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
Superior Performance
Quality Improve CapabilityProductivity Reduce Cycle TimeSimplicity Reduce Setup TimeErgonomics Optimize ReactionDurability Increase MTBF
MTBF = Mean Time Between Failures

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 targetBut drastically different joint compositions

Adaptive Tightening Control
ATC Application Example
Battery Tray Secure
Two very long fasteners (soft joints), one hard jointSame fastener drive type and torque targetHard joint requires drastic downshift to controlCauses excessive cycle time for long fasteners

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 ErgonomicsManually Configure Multiple Parameter Sets(requires operator to make parameter selections during job)

Adaptive Tightening Control
ATC Automatic Mode
No speed or power parameters to adjust
Manages mean shift for ISO5393 RangeHard defined as 30º from snug to targetSoft defined as 720º from snug to target
ATC Custom Mode
Four parameters for extreme applications
High initial or heavy prevailing torque applicationsExtremely hard joints, stick-slip or chattering jointsUsed to shape the ATC behavior

Adaptive Tightening Control
ATC Improves
Quality by Increasing Process CapabilityAdapting to joint rate reduces mean shift and scatter
Productivity by Reducing Cycle TimeTool automatically runs faster on softer joints
Simplicity by Reducing Set Up TimeEliminate “fine tuning” speed on majority of
applications
Ergonomics by Optimizing Reaction ForceGradual speed changes provide smoother
performance
Durability by Reducing Part ConsumptionGradual speed changes reduce wear on gearing
