Beschreibung

The clamping piece of a clamping unit is specified, which is required to transmit clamping forces to the workpiece via an eccentric lever. Among other things, fits are necessary, as well as a functional geometric description of the clamping area to ensure that it does not leave for instance pressure marks on the workpiece. Areas that are not functionally relevant should be defined using general geometric tolerances.

Difficulty Level: Suitability 1-2

 

Description of the level of difficulty (suitability for the user):

1 – The user has basic knowledge but has not yet used ISO GPS frequently in practice and takes first steps.

2 – The user has basic knowledge but is not proof about using ISO GPS and would like to gain more general confidence.
More „special“ or complex modifiers (these are usually listed in the example description) are applied selectively.

3 – The user has sufficient knowledge, can already use frequently used ISO GPS tools without difficulty,
and would like to deepen knowledge selectively based on typical functional descriptions,
which is usually also product-specific (e.g., snapping features (latching hooks) on a plastic injection-molded part, special demand hole patterns, i.e. multi-level patterns etc.)
used in the example (i.e., listed in the description) (e.g., direction only or certain combinations of dimensional tolerancing, as well as SIM or similar modifications).

4 – The user has extensive knowledge, has been working with ISO GPS for a long time,
and would like to learn about very specific applications or modification operations, which usually describe more complex functional requirements and products.
This requires, for example, situation features, reference elements, filter information, association modifiers etc.

used specification modifiers

in addition to the commonly used tools (profile, position, datums, etc.), the following modifiers were used:

  • Envelope requirement (Taylor principle)
  • GX modifier - Maximum inscribed feature
  • LP modifier - Local point size
  • CT - Common toleranced feature of size
  • CZ - Combined zone (Common zone)
  • >< - For orientation constraint only (Direction only) modifier
  • Intersection plane indicator

Standards

The following standards are helpful or have been used

ISO 129-1 Technical product documentation (TPD) - Presentation of dimensions and tolerances
ISO 1101 Geometrical tolerancing - Tolerances of form, orientation, location and run-out
ISO 14405-1 Dimensional tolerancing - Linear sizes
ISO 5459 Geometrical tolerancing - Datums and datum systems
ISO 22081 Geometrical tolerancing - General geometrical specifications

Additional information

This is not a complete specification. For example, the following topics are not covered:

  • Edges of undefined shape (ISO 13715)
  • Indication of surface texture (ISO 1302 bzw. ISO 21920)
  • Data fields in title blocks and document headers (ISO 7200)
