Electrical Manufacturing Engineering

Once the 3D Design of Wire Harnesses in the context of their complete product is finalized, the next step is the Wire Harness Manufacturing. 3DEXPERIENCE platform provides an application enabling the automatic generation of manufacturing documents, including annotated drawings, all needed reports and on scale formboards.

Dedicated automatic processes covering all use cases:

Documentation for subcontractors

Documentation process addresses companies who work with subcontractors for the harness manufacturing step and who need to provide them all manufacturing information.

• Automatic generation of annotated and scaled manufacturing drawing to be transmitted to subcontractors, including reports according to company standards

• Automatic generation of harness dimensions in the drawing documents but manual modification is still available

Formboard for harness manufacturers (harness manufacturing on jig board)

Formboard process addresses customers who manufacture their own harnesses.

• Automatic formboard generation: harness flattening and alignment on jig boards

• Automatic on scale formboard drawing generation which can be sticked on the board

• Harness flattening taking into account harness backbone definition, potential loops to open and formboard tables potentially already installed

• Automatic harness backbone path computation and display in pink in 3D

• Possibility to add special flatten behavior for some branches to comply with manufacturing constraints and to respect curvature/twist on very rigid segments

 3D Manufacturing for rigid harness manufacturers

The final process is the 3D Manufacturing, addressing customers manufacturing very rigid harnesses. The process generates a torsion-free layout in which the tangency at branch junctions is kept.

• Automatic generation of harness with limited torsion

• Partial flattening for complex rigid harnesses

• Creation of 3D manufacturing information taking into account the curvature and allowed torsion of the bundle segments

• Critical functionality for aero engine harnesses

Electrical Manufacturing automatic processes all offer:

• A robust validation of the data to process & new checks performed in the behind scene

• Information about the processed data : dashboarding with advanced reports for each step and cross-highlight capability

• A high-level of user interface targeting to minimize user interactions but manual modification is still available

• Better integration in data setup and preferences minimizing preparation steps for users and allowing centralized administration of company rules

  • Sheet template and GVS file for documentation process

Backbone identification criteria, board dimensions and offset from plane for formboard process
