Machining processes for technical products inevitably cause minor dimensional deviations from the target state.
Manufacturing tolerances indicate the range of permissible deviation. If the actual dimensions of the products are within this range, no regulatory intervention in the ongoing process is necessary.
Manufacturing tolerances ensure that individual components in a technical system can be replaced without impairing the function of the overall system. This means that the use of manufacturing tolerances is the basis for stable series production.
#1 Definition of manufacturing tolerances
Manufacturing tolerances can relate to various dimensions and properties. They indicate the deviation of the actual value from the specified standard at which the technical system is still functional.
#2 Significance of manufacturing tolerances
Manufacturing tolerances relate to lengths and angles, but also to geometric shapes such as roundness and straightness. They are also used to specify the positioning of components in relation to each other (such as parallelism).
Instead of referring to generally standardized tolerances, specific tolerances can also be specified in a technical drawing.
