Tool Crib Management
Why Sigma
- Tool crib designed around takt and availability, not admin workload
- Standardisation across parts reduces SKUs and purchasing noise
- Min–max logic based on real consumption, not guesswork
- Tool-life and regrind loop built into daily discipline
- Prevents stock-outs and wrong-tool-at-machine errors
- Visibility into abnormal consumption and cost creep
- Kitting + presetting to cut changeover time
- Simple dashboards that production and maintenance can run
Where Sigma Fits In
Line Stops Because Tools Aren’t Available?
Tool Inventory is High but Still Unreliable?
Make Tool Availability a System, Not a Chase
Tool Master & Standardisation
Scope: Common tools across machines/parts, reduce duplicates, simplify SKUs.
Deliverables: tool master list, standardisation map, approved equivalents.
Min–Max & Reorder Logic
Scope: Consumption-driven stocking, lead-time alignment, criticality tiers.
Deliverables: min–max plan, reorder triggers, critical spares list.
Kitting & Presetting System
Scope: Machine-wise/part-family tool kits, setting discipline, faster changeovers.
Deliverables: kitting plan, setting sheets, crib layout inputs.
Tool Life Tracking & Abnormal Consumption Control
Scope: Track tool life, breakage patterns, regrind cycles, variance causes.
Deliverables: tracking format, abnormal consumption rules, weekly dashboard.
Regrind/Sharpen Loop Management
Scope: Regrind frequency, quality checks, scrap criteria, turnaround control.
Deliverables: regrind SOP, acceptance checks, vendor/turnaround plan.
Governance & Reporting Cadence
Scope: Simple reviews that keep it working without heavy admin.
Deliverables: KPI snapshot template, review cadence, responsibility matrix.
