Kulik G. The optimization of technology frictional cutting of round steel pipes with rotation

Technological process of frictional cutting of round steel billets with rotation. The optimization of the frictional cutting technology of round billets at their rotation for wider use of this productive and economic process. The theoretical researches of the thermal phenomena were carried out on the basis of the heat conduction equations solution with the use of the of sources. Density of a thermal flow were is received from experimental measurement of temperature outside of the contact zone. Energyforce researches are based on the measurement of the cutting capacity. The theoretical solution of the constancy problem of a frictional disk is based on the variational method according to Ritz-Timoshenko. The optimization of process was carried out by the method of the directed search of a minimum of the specific technological cost price of cutting under the restrictions on temperature of heating of a frictional disk and critical effort cutting from conditions of stability; On the basis of the study of the physical phenomena, which accompany frictional cutting of round pipes with rotation, the effective structure of technological process and optimum parameters of its realization is supplied. The technique and algorithms of the optimal parameters choice of the cutting technology of thick - and - thin walled pipes with rotation is supplied by minimization of the specific technological cost price of process with the restriction on the temperature of the disk and its stability; Integrated at the plant "Potential", effect - 60380 grv. Area - mechanical engineering, metallurgy.
