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. -

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.
