<![CDATA[Abstract: In the process of metal cutting, cutting tools is an important factor to consider. Selection of cutting parameters and cutting tools geometry contributes to the surface condition of the resulting workpiece, especially surface roughness. The nose radius of cutting tools is a piece that rubs against the workpiece that will form a scratch to produce a flake. Various types of cutting tools angles today are developed and certainly give effect to changes in surface roughness of the workpiece and topography. To know the condition of surface workpiece produced, then conducted research influence variation tool nose radius cutting tools to roughness and topography surface workpiece. This research was conducted using CNC lathe. Three variations of end of carbide insert tip used i.e. 0.4, 0.8, and 1.2 mm are installed. Right on tool holder cutting tools. The cutting speed used is 500 m / min, depth of cut 0.2 mm, and feeding of 0.3 mm / put. Material workpiece aluminum alloy type 6061 turning without using coolant. The workpiece of the lathe result is measurement of surface roughness by using Mitutoyo surface test, and observation of workpiece surface condition done by Jenco digital microscope model BC 4-311. The result of the analysis shows that the surface roughness value is inversely proportional to the increase of nose radius cutting tools tool. The larger the nose radius cutting tools, the smaller the surface roughness. The lowest roughness value is 1.046 μm with cutting speed of 500 m / min and 1.2 mm tool nose radius cutting tools. The percentage decrease in surface roughness with the difference of nose radius cutting tools tool is 12.24%. ]]>

<![CDATA[Abstract: Many automotive components are made of Aluminum alloy. The broken or cracked components are generally replaced with a new product. For the reason of the number of component and cost, recondition is considered as a very profitable solution. So far, the recondition on this alloy component was repaired by using TIG or MIG. However, this alloy is easily oxidized and forms Aluminum oxide. In addition, the alloy is also easy to form a fine cavity and weld cracking. So, the problem to be solved in this work is how to conduct the CFC (Continuous Flow Casting) process so that the repair process produces a joining that is free from cavities and hot cracks. In this work, the objective is to repair an aluminum alloy by using the CFC method. The problem solution is performed by experimental investigation, which is the repair process using CFCs. The surface repairs result was poured by dye penetrant fluid then metallographic examination and hardness testing. From the experimental results obtained that the metallurgical bonding in the connection area is considered good because there is continuity of micro structure between the parent metal and filler metal. ]]>

<![CDATA[Abstract: In general, water vehicles or water transport commonly called canoes are still used in villages for fishermen to fish in the sea and in rivers. Aluminum alloy in this research using Aluminum series 5. Background of this research is to analyze the strength of TIG weld (Tungsten Inert Gas) connection in the canoe to get reliable samples and no leakage. In high TIG welding the low temperature is determined by the high-low of the electric current being flowed. The aluminum plate for the canoe is subjected to material composition testing and tensile testing to determine the physical and mechanical properties of the TIG welding joints on the aluminum series 5. TIG welding with the current variable 65, 70 and 75 Ampere. Testing specimens of 2mm thick with dimensions of 24x16 cm where the electric arc flame is generated by tungsten electrodes (non-feeding electrodes) with metal workpieces. Test results obtained include that welding on aluminum series 5 is done with AC current (Alternating Current) due to the action of cleaning the metal surface is greater. Thin metal work, TIG welding can be used without metal filler. Material composition test showed that aluminum content of 97,76% and magnesium main addition element equal to 1.753%. In tensile testing, the strong variations of current used to connect aluminum plates are 65, 70, and 75 Ampere produce different tensile strength. The highest tensile strength is generated on plate grafting using a strong current of 75 Ampere with a yield of 165.91 MPa. This is because with a strong current of 75 A, the welding liquid enters and fuses into the center of the aluminum, resulting in a strong welding joint. ]]>
