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 (CMV390).

  • Design Guidance (impacts only design guidance):This release completes the implementation of the prioritized design guidance framework for the Machining process group. The release finalizes the alignment of existing Machining advice rules with the Critical, Major, and Minor severity classification system first introduced in aP Pro 2026 R1 and version CMV 380.

    • Updated rule categories in version CMV 390 of the Machining manufacturing process model include:

    • Excessive Part Aspect Ratio: Flags turned parts where the length-to-diameter ratio creates a manufacturability risk.

    • Non-Standard Countersink: Identifies countersink geometry that does not conform to standard tooling angles, requiring custom tooling and increasing cost and lead time.
    • Non-Standard Hole Bottom: Identifies drill point angles that require non-standard tooling.
    • Tolerance Rules: Tolerance advice rules in Machining are now correctly classified by impact: tolerances that are infeasible are raised as Major manufacturability issues; tolerances resolvable through finish machining operations are classified as Cost Drivers.
    • Insufficient Internal Radius (Turned Parts): Reclassified from a Cost Driver to a Minor Manufacturability issue, better reflecting the genuine design constraint that small internal radii impose on turning operations.

    • Excessive Tool Reach and Restricted Tool Holder Access are now classified by severity.

      Note:

      Restricted Tool Holder Access has been switched off in starting point Digital Factories but can be turned on by setting the rule value to true in the adviceRules lookup table (see Enable and Disable Design Guidance Rules).
