The basic idea is to find the parameters, which clearly reflect the machinability of steel. Then the parameters can be easily implemented to evaluate the machinability of steel without sophisticated apparatus. The results show that for the same cutting condition less cutting forces stand for better machinability. Less wear rate of tool means better machinability. The machined chips can also be used to judge the machinability of steel. The machined chips of free cutting steel are piecemeal while those of medium carbon steel are continuous. The curly, continuous chips are also more prone to interfere with the machining process and affect the surface quality of the machined part, and increase the wear rate of tool.

The results show that for the same cutting condition less cutting forces stand for better machinability. Less wear rate of tool means better machinability. The machined chips can also be used to judge the machinability of steel. The machined chips of free cutting steel are piecemeal while those of medium carbon steel are continuous.
