COMPUTER AIDED ASSIGNING OF TOLERANCES AND SOLVING THE CHAINS OF DIMENSIONS

摘要

The paper presents some considerations about assigning tolerances and computing the dimensions chains using a CAD Program developed in AutoCAD~R with AutoLISP~R. The presented methods to assign tolerances and solve the direct and the inverse problems of dimension chains are powerful design accessaries that can increase the design cadence and provide the usual information needed without consulting specialized, classical printed documents. The assignation of. iterances is in total concordance with the used ISO standards and the results are verified through several moths of use.
