Superior Performance Adaptive Tightening Control Adaptive Tightening Control (ATC)* automatically adjusts for different joint designs and part variations during each tightening cycle by dynamically managing speed and power to the motor. * Patented • Quality Improve Capability • Productivity Reduce Cycle Time • Simplicity Reduce Setup Time • Ergonomics Optimize Reaction • Durability Increase MTBF MTBF = Mean Time Between Failures www.StanleyAssembly.com
Adaptive Tightening Control ATC Application Example Seat Belt Install • Retractor bracket to B pillar (2 fasteners) • Seat belt anchor to cab floor (1 fastener) • Same fastener drive type and torque target • But drastically different joint compositions B Pillar www.StanleyAssembly.com
Adaptive Tightening Control ATC Application Example Battery Tray Secure • Two very long fasteners (soft joints), one hard joint • Same fastener drive type and torque target • Hard joint requires drastic downshift to control • Causes excessive cycle time for long fasteners Battery www.StanleyAssembly.com
Adaptive Tightening Control ATC Handles It Automatically ATC Executes During Every Rundown • NO “learn mode” • NO “fine tuning” • NO Laptop Required Alternatives to ATC (for applications with varying joint rates) • Compromise Capability, Cycle Time, and Ergonomics • Manually Configure Multiple Parameter Sets (requires operator to make parameter selections during job) www.StanleyAssembly.com
Adaptive Tightening Control Manual Downshift Torque Target Torque Downshift Torque Time Low Speed % Speed Reduction is a Function of Fixed Thresholds Speed Free Speed % www.StanleyAssembly.com
Adaptive Tightening Control ATC versus Manual Downshift Target Torque Torque Downshift Torque Reduced Cycle Time Time Low Speed % ATC Improves Cycle Time Speed is Higher For Most of Cycle – Completes Job Faster Speed Free Speed % www.StanleyAssembly.com
Adaptive Tightening Control ATC Automatic Mode End Torque 75% of target Target Torque P212 Torque Start Torque 25% of target P211 Time P213 End Speed 10% of rated Speed Reduction is a Function of Torque Rate Speed Free Speed 100% of rated P214 www.StanleyAssembly.com
Adaptive Tightening Control ATC Custom Mode End Torque 50 – 100% (>P211) Target Torque P212 Torque Start Torque 10 – 75% (<P212) P211 Time P213 End Speed 10 – 30% (<P214) Speed Reduction is a Function of Torque Rate Speed Free Speed 40 – 100% (>P213) P214 www.StanleyAssembly.com

Adaptive Tightening Control ATC Automatic Mode No speed or power parameters to adjust • Manages mean shift for ISO5393 Range • Hard defined as 30º from snug to target • Soft defined as 720º from snug to target ATC Custom Mode Four parameters for extreme applications • High initial or heavy prevailing torque applications • Extremely hard joints, stick-slip or chattering joints • Used to shape the ATC behavior www.StanleyAssembly.com
Adaptive Tightening Control ATC Improves • Quality by Increasing Process Capability Adapting to joint rate reduces mean shift and scatter • Productivity by Reducing Cycle Time Tool automatically runs faster on softer joints • Simplicity by Reducing Set Up Time Eliminate “fine tuning” speed on majority of applications • Ergonomics by Optimizing Reaction Force Gradual speed changes provide smoother performance • Durability by Reducing Part Consumption Gradual speed changes reduce wear on gearing www.StanleyAssembly.com
