Claimed cycle: 3.6 s
Measured median: 4.2 s
Format: Waterfall of time. Speed-override pep talk 아님.
Cycle 4.20 s
├─ Wait for part present .......... 0.85 s
├─ Approach / travel .............. 0.70 s
├─ Process (dispense) ............. 1.10 s
├─ Retreat / clear ................ 0.55 s
├─ Handshake / MES bit ............ 0.45 s
└─ Micro-recoveries (avg) ......... 0.55 s ← “3.6”의 lie
Bar 1 — Wait for part present
Sensor chatter + operator pre-stage late.
Robot fast. Line not.
Fix: presentation fixture, jerk limit 아님.
Bar 2 — Travel
Teach path short. Production은 temporary cable tray “one week” dogleg(third month).
Fix: clearance restore; retime.
Bar 3 — Process
지난달 dispense volume cycle budget change 없이 increase.
Physics taxed time. Marketing slide 3.6 s 유지.
Process volume grew면 cycle time grew—slide lie 안 하면.
Bar 4 — Handshake
MES complete bit slow SQL tag wait.
Robot idle “almost done.”
Fix: local handshake then async MES — genealogy honesty elsewhere.
Bar 5 — Micro-recoveries
Following-error recovery·gripper retry median 0.55 s average in.
Not rare. Not “outliers.”
Engineers lunch 후 one clean cycle time할 때 hidden.
Median은 exception인 척한 retry 포함.

Payload/inertia log는 mass lie. Punch list는 commissioning RED. Muting protocol은 scanner proof. Dress-pack guide는 cable life. This waterfall where seconds went. MES latency hide하려 speed override 올리지 마라.
