Cost Model Changes that don't Affect Configured Digital Factories

The following changes do not affect costings with Digital Factories that use earlier cost model versions. The changes are available only in the latest cost model version (CMV380).

  • Design Guidance (impacts only design guidance): In this release of aP Pro, the Machining, 2-Model Machining, and Stock Machining process groups now provide severity-based manufacturability design guidance for most processes. When you use the latest manufacturing process model versions (Machining CMV 380, 2-Model Machining CMV 130, Stock Machining CMV 220), design issues are now classified as Critical, Major, or Minor.

    The following categories of machining rules now provide prioritized design-for-manufacturability guidance:

    • Access and Setup Constraints

      Tool accessibility and setup feasibility issues now supply severity thresholds.

    • Obstruction and Geometry Detection

      Detection of geometric obstructions and interfering features improves the reliability of manufacturability assessments.

    • Ratio and Tooling Constraints

      Length-to-diameter ratios, depth constraints, and other tooling limitations have been aligned to severity-based classifications.

    • Hole and Turning-Specific Improvements

      Hole-making and turning operations have been updated with refined rule logic and severity classification to better reflect real machining constraints and best practices.

    The latest cost model also reduces false positives for the issue Side Milling L/D Ratio Exceeded.

    In Machining, a small number of rules are not yet migrated to the severity-based framework. AAs a result, a very small selection of issues may appear as Unclassified. Additional rule conversions and enhancements are planned for upcoming releases.

    In Stock Machining, six design guidance issues related to selecting alternate (smaller) stock sizes are displayed as Unclassified in this release, but will be categorized as cost-driving issues in a future release.
