Abstract

The behaviours of chip formation during machining heat treated SCM 3 steel with various microstructers were investgated. The obtained results are summarized as follows:<BR>1) Concerning the sufficient condition to the formation of built up edge, this reseach elucidated a new mechanism different from the previous studies, namely the temperature at front surface of built up edge was higher than that outside of tool surface. This seems to be related to strain rate distribution, degree of blue shortness and generated heat at cutting zone.<BR>2) Cutting force (R) in turning decreased with the hardness in these samples. This can be explained from a relation between R and shear angle (φ) being dependent on the thickness of deformation flow laver (Fμ) of chip. The formation mechanism of Fμ should also be considered.<BR>3) In the range of this study, a new equation to caluclate the shear angle (φ) of chip was obtained by replacing the hardness of steel and the cutting speed with the observed Fμ.
