6. R· I· T Mechanical Engineering Department Machine Configuration o Goal: Determine the optimal configuration of machines to reduce production time and cost. o Options o Keep the old machines, Liner cell needs to be moved anyway, savings will come by consolidating these machines and figuring out a good layout o 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.

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

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

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

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

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

12. Process Improvement R· I· T Mechanical Engineering Department 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

13. Process Improvement R· I· T Mechanical Engineering Department 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

14. Process Improvement R· I· T Mechanical Engineering Department 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

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

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

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

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

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

20.
