The report outlines the procedures used and presents the data obtained during the wheel saw-cutting portion of the Cracked Wheel Investigation. The purpose of the wheel saw cutting experiment was to determine the magnitude and direction of the residual stresses in a new, as well as a service-worn, 'L' grade, 32 inch diameter, railroad wheel. These wheels were instrumented and then radially cut at two locations (180 degrees apart) to relieve the residual stresses. Data were taken using strain gages, a clip-on displacement gage, and moire interferometry. Data from all three measurement techniques and a description of the experimental procedure and equipment are included.
