Abrasive Cutting

Abrasive-cutting processes are widely used to obtain semi-finished products from metal bars, slabs, or tubes. Thus, the abrasive cutting-off process is applied when requiring precision cutting and productivity at a moderate price. Cut-off tools are discs composed of small abrasive particles embedded in a bonding material, called the binder. This work aims to compare the cutting performance of discs with different composition, in dry cutting of steel bars. To do that, disc wear was measured and disc final topography was digitalized in order to determine both disc surface wear patterns and if the abrasive particles bonding into the binder matrix was affected. In addition, X-Ray inspection gave information about the abrasive grit-binder bonding. Therefore, the method here presented allows identifying discs with a superior abrasive-cutting capability, by combining profilometry and tomography to define micrometrical aspects, grit size, and binder matrix structure. Results led to the conclusion that discs with high grit size and protrusion, high grit retention by bond material, and closer mesh of fiberglass matrix binder were the optimal solution.

Key Aspects

The two cutting tools obtained from ultra-fine grade Ti (C,N)-based cermets were tested in the dry cutting of a medium carbon steel (AISI1045). Microstructure and mechanical properties were studied. Wear mechanisms (mainly diffusion and oxidation) were investigated in detail and compared each other in order to better understand key aspects due to thermal wear mechanisms. Comparing tool A with B, under the adopted cutting conditions, the tool A has a better resistance to oxidation deformation in machining medium carbon steel due to the higher hardness, although tool B has higher bending strength and fracture toughness.

The phenomena associated with the permanent deformations of the metals have attracted the attention of investigators during the last 100 to 150 years, and have inspired mathematically-minded observers in their endeavour to formulate mechanical rules or laws by which ductile metals flow under prescribed conditions. While the theory of elasticity is mostly concerned with very small strains, a theoretical treatment of the permanent or plastic deformations of metals must also frequently take account of strains of an order of ten to a hundred—and even more—times larger than the strains that can be sustained by them elastically. The engineering means for dealing with finite strains of this order will be reviewed in the lecture, and certain new types of strains that seem to offer possibilities for expressing the stress-strain relations required for developing the theories of the flow of metals under various conditions will be introduced. Several ideal substances, representing behaviour of metals or of other materials under different conditions, may be considered. For a perfectly plastic substance a special solution is quoted for a plane problem and for plastic shells with rotational symmetry. A case of the creep of metals at eleyated temperatures will be mentioned. Experiments made during the war years on the propagation of the plastic zone along mild-steel bars tested under tension, on the flow of copper and of medium carbon steel under combined stresses in the strain hardening range (including observations regarding the ensuing types of fractures which were observed), and experiments on the effect of the speed of deformation in these metals under normal and at elevated temperatures over a wide range of the rates of strain, will be reported.

Quenching And Tempering

One of ways to improve properties of materials without changing the product shape toobtain the desired engineering applications is heating and cooling under effect of controlledsequence of heat treatment. The main aim of this study was to investigate the effect ofheating and cooling on the surface roughness, microstructure and some selected propertiessuch as the hardness and impact strength of Medium Carbon Steel which treated at differenttypes of heat treatment processes. Heat treatment achieved in this work was respectively,heating, quenching and tempering. The specimens were heated to 850°C and left for 45minutes inside the furnace as a holding time at that temperature, then quenching process wasperformed in four types of quenching media (still air, cold water (2°C), oil and polymersolution), respectively. Thereafter, the samples were tempered at 200°C, 400°C, and 600°Cwith one hour as a soaking time for each temperature, then were all cooled by still air. Whenthe heat treatment process was completed, the surface roughness, hardness, impact strengthand microstructure tests were performed. The results showed a change and clearimprovement of surface roughness, mechanical properties and microstructure afterquenching was achieved, as well as the change that took place due to the increasingtoughness and ductility by reducing of brittleness of samples.
