Title: INFLUENCE OF CUTTING SPEED ON CHIP MORPHOLOGY IN TURNING.

Subjects: High-speed machining, Machining, Steel, Carbide cutting tools
Abstract: This paper investigates, through a systematic experimental approach, the influence of cutting speed on chip morphology in the dry machining of AISI 5140 steel using carbide insert tools. The experimental results revealed a gradual transition in chip morphology, from fragmented and irregular chips at low cutting speeds to continuous chips at the highest cutting speed tested. Furthermore, the chip compression ratio decreased as cutting speed increased, indicating a reduction in plastic deformation, whereas the chip thinning ratio increased, reflecting a more uniform material flow. It was also observed that the increase in cutting speed favoured the transition from segmented to continuous chip formation under conditions of elevated temperature in the tool–chip contact zone. Overall, the results confirm the essential role of cutting speed in controlling chip formation during the dry machining of hardened steels. [ABSTRACT FROM AUTHOR]
