What is the difference between precise and imprecise assemblies in Teamcenter?

An imprecise product structure is automatically reconfigured when any user releases a part, creates a new part, or performs any other action that affects the view. Use precise assemblies to control the configuration of the structure closely. Introduce revision rules when users are familiar with the system.

What is precise and imprecise?

While “precision” is difficult to quantify in precise engineering and imprecise engineering implies “uncertainty”, both the engineering methods provide an interesting facet to the engineering design process and are critical for the overall product development at various stages and in version updates.

What is a precise assembly in Teamcenter?

The command File→Save Precise Assembly performs the save operation on the current working assembly such that the assembly structure and all of its subassemblies are saved in Teamcenter as Precise BVR. This product structure has the same precise revision as what is currently in the NX session.

What is the precise revision rule?

Precise; Any Status Loads precise components. If those are not found, then loads components that have any released status.

What is the precise and imprecise assembly?

Precise assembly is used when BOM is near to final stages and hence specific revisions of items are used to represent BOM. On the other hand imprecise assembly is used when BOM is at initial or development stage , because of which the whole item container is used to represnt parts in BOM.

What is a precise assembly?

About us. Precision Assembly, Inc. is an Electronic Manufacturing Service (EMS) company that provides printed circuit board assembly services (PCB, PCBA) to regional OEM companies.

What is variant rule in Teamcenter?

Teamcenter supports two types of variants: classic and modular. Classic variant configurations allow you to create options and allowed values for those options, such as door and the options small, medium, large, and extra wide. You then define a variant rule, such as door=large, color=blue, handle=standard.

What is Teamcenter effectivity?

Occurrence effectivity is typically used to track major changes in the evolution of a product. This is different from revision effectivity which is typically used to track smaller changes in a product. Occurrence effectivity is used to track the dates of effectivity for a part.

What is BOM view in Teamcenter?

Bill of materials (BOM) management capabilities in Teamcenter can help your customers know about their products and understand whether they consist of 10 parts managed with basic processes and tools, or more complex products containing millions of parts, requiring more advanced tools, flexibility and scalability.

How do you use variant rule in Teamcenter?

First, in Teamcenter you create basic variant data:

  1. Define options. Create an engine option on the item Car Model G with allowed values 1200 and 1600. You can later create other necessary options and allowed values.
  2. Add variant conditions. Specify a variant condition on each engine component to configure it appropriately.

What is structure manager in Teamcenter?

What is Structure Manager in Teamcenter? Ans:-Structure Manager allows TC user to create standard Product structure that can be configured to show the Product Structure. Structure manager functionality:- Manage Engineering Bill of materials. Configure Variants.

What is unit effectivity?

Unit effectivity is a method to control the validity of variations on an end item. You can use unit effectivity for pegging purposes, or to model exceptions from a standard end item so that you can make variations without having to define separate item codes.

What is preprecise / imprecise Teamcenter?

Precise / Imprecise Teamcenter has an concept of precise and imprecise structure. You can easily change an assembly from precise to imprecise or back again, if it has not been released (releasing the assembly is a change to the structure).

What is the difference between precisionprecise and imprecise Bom?

Precise BoM seems more suited for EBoM management, while imprecise appears to relate more to design and CAD structures.

How do I change the BoM view in Teamcenter after import?

By default, the BOM import will create a precise view in Teamcenter. However it can be changed to imprecise during the creation and update process in the mapping. To change the BOM view to imprecise, the following needs to be added to the function getCurrentTcBomInfo in the BOM import mapping to the part where the BOM header is initialized:

How to change the BoM view to imprecise?

To change the BOM view to imprecise, the following needs to be added to the function getCurrentTcBomInfo in the BOM import mapping to the part where the BOM header is initialized: # “1” for precise or “0” for imprecise. […] To change the whole BOM to imprecise, the BOM header line needs to be changed and not the BOM position lines.
