Research of the Causes of Nickel Alloy Pipeline Failures Under Exposure to High Temperatures

Achievements of cutting materials science in Russia and abroad have been emphasized. Tooling operation specifics using a spherical milling cutter is characterized by slice thick-ness of work material burst layers located in close proximity of the axis and the cutting speed, which tends to zero. A scheme that al-lows calculating the value of the axial cutting force as an integral of the cutter bit angularity relative to the axis of the cutter from the point of origin of the burst layer to its end, is pro-posed. The calculation of the variable part of a certain integral, without taking into account the constant cutting force, was performed using the Mathcad mathematical package. To determine the ratio of the cutting force normal component to the main characteristic, the results of the work, where a special control experiment was carried out to determine the specified components of the cutting force when the burst layer thickness was changed from zero to the beginning of the stable chip separation process, were analyzed. It is found that at the beginning of the chip separation process, the main component of the cutting force rises exponentially (by 2,5 times), and the normal one does not spike.
