Welcome to The CTMA Connector, a monthly newsletter designed to provide news and ideas about the Commercial Technologies for Maintenance Activities (CTMA) program. The CTMA program is a joint Department of Defense/National Center for Manufacturing Sciences (DoD/NCMS) effort promoting collaborative technology development between industry and the DoD maintenance and repair facilities. This newsletter highlights ongoing projects, serves as a forum for promoting new project ideas, and provides other news of interest to the program. Our goal is to stimulate your participation and solicit your input. Feel free to submit items for the newsletter as well as any suggestions to make it more useful. More information about the program can be found at http://ctma.ncms.org/. To subscribe or unsubscribe to the CTMA Connector, send a message to listserv@listserv.ncms.org with "subscribe CTMANewsletter" or "unsubscribe CTMANewsletter" in the subject line.


We welcome the following organization as a participant in the CTMA program:

Rolls-Royce Corporation

Rolls-Royce is a developer and manufacturer of gas turbine engines for aircraft, rotor craft, industrial and marine applications.

New project approved:  Robotic Painting Optimization of Military Vehicles

Few commercial robotic painting systems in use require the versatility that is required for the military vehicle painting scenario.  A major advance in systems approach is postulated in this project to address this requirement.  This project involves combining the abilities of state-of-the-art “vision technology” and friendlier robot programming methodologies now in use in commercial robotic painting applications.  However, until this combination can be demonstrated to show high reliability and affordable operational and support costs, the concerns of reliability and cost remain.  The principal focus of this project is to address these programming/operational concerns by using selected visioning hardware and software, coupled with robotic programming methodologies, to demonstrate the ability and inherent reliability needed to address these software and system related issues.  A second concern is that of the actual maintainability of the “vision” and robotic painting hardware. 

The Robot Painting Optimization project will bring the following benefits:

  • A capability assessment of state-of-the-art vision and robotic painting technologies against the technical requirements for applying military camouflage painting patterns to military vehicles.
  • A preliminary risk and economic assessment of robotic application of military camouflage patterns to military vehicles and forecast for Phase II-A demonstration.
  • Physical demonstration to prove-out state-of-the-art robotic and customized vision technologies’ capability to identify and apply military camouflage painting patterns to a military vehicle having various features and sizes.
  • An equipment plan and layout for a full-scale robotic painting system equipped with the necessary vision capabilities for the new painting facility at U.S. Marine Corps Maintenance Center at Barstow.
  • An assessment of the technical risk and economic business case for the installation of a full-scale robotic painting system at the U.S. Marine Corps Maintenance Center at Barstow.
  • Installation and validation of vision equipment (and demonstrated interface with the robots) for the full scale-up at Barstow and a full summary report of the entire project.  
  • Reduction of paint costs through less paint per unit volume.  
  • A substantial decrease in paint application time per unit.  
  • An increase in quality of the camouflage patterning.  
  • An improvement in worker health and welfare through less direct exposure to the VOCs of the painting operation.  

DoD participants include the Marine Corps Maintenance Center, Barstow, and the Red River Army Depot.  NCMS project manager is Connie Philips, 734-995-7051.

 


New Project Ideas Seek Participants

 

Coating Removal & Surface Prep

 

The use of laser energy to remove paints, sealants, corrosion and other coatings becomes increasingly feasible with the progressive improvements in the basic technology and the energy delivery systems. The recent diode-pumped, pulsed, solid-state lasers are providing progressively greater wall plug efficiencies and smaller size (footprint.)  They also permit energy delivery to the work surface via fiber optics. Consequently, today’s systems are more flexible, portable and cost-effective than they were only a few years ago. Items can now be cleaned without extensive disassembly, and without bringing them to the ‘laser lab.’ The laser can now travel with the other portable maintenance equipment, such as welders and compressors. 

 

Advantages of laser cleaning and decoating are not trivial. First is the environmental advantage, brought about by the fact that the laser needs no secondary waste stream. It’s a ‘zero-added-waste’ technology. Moreover, many coatings are partially volatilized, so even the coating residues are often reduced by as much as 70%. Compared to traditional stripping/cleaning methods, the reductions in disposable waste approach orders of magnitude when the laser is employed.

 

We are looking for industry participants to develop this technology and associated applications.  Current depot interest includes: Oklahoma City Air Logistics Center, Marine Corps Maintenance Centers (Barstow, Albany) , Pearl Harbor Naval Shipyard, Anniston Army Depot, and Warner Robins ALC.  NCMS contact is Steve Hale, 734-995-2195.
