  • application of vegetable oil based metalworking fluids in machining Ferrous Metals a review
    International Journal of Machine Tools & Manufacture, 2012
    Co-Authors: Sunday Albert Lawal, Imtiaz Ahmed Choudhury, Yusoff Nukman
    Abstract:

    The increasing attention to the environmental and health impacts of industrial activities by governmental regulations and by the growing awareness level in the society is forcing industrialists to reduce the use of mineral oil-based metalworking fluids as cutting fluid. Cutting fluids have been used extensively in metal cutting operations for the last 200 years. In the beginning, cutting fluids consisted of simple oils applied with brushes to lubricate and cool the machine tool. As cutting operations became more severe, cutting fluid formulations became more complex. There are now several types of cutting fluids in the market and the most common types can be broadly categorized as cutting oils or water-miscible fluids. In this review, the applicability of vegetable oil-based metalworking fluids in machining of Ferrous Metals has been undertaken. The advantages of metalworking fluids and its performances with respect to the cutting force, surface finish of work piece, tool wear and temperature at the cutting zone have been investigated. It has been reported in various literature that metalworking fluids, which are vegetable oil-based, could be an environmentally friendly mode of machining with similar performance obtained using mineral oil-based metalworking fluids.

  • A review of application of vegetable oil-based cutting fluids in machining non-Ferrous Metals
    Indian Journal of Science and Technology, 2013
    Co-Authors: Sunday Albert Lawal
    Abstract:

    In the beginning, cutting fluids consisted of simple oils applied with brushes to cool and lubricate the machine tool. However, cutting fluid formulation became more complex as cutting operations became more severe. There are several typesof cutting fluids nowadays and the most common can be categorized into cutting oils or water-miscible fluids. In this paper, attention is focused on recent research work on the application of vegetable oil-based cutting fluids in machining non-Ferrous Metals. The efficiency of various vegetable oil-based cutting fluids based on some process parameters such as thrust force, temperature developed at the tool chip interface and flank wear during machining of some non-Ferrous Metals using different tool materials were highlighted. The results obtained established vegetable oil-based cutting fluids as a goodmetalworking fluid.

  • investigation on frictional wear of single crystal diamond against Ferrous Metals
    International Journal of Refractory Metals & Hard Materials, 2013
    Co-Authors: Lai Zou, Guojun Dong, Ming Zhou
    Abstract:

    Abstract It is well known that severe tool wear prevents diamond from cutting of Ferrous Metals. This paper presents a series of frictional wear experiments between diamond and steels in air ambient, to imitate the tool wear process in practical diamond cutting operation of Ferrous Metals. The wear morphology of workpiece surface was detected by scanning electron microscopy. Energy dispersive X-ray analysis was used to investigate the change in chemical composition of the work sample before and after the tests. Raman scattering analysis was performed to distinguish the transformation of crystal structure of the diamond specimens, simultaneously, the graphitized degree of diamond specimen was proposed as a criterion for assessing tool wear in orthogonal experiments. The experimental results revealed that the wear of diamond relies heavily on mechanical force and temperature, and the sliding speed and the carbon content of the workpiece materials exert relatively less effect on the diamond wear under the test condition. Moreover, tool wear mechanism was discussed based on the experimental results for the sake of expanding the application areas of ultra-precision diamond cutting.

  • Numerical Simulation on Diffusion Wear of Diamond Tool in Cutting of Ferrous Metals
    Advanced Materials Research, 2012
    Co-Authors: Ming Zhou, Lai Zou
    Abstract:

    The details of the process with respect to tool wear mechanisms in diamond cutting of Ferrous Metals are still not clear. For the sake of further studying on diffusion wear of diamond tool, as a consequence, the numerical simulation of diffusion process at interface of diamond and workpiece is presented based on Fick’s second law in this paper. The diffusion model of carbon atoms diffusion into γ-Fe has been established in terms of materials science theory. In addition, the distribution of carbon atoms concentration in regard to the variable of diffusion distance and diffusion time is calculated by numerical simulation, the tendency of concentration distribution is consistent with the results of previous studies. This work provides a basis research for diffusion wear in diamond cutting of Ferrous Metals.

  • the effects of ball and roller burnishing on the surface roughness and hardness of some non Ferrous Metals
    Journal of Materials Processing Technology, 1997
    Co-Authors: Adel Mahmood Hassan
    Abstract:

    Simple ball- and roller-burnishing tools were used for the experimental work of the present study, these tools being quite similar in their design principles. The performance of the tools, together with the effects of the burnishing force and the number of burnishing tool passes on the surface roughness and surface hardness of commercially available aluminum and brass, were studied. The results show that improvements in the surface roughness and increases in the surface hardness were achieved by the application of both ball burnishing and roller burnishing with the non-Ferrous Metals under consideration.

  • influence of burnishing process on surface roughness hardness and microstructure of some non Ferrous Metals
    Wear, 1996
    Co-Authors: Adel Mahmood Hassan, Aiman Sharef Albsharat
    Abstract:

    Burnishing is a cold working process, which easily produces a smooth and work-hardened surface by plastic deformation of surface irregularities. In the present work, the influence of the main burnishing parameters (speed, feed, force, number of tool passes, and ball diameter) on the surface roughness and the hardness of two different non-Ferrous Metals were studied. Furthermore, subsurface hardness and microstructure under specific conditions were also studied. It was found that the burnishing forces and the number of tool passes are the most pronounced parameters, which have great effects on the workpiece's surface during the burnishing process. A simple, inexpensive and newly designed ball-burnishing tool, with interchangeable adapter for using different ball diameters, was used throughout the experimental work presented in this paper.
