SUMMARY
Use Validated Speed to define the maximum production speed a line can reliably achieve under normal operating conditions. Validated Speed forms the baseline for OEE calculations, Speed Loss, and production performance monitoring.
WHAT THIS IS
Validated Speed is the verified maximum production speed that a machine or production line can achieve under normal operating conditions. It is sometimes referred to as the nominal speed and is typically measured in pieces per minute.
Unlike Expected Speed, which represents a realistic production target, Validated Speed represents the technical capability of the equipment and is used as the reference point for performance calculations.
For slower production processes, Validated Speed can also be derived from the product's cycle time.
WHY IT MATTERS
Validated Speed is the foundation for several production calculations within Factbird.
Using an accurate Validated Speed helps:
- Measure Speed Loss accurately.
- Calculate Expected Speed.
- Monitor production performance against the machine's capability.
- Improve the accuracy of OEE Performance calculations.
- Configure performance-based alarms and dashboards.
WHEN YOU WOULD USE THIS
Use this when:
- Configuring a new production line or sensor.
- Setting up OEE calculations.
- Configuring Speed Alarms.
- Reviewing production performance.
- Investigating Speed Loss.
HOW IT WORKS
Validated Speed acts as the benchmark against which actual production speed is compared.
For example:
- Validated Speed = 150 pieces/minute
- OEE Target = 60%
- Expected Speed = 90 pieces/minute
During production, Factbird compares the actual production speed with the configured Validated Speed. Any reduction in production speed while the line is running contributes to Speed Loss.
For production processes that use cycle time instead of pieces per minute, Validated Speed can be calculated using:
- Validated Speed = 60 ÷ Cycle Time
For example:
- Cycle Time = 2 seconds per piece
- Validated Speed = 30 pieces/minute
KEY TERMS / COMPONENTS
Validated Speed
- The verified maximum production speed a machine or production line can achieve under normal operating conditions.
Expected Speed
- The planned operating speed used to calculate shift and batch targets.
Speed Loss
- The production time lost when the line runs below its Validated Speed while still producing.
Cycle Time
- The time required to produce a single item. It can be converted into a Validated Speed for slower production processes.
OEE Performance
- The OEE component that compares actual production performance against the Validated Speed.
COMMON MISUNDERSTANDINGS
- Validated Speed is not the same as Expected Speed. Validated Speed represents the machine's verified capability, while Expected Speed represents the planned operating target.
- Setting a higher Validated Speed than the machine can realistically achieve will increase reported Speed Loss and reduce OEE Performance accuracy.
- Changing the Validated Speed only affects future production data. It does not retroactively update historical production records.
