An external system can exchange joint data using the methods defined in section 7.6.

Selection of joint can be done using the method defined in section 7.6.5 which selects the joining process needed to perform the joining operation.

Use Cases Solution Details

In the previous sections, there are two use cases illustrating two problems. The models described in section H.2, are intended to solve the defined problems based on the following explanation.

Use Case 1 Explanation: As joint model contains a relation between a joint identity and a joining program, it allows separation of the following responsibilities:

  • Which joints should be addressed in a specific station in the factory.
  • How such joining operations should be performed.

This results in independent management of changes on the production line which helps in handling the higher number of product variations.


  • Multiple joints can use the same joining program.
  • A joining system can assign all the possible joints to corresponding joining programs.

Use Case 2 Explanation: As the joint design model contains the physical properties of a joint, the system has access to more data to perform analytics which can be used to simplify and improve the production process.
