A 200 mm long surface under class k for flatness allows up to 0.4 mm deviation (0.2 mm per 100 mm).
The ISO 2768-mk standard provides several benefits, including: iso 2768-mk pdf
This refers to ISO 2768-2 , which covers geometrical tolerances such as flatness, straightness, and perpendicularity. The "K" class represents a medium level of geometric control. ISO 2768-1: Linear & Angular Tolerances ("m" Class) A 200 mm long surface under class k
By understanding and applying the guidelines outlined in the ISO 2768-MK PDF, professionals can ensure that their parts and assemblies meet required specifications, improving overall quality and efficiency in the manufacturing process. ISO 2768-1: Linear & Angular Tolerances ("m" Class)
