The effect of cutting speed and width of cut on the machining characteristics of a graphite/epoxy composite material were investigated. The interlaminar tensile strengths of the machined specimens were measured. Damage in the form of cracks, delamination, and fiber rotation were detected in the machined region. The depth of the affected zone and the severity of the damage decreases with an increase in cutting speed. The interlaminar tensile strength of the machined specimens increases with an increase in cutting speed. The results are interpreted in terms of the tool force generated during the machining operation.
