The objective of this standard is to provide functionally and technically appropriate tolerances for use at the beginning of the development or manufacturing process. Therefore, the sub-committee for pressed components has defined the general tolerances specified in this standard together with guidelines for their documentation and representation in manufacturing documents. In the case of CAD-defined components, the coordinate values are based on the datum, and the tolerance standards currently used are unsuitable. Manufacturer, necessitate expensive operations such as recalibration or tool modification, or entail failure to comply with launching schedules together with the associated costs. This in turn might cause disagreement with the Possible consequences are that the components in question do not perform their functions reliably and are unsuitable for joining purposes. The design of the tools is unfavorable. The design of the pressed components is unfavorable. No reference system/no reference planes have been specified, giving rise to different These problems have any of the following causes. tolerances being exceeded) which might consequently increase the costs involved.
