Single-Minute Exchange of Die (SMED)
Setup reduction supported by real execution data, dimensional validation and QIF (ISO 23952) integration
IVR SMED structures setup activities with measurable timestamps and links each changeover to dimensional results automatically collected from IMTE — Inspection Measuring and Test Equipment. First-piece approval is validated through QIF-structured characteristics and SPC behavior, ensuring that setup reduction does not compromise dimensional stability or traceability.
Controlled and measurable changeovers
- Timestamped setup phases linked to production orders
- First-piece dimensional validation from IMTE
- QIF-based characteristic approval criteria
- SPC stability verification after changeover
- Integrated CAD + QIF + DMIS digital thread
Structured setup activities with measurable evidence
IVR SMED decomposes setup operations into internal and external activities, each recorded with precise timestamps and linked to specific production orders in MES.
This structured approach enables objective analysis of changeover duration and variability, supporting continuous improvement initiatives grounded in real execution data.
Setup time becomes a measurable and traceable process parameter.
Dimensional validation of first-piece approval
After each changeover, first-piece inspection results are automatically collected from IMTE — Inspection Measuring and Test Equipment and structured according to QIF (ISO 23952).
Dimensional characteristics defined in CAD remain linked to their tolerances and actual values, ensuring that approval decisions are based on objective measurement data.
- Characteristic-by-characteristic validation
- Nominal, tolerance and actual value comparison
- Traceable approval records per setup event
SPC stability after changeover
IVR SMED integrates with SPC to monitor statistical behavior immediately after setup completion. Control charts and Cp/Cpk indices are associated with the specific changeover event.
This ensures that reduced setup time does not introduce process instability or dimensional drift during initial production cycles.
Setup optimization is validated by statistical evidence.
Correlation with OEE and production performance
Changeover duration and stability are correlated with OEE results, enabling analysis of how setup improvements impact availability and quality components.
By linking dimensional performance with execution metrics, IVR SMED provides a technically grounded view of setup efficiency and its real production effects.
- Setup impact on availability losses
- Quality factor variation after changeover
- Order-level performance comparison
Audit-ready setup documentation
All setup phases, dimensional validations and statistical evaluations are stored as structured, retrievable records.
The continuous digital thread — CAD → QIF → DMIS → IMTE → MES → SMED — preserves alignment between engineering definition, measurement evidence and setup execution.
Changeover becomes a documented, traceable and technically defensible process.
