Abstract :The effects of different blade coating materials on force demands were examined in the present study. The force demands when cutting grape branches with St-52 steel, polytetrafluoroethylene insert ignore into journalissuearticles values(PTFE);-coated and Soft Teflon insert ignore into journalissuearticles values(STP);-coated lopper blades were measured. A universal testing machine was used as the simulated cutting task together with a force cell in the laboratory. Grape branches were the testing material. The differences between the force demands of blades were significant insert ignore into journalissuearticles values(P<0.01);. The PTFE-coated blade resulted in a 30.69% and 25.63% lower average force compared to the STP-coated blade and ST52 steel-surfaced blades for the 6-9 mm diameter sample group respectively. When the other diameter group is examined for the same materials, the PTFE-coated blade resulted in a 17.76% and 13.82% lower average force respectively. Also, a PTFE-coated blade was obtained for both diameter groups at the smallest energy value. The differences between the energy demands of lopper blades were significant insert ignore into journalissuearticles values(P<0.05);.
