In this presentation, the salient aspects specific to turning of a novel aluminium alloy metal matrix composite on a lathe machine (Type: HMT) will be highlighted. The engineered composite is an aluminum-4.5% copper alloy that is reinforced with titanium diboride (TiB2) particulates. The influence of machining parameters, to include cutting speed, depth of cut, and feed rate, on machining characteristics, namely surface roughness and cutting force will be elaborated upon. To understand the microscopic mechanisms governing the turning operation, a three-dimensional finite element simulation model was developed and used with the prime objective of estimating the cutting force. The Johnson-Cook material and failure model was used for the chosen composite material. In this research study, the cutting forces were estimated through both turning experiments and numerical simulation modelling on the chosen Al-4.5% Cu/TiB2/3p composite. Conclusions are drawn from the results obtained by use of the two methods.
