Summary:Title screen
In this paper, a stressed state of a non-worn cutting wedge in a machined titanium alloy (Ti[6]Al[2]Mo[2]Cr) is analyzed. The distribution of contact loads on the face of a cutting tool was obtained experimentally with the use of a 'split cutting tool'. Calculation of internal stresses in the indexable insert made from cemented carbide (WC8Co) was carried out with the help of ANSYS 14.0 software. Investigations showed that a small thickness of the cutting insert leads to extremely high compressive stresses near the cutting edge, stresses that exceed the ultimate compressive strength of cemented carbide. The face and the base of the insert experience high tensile stresses, which approach the ultimate tensile strength of cemented carbide and increase a probability of cutting insert destruction. If the thickness of the cutting insert is bigger than 5 mm, compressive stresses near the cutting edge decrease, and tensile stresses on the face and base decrease to zero. The dependences of the greatest normal and tangential stresses on thickness of the cutting insert were found.
