ABSTRACT
The term machinability refers to the ease with which a metal can be machined to an acceptable surface finish. Materials with good machinability require little power to remove material, achieve cutting at high speed, easily obtain a good finish, and do not cause tool wear. The factors that typically improve a material’s performance often degrade its machinability. Therefore, to machine parts economically, engineers are challenged to find ways to improve machinability without harming performance. Machinability can be difficult to predict because machining has so many variables.
