Significance Of Slip Line Field Model In Accommodating All Machining Complex Behaviour

Abstract

Abstract Slip line field theory of predicting failure mechanism by estimating a feasible region of stability of stresses between two curved lines separated by an angle, gives a more systematic way of modelling for the material flow nature at the points of singularity in the plastic-friction deformation zones. Recent trends in modelling of the slip line field also incorporates the presence of a stagnation region at the tool tip which ultimately give us a hint of the shape and size of the build up edge and Build up layer (BUE/BUL). This region can be modified by altering the slip field dimensions and positions making it a flexible system, at the same time which is satisfied by all governing dynamic equations and input parameters. Though the gradual increase in the size of the BUE during chip flow and then breaking up into fragments to form abrasives are yet to be simulated perfectly in compliance with experimental observations, still slip line field theory proves to be a potential contender in accommodating all other recent machining models which ultimately brings in robustness into it and a future possibility of adding a time varying nature to all field lines satisfied by these accommodated models. In the context of all the singular regions, the recent modelling works have been explained and how slip line field theory manages to fit into defining each region
