal"s mechanical property to quality of cold pressure welding joint was discussed.
