Abstract
The strip peeling of carbon steels at high speeds has been successfully modelled on a lathe by turning tube with tension applied to the chip. Tension stresses up to approximately the shear flow stress of the chip material have been applied to the chip before it broke. Chip thickness to feed ratios have been reduced to between 1. 0 and 1. 5. Tool forces and the specific cutting energy have also been reduced. Tool rake angles in the range 20 to 30° are best for the process. There is advantage in pulling on the chip in a direction inclined by up to 30° away from the rake face. Quick-stop sections of the process show plastic flow to occur in two separate zones. The chip is formed curled in the chip formation zone and is later plastically straightened under combined bending and tension stresses. This observation is the basis of an analysis to be reported elsewhere.
