Materials are tested in pairs under nominally non-abrasive conditions. The principal areas of experimental attention in using this type of apparatus to measure wear are described.

ASTM Committee G02, Blau, P, Slatter, T (2022) ASTM G133-05 - Standard Test Method for Linearly Reciprocating Ball-on-Flat Sliding Wear, This test method is designed to simulate the geometry and motions that are experienced in many types of rubbing components whose normal operation results in periodic reversals in the direction of relative sliding. The wear resulting from this mode of movement may differ from that experienced by the same materials sliding continuously in only one direction (unidirectional sliding) even for comparable durations of contact. Test loads and speeds are to be determined by the severity of the proposed application or purpose of the testing. Either of two sets of testing conditions (designated Procedures A and B) may be used.

HIlton, N, Slatter, T, Dawson, S, Lobato, H (2012) Development of Deep Hole Drilling Technology for Extreme L/D Ratio Holes with R&D into Tool Tip Tracking and Steering Technology, The project aims to push the current industry limits in deep hole drilling to increase the Length/Diameter (L/D) ratios of holes from 300:1 to 500:1. During current methods of deep hole drilling the drill has a tendency to deviate from a straight path, resulting in parts being scrapped and requiring high levels of operator intervention. The research is to focus on methods of tool tip tracking and steering of the tool tip in order to reduce the drills deviation as it progresses down the length of the work piece. This will allow a green button process to be produced eliminating the requirement for user intervention, resulting in a more efficient process with higher repeatability and more accurate holes being drilled. The research is being performed on a state of the art TBT deep hole drilling machine at the Nuclear AMRC with collaboration between the University of Sheffield, the Nuclear AMRC and Rolls Royce. Experiments have been performed in order to benchmark the machines current hole deviation at a L/D ratio of 300:1 and will be performed to investigate how selected process variables affect this deviation in straightness. The variables analysed were based on both a literature review and a survey that gathered industry opinions on the factors affecting hole deviation..
