An ISO 2768-mK mark means the dimension information for which the tolerances are not specified will be followed according to the m and K class. m class is specified in ISO 2768-1 and K class is specified in ISO 2768-2, which including H, K, and L tolerance levels.
ISO 2768 Part 1 is intended to simplify drawing indications and it specifies general tolerances for linear and angular dimensions without individual tolerance indications in four tolerance classes. It applies to the dimensions of parts that are produced by metal removal or parts that are formed with sheet metal fabrication.
Including ISO 2768 specifications in your manufacturing process ensure adequate control of every element of geometry and size of a part. With this standard, there will be no need to leave anything to judgment. Using general tolerances for geometry and size allows you to avoid writing tolerances for every feature and dimension.
The following tolerance tables correspond to the different precision levels. This part of the international tolerance standards has three tables with respect to ideas involving general dimensional tolerances.
This part is intended to simplify drawing indications and specifies general tolerances in three tolerance classes. It mainly applies to features which are produced by removal of material. It contains tour tables and an informative annex A with regard to concepts behind general tolerancing of dimensions, as well as an informative annex B with further information.
ISO 2768 provides general standard metric tolerances (mm) for linear and angular dimensions without individual tolerance indications in four tolerance classes. It is an international manufacturing standard that can not only help to determine standard machining tolerances, but also minimize inconsistencies while accounting for manufacturing costs as well.
It is not possible to define engineering tolerances against each dimension. Therefore engineers define general tolerances in engineering drawings to define the variation. ISO 2768 standard defines general tolerance for:
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. 153554b96e
