Material and Experimental Procedures

• Carbon steel Ck45 cylindrical bars were used as work material

• Longitudinal turning tests were carried out with:

• Cutting speed: 180 m/min

• Feed rate: 0.05 - 0.1 - 0.15 - 0.2 - 0.25 - 0.3 - 0.4 - 0.5 - 0.6 - 0.75 mm/rev

• Depth of cut: 0.5 - 1 - 2 - 3 mm

• Four chip form typologies were obtained according to ISO 3685
