The incremental ring compression test (IRCT) was developed to investigate the friction condition in cold-rolling process of spline or thread shaft. During IRCT process, the upper die is loaded intermittently and new oil film between ring and dies will appear, which can reflect the lubrication characteristic in the spline or thread rolling process. The Coulomb friction coefficient and Tresca friction factor were determined by the IRCT, respectively. The magnitude of friction obtained by IRCT presents a notable difference from that obtained by traditional ring compression test. The results provide an accurate friction parameter for studying the cold-rolling process of shaft part.
