DISCUS DFM focuses on characteristic management at an earlier stage in the product lifecycle when a manufacturing engineer is analyzing the detailed design of the part. In fact, by helping to define the applicable specs and annotations to include on the design, DISCUS DFM can actually assist with the definition of the Technical Data Package (TDP).

DISCUS DFM picks up where today’s leading CAD tools leave off by empowering the product team to consider the key considerations for manufacturing the part. An overview of the flow:
You start DISCUS by opening the native 3D CAD model in the model/drawing panel.
DISCUS will automatically review the model and its associated PMI and add the balloons to the model and the rows in the Bill of Characteristics.
You select the appropriate part family and likely list of manufacturing processes to consider for fabricating the part.
At this point, DISCUS DFM enables you to evaluate the part DFM by applying rules associated with the part’s features and characteristics versus the likely manufacturing processes.
The evaluation of the part against the integrated manufacturing knowledgebase results in a list of pertinent DFM constraints, recommended annotations/PMI for the part, and more.
When you're completed the analysis of the model, you can export the DFM data for review with the DFM engineer or the entire Integrated Product Team.

With DISCUS DFM, you consistently and correctly add the vital details to the design, giving you the ability to manufacture the new part right the first time. DISCUS DFM is the tool to improve the quality and productivity of your engineers.

  2. 2. Presentation Outline DISCUS DFM Overview – Detailed Design & Producibility – DISCUS DFM Operation & Outputs – Position in the Business Process – Typical Business Benefits – DISCUS Suite of Tools Software Demonstration – DISCUS Desktop – DISCUS DFM – DISCUS Knowledge Workbench2
  3. 3. Detailed Design Realities The creation of the detailed design documentation is still a laborious bottleneck for many companies Producibility (Design for Manufacturing) is frequently not addressed as part of the engineering design effort The proper completion of the detailed design really depends upon the manufacturing processes considered Manufacturing process knowledge is often not reused and actively applied during the detailed design The move towards a model-centric environment introduces new challenges & demands on engineering3

Detailed Design & Producibility Current Approach Create Share 3D Clarify Determine detailed model of design notes & design/ part intent annotation drawing Typical “Improved” Approach Create Share 3D Clarify Determine Perform detailed model of design notes & producibility design/ part intent annotation analysis drawing DISCUS DFM Approach This “bolt-on” approach adds labor & time to the overall business process Create Create Share 3D producible detailed model of detailed design in part design Master Spec Address producibility as part of creating a detailed design in less time & with less labor4
  5. 5. Key “Definers” for DISCUS DFM1. Rather than another simple checklist, help get detailed design completed quicker and with less design engineering labor2. Provide the Product Team with a way to easily discuss the detailed part characteristics and rapidly clarify design intent3. Enable the engineering knowledge to be captured by engineers, and provide transparency into the application of rules4. Enable the manufacturing engineer to be an instrumental part of getting the detailed design completed5. Support the principles of “multi-bird” engineering –- the activity of using a software tool that creates many useful outputs5
