Abstract

Compared to the function-oriented tolerancing rules for micro monolithic components, the lack of specific tolerancing rules for micro non-monolithic ones results in difficulties in bulk production and quality assurance. In order to regulate micro non-monolithic components in micro/meso-scale, a mathematical model of power function is adopted to forecast the tolerance values of nominal sizes in 10~10,000 microns by the linearized regression analysis. The goodness-of-fit qualifies the regression with the power function model and the forecasting results are reasonable in the view of relative accuracy. It is hoped that the improved numerical value table of tolerance can provide some beneficial proposals for the establishment of new tolerancing rules for micro non-monolithic components in micro/meso-scale.
