تكاليف الجودة السيئة من عدم التحكم بالمقاس (Cost of Poor Quality from Gauge Control Failures)
Definition
Gauge control failures (thickness, width, flatness, surface quality) are common in manual rolling environments. Root causes: (1) Operator skill variance; (2) Wear in rolling stand bearings/calibration drift; (3) Lack of inline measurement feedback; (4) Thermal expansion (temperature fluctuations in rolling process). Consequences: (a) Customer rejection of full coils/bundles; (b) Rework through re-heating and re-rolling (energy waste + time delay); (c) Scrap write-offs if out-of-spec material is unsuitable; (d) Warranty claims when downstream fabricators (structural steel, automotive) experience failures due to improper gauge.
Key Findings
- Financial Impact: Defect/rework rate: 2–5% of production volume = AED 8–20M per facility per year. NDT/inspection labor: 100–150 additional labor hours/month = AED 0.5–1.5M annually. Customer compensation/refunds: 0.5–1.5% of sales = AED 3–10M. Scrap material write-off: 1–2% of material cost = AED 2–5M.
- Frequency: Daily (intermittent batches) to weekly (cascading failure patterns); elevated during high-speed runs or material transitions
- Root Cause: Lack of: (1) In-line eddy current / optical thickness gauges on rolling lines; (2) Closed-loop feedback to hydraulic gap-setting systems; (3) SPC charting discipline; (4) Preventive maintenance schedules for stand bearings and calibration.
