Abstract

The current work emphasises the impact of the various modes of cutting tool edge wear and failure on the different force components considering the three-dimension orthogonal continuous machining using multi-coated carbide tips. Edge force is usually attributed to the ploughing and rubbing actions on the tool-workpiece interface which, in turn are associated with the extent of the inevitable wear modes: nose, flank, and notch wear. Modelling of the experimental results using linear and non-linear regression analysis is established to qualitatively and quantitatively grasp the functional interrelation among the involved parameters. Results indicated that all force components are, to different extents, affected by all edge wear land modes. However, it is shown that each of the observed edge wear and failure has its own potential on specific force components and on specific cutting pressure.
