Abstract: This research deals with the determination of cutting performance of the Iraqi carbide tools with double rake geometry with negative/positive combination through the stress distribution within and at the boundaries of the tool wedge. A modification in geometry was achieved using the finite element technique by considering the cutting tool in a plane strain employing the MSC/Nastran package. An experimental work was also conducted on double rake geometry produced by grinding a negative land on the rake face. The double rake geometry was varied in primary rake angle (-10, -20 and -40°) and the land width of (0.1, 0.3, 0.5 and 0.8) of the initial carbide using optimum geometry obtained from stress analysis. The result demonstrate that at negative and positive rake geometry and at the point of zero stresses the type of stress changes from compression to tension and they are shifted away on the cutting edge leaving more space on the top of the rake cutting zone under compression.
