document: Application of an internally consistent material model to determine the effect of tool edge geometry in orthogonal machining It is well known that the edge geometry of a cutting tool affects the forces measured in metal cutting . Two experimental methods have been suggested in the past to extract the ploughing -LRB- non-cutting -RRB- component from the total measured force : -LRB- 1 -RRB- the extrapolation approach , and -LRB- 2 -RRB- the dwell force technique . This study reports the behavior of zinc during orthogonal machining using tools of controlled edge radius . Applications of both the extrapolation and dwell approaches show that neither produces an analysis that yields a material response consistent with the known behavior of zinc . Further analysis shows that the edge geometry modifies the shear zone of the material and thereby modifies the forces . When analyzed this way , the measured force data yield the expected material response without requiring recourse to an additional ploughing component
