4.2.461 Same_time_machining_relationship

A Same_time_machining_relationship is a relationship between two Item_instance objects that specifies that those two objects shall be manufactured together within the same Process_operation_occurrence.

EXAMPLE Figure 65 shows an example for this case.

A Same_time_machining_relationship is a type of Item_instance_relationship.

The data associated with a Same_time_machining_relationship are the following:

4.2.461.1 description

The description specifies additional information about the Same_time_machining_relationship.

See same_time_machining_relationship to multi_language_string for the application assertion.

The description need not be specified for a particular Same_time_machining_relationship.

If present, there shall be exactly one object that defines the description for a Same_time_machining_relationship.

4.2.461.2 placement

The placement specifies the geometrical Transformation between the local coordinate system of the related Item_instance with respect to the local coordinate system of the relating Item_instance.

NOTE The transformation is needed to position the related Item_instance with respect to the relating Item_instance for the same time machining process.

In the case where the placement is realized by a Template_instance the scale factor of that Template_instance shall be omitted or set to 1.

See same_time_machining_relationship to geometric_model_relationship_with_transformation and same_time_machining_relationship to template_instance for the application assertions.

The placement need not be specified for a particular Same_time_machining_relationship.

If present, there shall be exactly one object that defines the placement for a Same_time_machining_relationship.
