  • Lapping Plate
    Lapping Plate 05M20.20 Patent Pending Lapping is the process of rubbing two surfaces together with an abrasive and a lubricant to improve the quality of at least one of the surfaces. Although lapping can be used to create fl at surfaces, in the context of woodworking, lapping better serves to minimize the roughness of a surface – known as surface conditioning. By minimizing the roughness in the sole of a plane, there is reduced friction between the plane and the workpiece, which in turn reduces abrasion. For blades or chisels, the cutting edge can be made sharper if both intersecting surfaces are free of scratches, even if the back of the blade isn’t perfectly fl at. Straight cutting edge on a lapped blade. Jagged cutting edge on a ground blade. Figure 1: A ground blade versus a lapped blade. Lapping can remove only small amounts of material. If the sole of your plane or the back of your blade is twisted, wavy or bowed, it will be necessary to sand or grind off the high points prior to lapping. Lapping is always performed with an abrasive oil slurry, which not only allows the object to slide Small Abrasive about the lapping plate (called a lap), but also Particles provides a means to remove abraded particles and worn abrasive. Oil Object Abraded Metal Lap Groove in Lap Large Abrasive Particles Figure 2: Lapping mechanics. 2 Important Notes The lapping plate is made of soft iron and will wear over time. These instructions provide information on how to ensure the lap remains fl at for a lifetime.

  • An Example from Copper and Bronze Age South-East Iberia
    Lithic perspectives on metallurgy: an example from Copper and Bronze Age South-East Iberia Selina Delgado Raack and Roberto Risch Departament de Prehistòria, Universitat Autònoma de Barcelona, Spain To the memory of Volker Pingel Summary. One of the centres of early development of metallurgy is the South-East of the Iberian Peninsula, where it played a key role in the formation of the so called Los Millares and El Argar “cultures” during the 3rd and first half of the 2nd millennium BC. Yet, most arguments about the importance of metalworking are derived from the funerary evidence, i.e. from the finished objects used as grave goods, while direct evidence of the production processes is still scant. During the last years systematic analyses have been carried out in South-East Iberia concerning the (macro-) lithic artefacts coming from a series of Copper and Bronze Age settlements and necropolis. The observation of features and traces related to metalworking on some of these labour instruments has allowed to identify the final stages of metallurgical production, as well as to the maintenance of metal artefacts. The functional analysis of these tools and their spatial distribution at a regional as well as local scale reveals important aspects of the social organisation of the process of metal production. Finally, the different technical situations are evaluated in order to understand the changing relationship between metallurgy and the emergence of new forms of domination and exploitation. Résumé. Un des centres les plus anciens de développement de la métallurgie est le sudest de la péninsule ibérique, où cette technologie a joué un rôle crucial pour la formation des « cultures » de Los Millares et El Argar, pendant le III millénaire et la première moitié du II millénaire BC.

  • Compoforging of Al-Si Metal Matrix Composites Reinforced with -Sic: an Alternative Technique
    The Open Industrial & Manufacturing Engineering Journal, 2010, 3, 1-6 1 Open Access Compoforging of Al-Si Metal Matrix Composites Reinforced with -SiC: An Alternative Technique M. F. Valencia García1,*, H. V. Martínez2 and A. Morales Ortiz2 1Escuela de Ingeniería de Antioquia; Grupo Productividad hacia la Competitividad GPC – A.A. 7516 Medellín, Colombia 2Universidad Pontificia Bolivariana; Facultad de Ingeniería Mecánica. Grupo de Investigación sobre Nuevos Materiales GINUMA – A.A. 56006 Medellín, Colombia Abstract: This paper reports the -SiC particles surface modification by copper Electroless Plating (EP), as well as a morphological characterization of Al-Si reinforced composite obtained with such modified particles and consolidated by compoforging. The -SiC particles were obtained by thermal degradation of organic waste. The compoforging technique is a hybrid between the compocasting process and semi-solid forging. The properties of the obtained composite material derive from its globular structure, which is achieved by mixing the semi-solid alloy and the reinforcing particles. This method produced an almost perfect distribution of the reinforce particles. Furthermore, it is possible to achieve minimum defects (i.e. porosity) by applying pressures up to 60MPa. Keywords: Silicon carbide, electroless plating, superficial modification, mechanical mixing, compoforging. INTRODUCTION Table 1.
