PROCESSING MODES OF THREAD SURFACE PROFILE OF METRO CARS’ WHEELSETS
Abstract
The rationalization of recovery modes of thread surface profile of wheel sets due to the use of a criterion «optimal cutting temperature», introduced by professor A. D. Makarov is shown. The work of a tool in this mode provides its maximum dimensional stability (durability) and required speed of metal processing. This process involves similarity method, thermophysical and thermomechanical approaches, as well as a method of linear programming. It was experimentally found that using similarity method, it is possible to calculate processing modes, which not only improve the features of a cutting tool and provide satisfactory chip formation, but also extend service life of wheels of metr o cars.
