The effect of machining parameters on surface integrity of aluminium material using lathe machine / Fakhrul Adam Fazilan

This project purpose is to observe surface integrity of aluminium with combination of certain speed cut,depth of cut and feed rate. In addition, this project involve with lathe machine The performance of a traditional lathe machine is nearly entirely determined by how quickly it cuts the workpiece; the faster the material is turned, the more finished products may be produced in a given amount of time. The machine's productivity is very high. High productivity requires a high rate of metal removal, lowering manufacturing costs and reducing operation time. Although a faster process is required, it does not ensure product quality in surface. This project looks into the relationship between machining parameters on aluminium material that can effect surface surface integrity. Constant cutting speed, three values of depth of cut, and four values of feed rate, three parameters were chosen. The objectives of this project is to see how machining parameters like depth of cut, cutting speed, and feed rate affect surface integrity. Next, the parameters that affect on surface finish and cutting force were studied. The surface integrity then will be observed using metallography method under the optical microscope for detailed and clear image. Based on observation that just done before, we can obtain expected result which is low surface roughness.
