Manual Pressure Adjustments
Equipment pressure drifted 2-3 PSI from morning setup to afternoon due to thermal effects. When pressure fell outside optimal range, gripper force dropped, causing parts to slip—brief jams and resets. Operators manually re-adjusted pressure 3-4 times per shift.
What Became Visible
Pressure monitoring combined with micro-stop logging showed perfect correlation: every time pressure drifted >2 PSI from baseline, micro-stops increased 3-5x within 30 minutes. Manual operator adjustments were reactive; the solution was automatic adjustment based on real-time pressure drift.
Automatic Pressure Compensation
Pressure control system modified to maintain set-point automatically, compensating for thermal drift. Operator no longer needed to adjust pressure; system maintained optimal operating condition continuously.
How it worked: Closed-loop pressure control automatically adjusted supply pressure to maintain constant operating pressure regardless of temperature changes.
Results
from pressure cause elimination
recovered
Micro-stops caused by parameter drift can be eliminated with automatic compensation. Manual adjustment is reactive; automation is preventive.
Operational Reality
Operators knew pressure was drifting and adjusted it manually. Systematic solution automated the adjustment, preventing the problem entirely.
