SHAPING TECHNOLOGY

Rogov V. A., Kokarev V. I., Velis A. K. — Research of the sintegran processing by carbide drills

The paper presents the experimental results of researches done, to establish the relationship of processing parameters with mechanical characteristics when drilling holes on synthetic granite (sintegran) with carbide drills at Moscow State Technological University "STANKIN" with the use of the CNC machining center, based on a milling machine 24K40SF4, equipped with the system FlexNC-70 software from the company "STANKOTSENTR". This program environment allows to record the torque and axial force in real time. The research process was conducted in two stages, varying input parameters affecting the technical characteristics of the CNC machining center. The first stage was carried out at constant axial feed (at two levels), while we varied the cutting speed. The second phase was carried out at constant cutting speed (at two levels), while we varied the values of axial feed, Graphics were plotted with the mechanical characteristics obtained in real-time.

One of the main factors leading to a decrease of the original product accuracy at their utilization, is uncontrolled relaxation of residual stresses that inevitably arise in accordance with the creeping theory laws. In this paper an effective technology of the residual stresses ultrasonic relaxation in parts such as rings is considered. This technology essence is that the workpiece is exposed to elastic deformation by a certain amount. The special ultrasonic facility superimposes ultrasonic vibration by means of additional contact method. In such a case more efficient reduction of residual stress and less detail deformation during the relaxation and its original geometric shape preservation are provided.

Belousov V. P., Dianova N. G. — Stress relaxation at continuously varying cross-section

The stress relaxation on the rods with a continuously varying cross-section is considered. Relaxation is characterized by a sharp stress drop at the process beginning. There are known dependencies between strains and stresses. Numerical relationship is obtained at known relaxation kernel R(t – τ), and for the constants specific values, which shows that the rod destruction time is determined from the condition σ(tp) = σB. Thus, received results indicate that the stress relaxation at continuous reduction of the cross-sectional area is observed only at the process beginning, and the opposite occurs subsequently, i. e. the stress increase to the natural sample destruction.
