Overall Equipment Effectiveness (OEE)
OEE calculated with real dimensional quality data, production traceability and QIF (ISO 23952) integration
IVR OEE correlates availability, performance and quality with real inspection results automatically collected from IMTE — Inspection Measuring and Test Equipment, without manual data entry. Quality losses are calculated from structured QIF characteristics and SPC behavior, linking equipment effectiveness directly to measurable dimensional evidence.
Effectiveness with objective quality input
- Automatic quality index from IMTE dimensional results
- OEE quality factor based on QIF structured characteristics
- Real-time linkage between SPC deviations and equipment losses
- Traceability by machine, shift, operator and order
- Integrated CAD + QIF + DMIS measurement flow
Quality factor derived from dimensional evidence
In IVR OEE, the quality component is not estimated from scrap declarations alone. It is calculated using real dimensional results collected directly from IMTE — Inspection Measuring and Test Equipment.
Each measured value is linked to its nominal and tolerance defined in QIF (ISO 23952), ensuring that quality losses reflect objective dimensional nonconformities rather than subjective reporting.
OEE quality becomes technically measurable and auditable.
Integration with MES and production orders
IVR OEE operates in conjunction with IVR MES, associating availability and performance data with specific production orders, machines and operators.
Dimensional results structured in QIF are linked to each order, enabling analysis of how process capability and statistical stability directly impact equipment effectiveness.
- Order-based effectiveness calculation
- Loss classification tied to measured characteristics
- Operator and shift comparison with dimensional impact
SPC-driven loss identification
Real-time SPC integration allows IVR OEE to identify losses caused by statistical instability, trends or out-of-control conditions. These deviations are associated with specific dimensional characteristics.
This approach enables correlation between process capability indices (Cp, Cpk) and performance losses, providing a data-supported view of process behavior.
Effectiveness analysis is grounded in statistical evidence.
Full digital thread from design to effectiveness
Engineering definitions from CAD are structured via QIF and executed through DMIS programs. The resulting inspection data feeds both MES and OEE modules without retyping or reinterpretation.
This establishes a continuous digital thread: CAD → QIF → DMIS → IMTE → MES → OEE, preserving consistency between design intent, measured reality and equipment performance.
- CAD-defined characteristics
- QIF-structured dimensional data
- DMIS program traceability
Audit-ready performance records
Availability, performance and quality data are stored as structured, traceable records. Dimensional evidence supports performance analysis and continuous improvement initiatives.
By linking equipment effectiveness to real measurement results, IVR OEE provides a defensible and technically grounded evaluation of manufacturing performance.
OEE becomes a measurable extension of dimensional quality control.
