Abstract: This paper argues that despite its obvious economic and technical importance, machining remains one of the least understood manufacturing operations due to low predictive ability of the machining models. Analysing the development of various models of metal cutting, the paper points out that specialist and practitioners in the field still use the obsolete single-shear plane model, a significantly inferior model by the author|s opinion. This important issue, having the greatest theoretical significance and wide practical application must be addressed in metal cutting research. This paper suggests that the first metal cutting law (Makarow|s law) should prevent more attention of specialists. It should be used in experimental studies of metal cutting and in practical optimisation of metal cutting operations. This paper emphasises that successful Finite Element Method (FEM) requires vigilance and the same visual knowledge and intuitive sense of fitness that successful researchers have always depended on when making critical conclusions.
