Abstract:            The present investigation is aimed to study how the machineability of an (Al-Fe) alloy will be affected by adding together Boron and Copper. Machineability was defined regarding a tool life based on the flank wear of  a twist drill made of high speed steel. Two percentages of copper and of boron were added together. The alloy had been prepared by casting with rapid cooling. The results showed that copper and boron have a noticeable effect on the machineability of (Al-Fe) alloy regarding the tool life, and the tool life depends on the weight percentage of the added elements, so as a smaller percentage of boron gives a tool a shorter life. A reliable model had been developed for tool life. The model took into account the effect of cutting speed, feed rate, the percentage of adding elements and the hardness of the produced alloys. This model may be utilized to enhance the efficiency of machining (Al-Fe) alloys to which elements may be added and the present method of modeling represents a suitable methodology to study the effect of additives on the machineability of the alloys.
