Abstract: The ploughing forces (PFs) are one of the important parameters for calculating tool life. They directly affect the stress on the tool flank face and are responsible for the wear and tear conditions of the cutting tool as well. In this study we attempted to find the impact of cutting speed on PFs, that is, the relation between cutting speed and PFs. In this paper, PFs were estimated by a new comparison method in which forces at different points of contact are added (sum of the forces) to accurately measure the PFs. The PFs estimated with this method will be more accurate than previously used methods. This paper presents the measurement results of the PFs when turning stainless steel, structural steel and aluminium alloy materials. The results of experimental studies showed that an increase in cutting speed ranging from 50 to 200 m/min resulted in an increase in PFs by 1.4-3.2 times when turning with different flank wears.
