Abstract: This study investigates the turning machinability of cast aluminum alloy composites reinforced with rice husk Biocoke (BIC) to evaluate its potential as a sustainable alternative to conventional reinforcements such as carbon fibers.BIC was carbonized at temperatures between 643 K and 973 K and infiltrated with the aluminum alloy melt by the squeeze casting to fabricate the composites.Cutting tests using cemented carbide (H1) and polycrystalline diamond (PCD) tools were performed and demonstrated that the reinforcement with the BIC significantly reduced the cutting forces and surface roughness of the alloy.Notably, the composites exhibited the machinability exceeding that of PAN-based carbon fiber composites, particularly using the PCD tools.These results are attributed to the solid lubrication effect of carbon in the BIC.Consequently, the BIC composites can offer a lowcost, eco-friendly solution for machinable lightweight materials.
