How to perform automatic adjustments during calibration?
Automatic adjustment during calibration is essential for maintaining tool accuracy and ensuring consistent tightening performance on modern assembly lines. The process typically includes the following steps:
1. Monitor Tool Capability
Use SPC (Statistical Process Control) to verify that tools meet required performance standards. SPC helps detect deviations early, ensuring process stability and preventing quality issues.
2. Respond to Alerts
When an alert shows a tool is out of tolerance, recalibration is required. Advanced systems can trigger this automatically, minimizing downtime and reducing the risk of human error.
3. Perform Automatic Adjustment
With advanced solutions, such as systems equipped with a wireless rotary transducer (WRT), the automatic adjustment process can be completed entirely without cables using infrastructure mode. These systems can run multiple tightening cycles (up to 30) to recalibrate the tool with high precision.
4. Access Results and Traceability
All calibration results are stored directly in the transducer and can be integrated into production monitoring platforms for full process traceability. The integrated WRT database securely stores up to 5,000 curves and 50,000 results, ensuring easy access for audits, compliance, and quality reporting.
What is residual torque checking?
Residual torque checking is the process of measuring the remaining torque on a fastened joint after the tightening operation is complete. This verification step ensures the joint still holds the correct torque level and helps identify any potential relaxation that could impact fastening quality.
Why is residual torque checking important?
It is a critical step for safety-sensitive applications. Detecting joint relaxation early prevents failures and guarantees compliance with torque specifications.
When should residual torque checking be performed?
Residual torque checking should be performed:
During a new assembly process to confirm proper tightening.
After the initial tightening to verify the relaxation under torque or over torque conditions.
During production quality checks to ensure tightening consistency.
When evaluating joint behavior, especially if relaxation or torque variation is suspected.
As part of capability tests or periodic validation procedures on assembly lines.
How is residual torque checking performed?
Residual torque can be measured after tightening with various tools, including:
Pulse tools
Continuous tools
Wrenches
Residual torque measurement can be performed using the Q-Shield S, Q-Shield C, or Q-Audit
What happens if the residual torque is outside the tolerance?
If the residual torque does not meet the specified tolerance, several corrective actions are possible:
Tool calibration check
Joint inspection
Retightening and rechecking
How to detect abnormal curves in real-time?
Desoutter’s Curve Analytics solution continuously monitors tightening curves on assembly lines. Each tightening curve is analyzed live and grouped into clusters based on its behavior. If a new tightening curve falls outside the acceptable range, the system triggers an instant alert for immediate corrective action.
What happens when a tightening anomaly is detected?
When an abnormal tightening curve is identified, supervisors receive a live alert. This enables quick intervention - either reworking the tightening path or recalibrating the tool if necessary. The solution uses AI to classify anomalies and adapt instantly to production changes, reducing downtime, and improving tightening process reliability. Desoutter proposes the Demeter solution for curve analytics detection and analyze.
