Year: 1997
Type: article
Abstract: At present, most CAD systems deal only with operations related to geometric forms, omitting operations related to accuracy information such as tolerances and roughness. We expressed toleranced features and their inter-relations in terms of the features based on the ISO including general tolerances. Specified tolerances of features are expressed by limits of degree of freedom, and we defined a method using matrices to indicate the behavior of a feature. We also defined constraint equation (representing tolerance conditions such as MMP and envelope requirement) to determine the elements of each matrix.
