Referring to extensive use of aluminum alloy (AA) 6061 in various types of industrial divisions, adequate knowledge of factors governing machinability aspects of AA 6061 under different heat treatment conditions (T6, T4, and T651) is important. This subject has received limited attention in the literature. Therefore, surface roughness, cutting force, tool wear as well as burr formation morphology, and chip shape were considered as the main machinability attributes during dry drilling tests. Under specific conditions, the bio-lubricant was used, and the obtained results were compared with those recorded under dry condition. Although heat treatment conditions may increase the hardness of the work parts, consequently higher cutting force and more built up edge were observed under dry condition. Although better machinability was observed under lubricated tests, however, due to interaction effects between cutting parameters, an adequate selection of cutting tool material and geometry as well as lubrication strategy and flow rate are of prime choice in order to improve the machinability of heat treated work parts.

提到铝合金（AA）6061在各种类型的工业部门中的广泛使用，重要的知识是在不同的热处理条件（T6，T4和T651）下控制AA ​​6061的可加工性方面的因素。该主题在文献中受到的关注有限。因此，在干式钻探测试中，表面粗糙度，切削力，工具磨损以及毛刺形成形态和切屑形状被认为是主要的可加工性属性。在特定条件下，使用生物润滑剂，并将获得的结果与干燥条件下记录的结果进行比较。尽管热处理条件可能会增加工件的硬度，但因此在干燥条件下观察到更高的切削力和更多的堆积边缘。
