Abstract

Special metal cutting and materials tests are described for ascertaining the action of CCl4 on specimen surfaces. The experiments performed seem to support the idea that micro-cracks are formed when metals are plastically deformed in shear to high values of strain. CCl4 appears to prevent rewelding of these cracks when a compressive stress is present on the shear plane. The experimental results suggest a pre-treatment of surfaces to be burnished and a new classification of types of sliding contact.

    The results thus indicate that the OME can be quite beneficial for cutting of gummy metals, impacting industry sectors as diverse as aerospace, energy and orthopaedics. The OME likely belongs to one of the many chemical effects that have been suggested to occur in material removal processes [19–23]. However, the specificity of the effect with the nanoscale films shows that there is now a metrology tool (self-assembled monolayers (SAMs)) available to systematically probe the effect.

    Therefore, the theory for friction-induced changes in chip morphology was voided. Usui et al. [65] reiterated the penetration of surfactant molecules into micro-cracks that increased the stress concentration to yield closely packed shear planes and a uniformly distributed flow (i.e. laminar chip formation). Two new criteria were identified for the manifestation of the Rehbinder effect — (1) compressive stresses on the shearing action during tensile and torsion testing; and (2) the presence of superficial micro-cracks for surfactant molecule penetration.

    They believed that the apparent reduction in cutting force and chip thickness was because of penetration of CCl4 in the micro-cracks which led to the decrease in material strength at the shear plane [16]. Usui et al. [20] applied CCl4 on the free surface of the chip in machining of copper and reported the reduction in force which was attributed to the prevention of re-welding of micro-cracks during deformation of the chip. Cassin et al. [21] corroborated this theory in their work.

    It will be appropriate to conclude our discussion of flow modes in cutting with a brief mention of recent experimental observations on the action of surface films. Many reports exist in the literature [27–30] about how exposure of the initial workpiece surface, remote from the tool and from the surface of chip separation, to certain surface active media or solvents (e.g., carbon tetrachloride, films, inks) has an effect on the metal cutting process, most notably forces. The reports dating back to more than 70 years ago are conflicting, with most claiming modest reductions in the forces and a few even noting small increases, with metals such as Cu and steels.
