Study on the Machinability of Two Different Sulfur Free Cutting Steels
Research has been done on microstructure and machinability of two different free-cutting steels by using cutting tools coated and uncoated at the condition of different cutting parameters. The cutting force, surface quality, chip morphology and tool wear are investigated, which reveal the influence of the size and shape of sulphide inclusion on machinability. The experiment shows that the shape of spindled sulphide inclusion has relatively better machinability than stripped sulphide inclusion and the size of sulphide inclusion also plays some influence.
