1. Review practices and decision process at ANC and other national and private cemeteries. Gather current guidelines for maintenance decisions for:
- Review replacement procedures at ANC
- Surface Analysis and survey practices
- Cleaning procedures, costs and benefits
- Polishing procedures, costs and benefits
- Making the re-cut, repair, replace decision
- Research practices at other locations
|
1. Draft Purchase Recommendation
Prepare a preliminary list of router manufacturers, software sources, scanner sources for purchasing Beta Test Phase equipment. Prepare draft specifications to test
- CNC routers and software
- Scanners for surface roughness, letter shapes
- Rubber sheeting & warping software
- Control software to generate cutting instructions
- Measures of hardness and stone properties
- Random samples to relate properties to durability
- GPS and mapping software
- Photographic and Gravestone record keeping software
|
| 2. Draft Guidelines for Cemetery Practices
Gather data and resources for:
- Economics and timing of headstone replacement
- Weathering data for headstones/ gravestones
- GPS and mapping of cemeteries and graves
- Use of photographic databases for cemetery records
- Cemetery record keeping practices
- Biodeterioration, biodegradation, biocide practices
|
2. Draft Stone Cutter Procedures and Best Practices
Work with marble quarries, stone industry, sculpture industry to document best practices in stone cutting, and measures related to headstone wear and durability.
- Data and demonstrations
- Cutters speeds and forces, feed rates
- Hardness and durability, resistance-to-wear data
- Surface roughness and resistance to wear
- Letter shapes and resistance to wear
|
| 3. Share Information
Share the information gathered with others through the ANC and other websites - throughout the process. Ask for feedback and cooperation from various groups. Since the surveys rely heavily on photographic and scanning technologies, that information can be shared with families. Regular documentation of stone properties and wear will be of use to a wide community.
- Cemetery Managers/ Directors
- Cemetery Preservation Groups
- Stone Conservation Groups
- Conservators, Architects, Designers, Sculptors
- Historic Preservation groups at state and local level
- Cemetery records-keepers
- Cemeteries in other countries
- Veterans Groups
- Genealogy Groups
- Private researchers
- Families of Veterans

3. Purchase Beta System
- Scanners
- Calibrated cameras with 3D recovery
- Laser scanners for CNC router scans
- Flat scanners for Letter scans
- Post recovery from existing photos
- CNC cutter
- Power requirements, power monitoring
- Horizontal and/or vertical operation
- Speed and piece-rate cost trade-offs
- Water cooling, vacuuming
- Survey Computers and Hand-helds
- Laptops, Hand-held, other
- Windows, 40G, USB 2.0 external drive, 17 in monitor, 2.2 GHz+, 256 M, Software
- Related Equipment and Supplies
- Generator or Motorized Cart
- Water supply, hoses, cleaning supplies
- Polishing supplies and equipment
- Cutting heads, replacement parts
- Repair supplies
|
4. Draft Recommendations
- Cemetery Survey Procedures
- Use of GPS
- Mapping of cemeteries and graves
- Online sharing of grave photos at ANC
- Share development of biocide best-practices
- Share development of cleaning best-practices
- Share development of record keeping best practices
- Linking graves to genealogy, biography and historical resources on the web.
- Solicit cooperation in linking information on veterans to their gravesites.
|
4. Beta Test of Scanners and Cutters
Test the system in increasingly real applications. Draft operators manual
- Test on practice pieces - flat
- Test on practice pieces - vertical
- Re-cut "good" letters and polish
- Re-cut "bad" letters and polish
- Re-cut "new" letters and polish
- Resurface whole face on practice piece
- Chemical analysis of cuttings
- Surface scans to compare before and after and test predicted volume removed against actual
|
5. Final Report
- Take a few of the items from the Draft above and expand them into final recommendations - as starting point for community development of best practices.
- Write a summary of what has been accomplished and what yet remains to be done.
- Websites can contain much of the gathered data - of immediate and enduring use to groups listed in 3 above.
|
5. Final Report
- Operators Manual for Cleaning, Polishing, Cutting
- Hardness, surface roughness, material properties testing
- Cost accounting and estimation model
- Specifications for cutters for various types of stone cutting and processing - for cemeteries
