Case study results for CNA Flextool use at the Boeing Renton Factory, Renton WA.

Applications Routing and drilling
   
System Configuration Five-axis, high pressure abrasive water-jet gantries
Three CNA flexible tooling systems
– Two 8′ x 50′ tables
– One 6′ x 10′ table
– Total 312 servo actuators
   
Parts Horizontal and vertical stabilizer skins
   
Aircraft 777
   
Results – Decreased tool lead time by 10 months
– Lowered non-recurring tooling costs by over $8.0M
– Lowered recurring costs by over $10.0M since installation
– Achieved final part accuracy of ±0.010-0.015″ (from ±0.050″)
– Saved facility space 30,000 SF
– Increased machine utilization time 200%
– Project duration from concept to production was 16 months (compared to 30 months with traditional tooling system)
– Reusable on future programs
– No part rejections due to tooling
