Abstract
The present investigation is concerned with a class of slip-line field solu tions for metal machining involving chip curl. The solutions under consider ation were first proposed by Kudo, who had found them to be statically inad missible. In this study, these fields are analysed by assuming an elastic c ontact zone beyond the plastically stressed region. Force and moment equili brium of the chip is realised by assuming the rigid chip to be acted upon b y prescribed normal and shear forces in the elastic zone and by forces in t he rigid-plastic boundary. Results are presented for variation in contact l ength, cutting force and thrust force, with Variation in rake angle and int erface friction conditions, both for power-law and exponential pressure dis tributions in the elastic contact zone.
