Slider control cam

29,00 

Practical example of a linearly guided slider with a cam profile. Covers the function-oriented datum specification using restricted areas, the precise tolerancing of the cam profile according to the principle of „as accurate as necessary“, as well as the clear specification of thread depth, thread engagement depth, and tap drill depth.

When purchasing this product, you will receive a video (step-by-step guide) and a PDF file.

Beschreibung

A slide is specified that is driven linearly in a guide and transmits a stroke to a plunger via a control cam.

In addition to a functional datum system that is specified using restricted areas, the control cam (control curve) must be described very precisely in order to meet the well-known (but rarely realized in practice) requirement of “as precisely as necessary”. This is the only way to ensure a later cost-effective production.

A thread should also be described unambiguos and in a practice-oriented (screw depth, core hole depth)

Difficulty Level: Suitability 2-3

 

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)
  • Restrictive specifications
  • >< – 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 1660       Geometrical tolerancing – Profile tolerancing

  • ISO 14405-1: Dimensional tolerancing – Linear sizes

  • ISO 14405-2 Dimensional tolerancing – Dimensions other than linear or angular sizes

  • ISO 5459       Geometrical tolerancing – Datums and datum systems
  • ISO 22081     Geometrical tolerancing – General geometrical specifications and general size 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)
