【Abstract】 Tolerance conformance test between dimension tolerance and geometric tolerances is an indispensable part of computer-aided tolerancing design.According to the tolerance rules of ER,MMC and LMR of national standards,tolerance conformance test of prisms is carried out.Its results are some mathematically equivalent formulas.also,an example is used to verify the practicability of these methods.So the thesis provides an executable method for the conformance evaluation of computer-aided tolerancing design.更多还原
