Summary of Expertise: Listed with other top experts in: 
MECHANICAL SEALS RESEARCH. Expert is Co-Director of the Western Michigan University Tribology Laboratory, which has several active investigations of friction and wear processes. He is in the second phase of a multi-client study of blistering in carbon-graphite mechanical seal faces. Other research programs evaluate ceramic materials such as silicon carbide, tungsten carbide, and nanocrystalline diamond coatings as candidate materials for mechanical seal applications in pumps and mixers and pin-on-disc wear tests for wear resistant polymers against metal surfaces. He routinely uses interference microscopy to characterize surface topography, a particle counter to measure contamination of fluids and a mercury porosimeter to characterize pore size distributions.

DESIGN FOR MANUFACTURABILITY; MACHINE TOOL DESIGN. Expert has an extensive background in manufacturing research and development as well as machine tool design and development. He is knowledgeable of precision forging machinery and proprietary machine tools for forging high toughness automotive differential gears from metal powders. This background is complemented by experience at the university level where he teaches metallurgy, manufacturing processes, and mechanical engineering design and conducts industry-sponsored research. He is the Past Chairman of the Design for Manufacturability Committee of the American Society for Mechanical Engineers (ASME). In this role at ASME, he organized the 1993 Design for Manufacturability Conference and is currently organizing a satellite video conference on the subject.

MANUFACTURING TECHNOLOGY. Expert has broad experience in manufacturing processes and technology. He teaches short courses on manufacturing processes, forging die design, tribology, and materials technology for various clients as well as for the Forging Industry Association. While in industry, he developed processes for forging powder metal gears, for manufacturing sol-gel and alumina-zirconia abrasive grains, and for producing silicon carbide. At the University, he has conducted research in several areas of the lost foam casting process and completed a major study of the potential use of various granular ceramic media as recyclable replacements for foundry sand.

GRINDING ABRASIVE MATERIAL; ABRASIVE BLASTING; FUSED ALUMINUM OXIDE. Expert's experience in abrasives covers grinding wheels, blasting grain, and abrasive grain technology and product development. He was directly involved in the development of sol-gel ceramic abrasive grains. He directed off-shore technology transfer projects for manufacturing fused aluminum oxide and alumina-zirconia abrasive grains. He was the Technical Director for a leading producer of fused aluminum oxide and consults with a foreign producer of the material. Expert can answer in-depth questions regarding metal grinding and abrasive blasting, in particular glass shot, sand, and grit blasting.

Consulting Services:
Selected Consulting Examples:
  • Client sent samples of grinding wheels to determine the constituent abrasive grain, binder, and active grinding aids. Expert used light microscopy to partially identify the abrasive grain type. He also sent samples of the wheels to three different laboratories for state-of-art analyses to confirm the grain type, binder composition and to determine the active grinding aids. This project could not have been completed by a person unfamiliar with the typical composition of grinding wheels.
  • Client showed Expert a broken frame that was designed to withstand loads exerted by three in-line ultra high pressure cylinders. The frame was made from cast iron with steel extensions bolted onto the end. Expert and a faculty colleague determined by testing and by fracture surface examination that the cap screws that were used to bolt the steel extensions onto the frame had been over-torqued during assembly. One or more of the cap screws failed in tension when the cylinders were pressurized. This resulted in eccentric loading of the frame creating bending stresses that resulted in fracture.
  • Client presented a compressor rotor with several blades severely bent and evidence that the rotor had contacted the housing. Expert cut the rotor into 16 slices with a band saw and determined that the initial failure was initiated in the interior of one blade at a heat affected zone where the blade had been twisted into a tighter arc and then welded into that configuration during the original manufacturing of the compressor. The locally higher stress resulted in a high cycle fatigue crack after 25 years service. Thie crack caused the blade to deflect into contact with the compressor housing. A piece of the blade broke loose and jammed between the compressor disk and the compressor housing, bending the main rotor. The resulting eccentricity and unbalance in turn caused the rotor to contact the journal bearings, labyrinth seals and caused the impeller to rub against the compressor housing. The bearings and seals were partially melted into adherence onto the rotor and the compressor impeller was machined in an eccentric pattern reflecting the rotor's deflected shape. (Project completed with a colleague).
  • Client presented a broken leaf spring from the trailer of a semi truck. The spring segment had crashed through the windshield of a car that had been following the truck, severely injuring the driver. Examination of the fracture surface showed several beach marks, each one evidence of a fatigue fracture. The presence of several beach marks on one fracture surface indicates overloading of the trailer in the recent past.
  • Client asked if the manufacturing process used at an environmentally contaminated site could be identified. The buildings had been removed to their foundations. Expert found metal pieces on the grounds that were clearly flash trimmed from forgings. He then determined that the shape of the remaining concrete foundations corresponded to piers for forging presses. These two pieces of evidence showed that the environmental contaminants could not be traced to the prior occupant.
