| Abstract: | The laser x-y coordinate standard equipment is introduced, combined with the point-supported platform technology, aiming at the deformation problem of micro-glass platform , the method of light-weighting and changing point-supporting style has been used to reduce influencing of deformation on the measurement. Using CATIA software to model and do finite element analysis (FEA) for micro-glass platform, by statics analysis, the supporting method of platform is determined. |
