General Tolerance on Machined Parts
|
This this the tolerance table intended to simplify drawing indications and specifies general tolerances in four tolerance classes. It applies to the dimensions of work pieces that are produced by metal removal or are formed from sheet metal. It contains three tables and an informative annex with regard to concepts behind general tolerancing of dimensions. General tolerances for linear measures according to DIN ISO 2768-1 Table one - Permissible deviations for linear dimensions except for broken edges (external radius and chamfer heights)
Table two - Permissible deviations for broken edges (external radius and chamfer heights)
Table three - Permissible deviations for angular dimensions
General tolerances for form and position DIN ISO 2768-2 is for simplifying drawing and fixes general tolerances in three tolerance classes for form and position. By choosing a special tolerance class exactly the precision level common in workshops should be taken into account. General tolerances for straightness and evenness in mm

Note: General tolerances for form and position are valid for form elements for which form and position tolerances are not indicated individually. They are applicable for all characteristics of the form elements accept cylinders, profiles of any line or surfaces, inclines, coaxially, position and total movement.
