6. Machine Configuration • Goal: Determine the optimal configuration of machines to reduce production time and cost. • Options • Keep the old machines, Liner cell needs to be moved anyway, savings will come by consolidating these machines and figuring out a good layout • Buy a new CNC VTL, we are looking at some machines that are capable of doing most of the steps in the process, reducing set up time. R· I· T Mechanical Engineering Department

7. Machine Configuration • Preferred Machine Specifications • Capable of running any liner from 14 in up to 42 in • Chuck size around 50 in • Maximum tooling height around 60 in • Live Tooling • Reducing changeover time in operations • Horizontal milling attachment • Can be used for porting • Must have x and y axis capabilities • Inspection probe • Inspect liner inside the machine so that the operator does not have to pull it out to do the inspection process. R· I· T Mechanical Engineering Department

8. Machine Configuration • Benefits of a new CNC VTL • Eliminate the grinding operation • Possibly eliminate the bore sheet and machine part to the print instead • Reduce operator errors • Ultimately the deciding criteria will come down to which option has the best return on investment over time compared to the current process. • With a new machine we think that we can cut production time, cost and man power. • The new configuration will also be versatile enough to handle higher work loads. R· I· T Mechanical Engineering Department

9. Cell Layout • Moving Shop 21’s Liner Cell to Shop 6 and 17 • Planned Improvements: • Greatly reduced travel time and distance (Present Base Route seen here) • A more centered layout • Improve Product flow R· I· T Mechanical Engineering Department

10. Cell Layout • The Probable Options • “As Is” process: • Use of the same machines presently being used • No new machines added • “Improved” process: • Replacement of the grinder with a vertical turning lathe (VTL) • The grinder will become unnecessary • “Re-Developed” process • Purchasing and using a multi-axis CNC machine as part of the main process flow. • Present tools will be kept to back up the CNC R· I· T Mechanical Engineering Department

11. Cell Layout • Possible looks at Re-layouts • Many factors to still consider: • Which unused machines can we scrap and replace? • Use or need of high and low bay space R· I· T Mechanical Engineering Department

12. Process Improvement Goal: • Provide visibility to management and operators on metrics: • Safety • Productivity • Quality • 6S for a clean and sustainable workplace • Standard work for consistent process, easy training and identification of out of standard process. • Provide environment for continuous improvement R· I· T Mechanical Engineering Department

13. Process Improvement Why? • Operators • Simplified process • Able to detect and prevent defects • Understand status of part/line at all times • Safer workplace • Managers • Have knowledge of part/line status at all times • Immediately detect out of standard conditions • Easy to train new operators, cross train current R· I· T Mechanical Engineering Department

14. Process Improvement How? • Metrics • Productivity (On time delivery, output/day, part status, cycle time, down time, weekly schedule) • Safety (Safe work days, accidents) • Quality (Defects, number good parts) • 6S • Labeled tool storage, machine locations, floor markers, cleaning schedule, audits • Standard Work • Work charts, combination tables • Continuous improvement • Problem solving board w/ lean training • Morning market R· I· T Mechanical Engineering Department

15. Material Handling • Current Material Handling Procedure: • Liners set vertically onto wooden pallets, moved by forklift • Causes parts to fall if forklift must stop short, resulting in defects • Current Defect Cost: $40,632 (Jan-Sep 2009) • Concerns: • Safety • Ease of Travel • Minimize Product Defects • Secure liners during travel • Support Adequate Load • Largest drum dimensions: • 42” OD x 55” tall • 2000 lb weight R· I· T Mechanical Engineering Department

16. Material Handling • Pallet Fixture/Modification • Create fixture for pallets:Flat piece with indentation to allow liner to settle, secure with ratchet straps • Modify wooden pallets:Remove center pieces of pallet to allow liner to settle, secure with ratchet straps http://en.wikipedia.org/wiki/Drum_%28container%29 R· I· T Mechanical Engineering Department

17. Material Handling • Moving Shop 21’s Liner Cell to Shop 6 and/or 17 • Dimensions • 48" x 48" x 36" • Features: • 10,000 lb rated ratchet strap attaches at 3 different heights • Can be moved using forklift • Doubles as storage unit Cost: $812 *Designed originally for gas cylinders http://www.usasafety.com/gas-cylinder-transport-pallet-forklift-21-cylinders-p-49.html R· I· T Mechanical Engineering Department

18. Material Storage • Functions of Drum Rack • Support load of drums • Each shelf can support 4,825 lb • Total capacity is 14,475 lb • Restrict drum movement • Individual Brackets • Safety • Built to OSHA standards • Cost - $608.25 ea. • http://www.materialflow.com/index.cfm?mf=browse.showPart&partClassID=670&PName=Drum%20Pallet%20Racks R· I· T Mechanical Engineering Department

19. Material Storage • Dual Purpose • Drum rack could be used for liners • Standard drum dimensions • 22.5” OD x 34.5” tall • Modifications needed: • Deeper shelf for liners • Support for large OD liners • Interchangeable brackets http://en.wikipedia.org/wiki/Drum_%28container%29 R· I· T Mechanical Engineering Department

20. Material Storage • Cart designed for liners • Largest drum dimensions • 42” OD x 55” tall • 2000 lb weight • Features: • Mobility for liners • Support for large OD liners • Doubles as storage unit • Liners stored vertically • Take up less space (4’ x 4’) • Will not interrupt walkway R· I· T Mechanical Engineering Department
