Algemeen toleranties volgens DIN ISO 2768-2

by on 23. Mar, 2010 in Library, toleranties

(in het engels) 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. If smaller tolerances are needed or bigger are more economical these tolerances should be mentioned directly according to ISO 1101. General tolerances for form and position should be used while the tolerance principle according. to ISO 8015 is valid and while this is mentioned in the drawing. This tolerance principles says that no opposite relation between measure, form and position tolerance exists (principle of superposition).

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, coaxiality, position and total movement.

Algemeen toleranties volgens DIN ISO 2768-1

by on 22. Mar, 2010 in Library, toleranties

(In het engels) General tolerances for linear measures and level squares with four tolerance classes are useful for simplifying drawings. By choosing the tolerance class precision levels common in workshops should be taken into account. If smaller tolerances are needed or bigger ones are more economical, then these tolerances are indicated next to the nominal size.

v (very coarce grob)		 - ± 0,5 ± 1 ± 1,5 ± 2,5 ± 4 ± 6 ± 8

For nominal sizes below 0,5 mm the limit measures are to be indicated directly at the nominal measure.

For nominal sizes below 0,5 mm the limit measures are to be indicated directly at the nominal measure. If general tolerances according to ISO 2768-1 are valid, the following has to be inserted in the title box, i.e. for tolerance class medium ISO 2768 – m or general tolerance ISO 2768 – m

For new designs only the general tolerance according to DIN ISO 2768-1 should be valid. The limit measurements of the tolerance classes m and f of DIN ISO 2768-1 are identic with those of DIN 7168-1.
