“…A similar friction model is used in [Kim 1999] in a thermoviscoplastic Eulerian finite element model to predict the effects of increasing edge radius on cutting forces (and comparison to experiment). A model proposed in [Chang 1999] predicts the effect of a chamfered, rounded, or worn edge on the shear plane and, hence, cutting forces. The approach assumes a constant shear stress and uses geometry considerations to determine the shear plane size and orientation.…”

This paper aims to provide experimental data in support of a modified theoretical model for quantifying the effect of cutting tool edge geometry on machining forces. A previously published slip-line model is simplified and extended to the case of turning. Several sets of machining experiments were run with customfabricated cutting inserts of varying edge hone radius and chamfer geometry. Cutting forces were measured using a dynamometer during cutting.Results show that varying edge geometry can have a major effect on cutting forces.The developed model effectively captures the edge phenomenon and its effect on cutting forces and also offers a glimpse of how the edge geometry can affect dynamic process damping.

The present study utilises the compressive split Hopkinson pressure bar to investigate the dynamic flow behaviour of S15C low carbon steel at temperatures ranging from 25 to 800uC. The effects of strain rate and temperature on the mechanical response and microstructure of the metal are evaluated. The flow stress of S15C low carbon steel is found to increase with increasing strain rate and to decrease with increasing temperature. Furthermore, the material temperature sensitivity is enhanced at higher strain rates. The study determines the strain rate sensitivity parameter and the activation volume under various strain rates and temperatures. It is found that the activation energy DG* varies as a function of strain rate and temperature and attains a maximum value of 62 kJ mol -1 under the current test conditions. A Zerilli-Armstrong bcc constitutive model is applied to describe the high strain rate plastic behaviour of S15C and is shown to produce acceptable results. Microstructural examination by TEM reveals that the dislocation density and degree of dislocation tangling both increase with increasing strain rate. Additionally, TEM observations indicate that a higher strain rate reduces the size of dislocation cells. Furthermore, it is shown that the annihilation of dislocations occurs more readily at elevated temperatures. The current results provide a valuable reference for the application of S15C low carbon steel in high speed plastic forming processes.
