Scientific technical progress demands of technologists decision of questions concerning cardinal improvement of quality of engineering products, and also providing of breakthrough aggregation of features and their practicality measure. In particular, it is necessary for hardware which works under severe operation conditions, and to features of which great demands are made. There are a lot of different functions which affect products in operation conditions. And these functions have variable action parameters. That fact in some cases leads to quick product function loss and to reduction of operating properties of machine or technological system. So, engineering products should be provided by unconventional properties [1, 2, . In order to resolve the problems we need nontraditional approaches in development of fundamentally new technologies. They should allow solving complicated problems of new generation of machines development with properties composition, got through application of different in significance technologies [.

The flank wear rate of cutting inserts grows in proportion as the force and cutting temperature in-crease which in their turn depend on the value of bevel edge wear. It is possible to reduce the influence of a tool contact area with the work piece upon processes accelerating wear by means of changing the flank form. The paper reports the methods for the estimation of wear resistance of flanks in cutters of different forms. There is offered a new design of replaceable tangential cutting inserts with a combined form of an end flank allowing the considerable increase of a tool life without decrease of work piece quality. The results of new cutting insert manufacturing testing in rail milling operations are presented

: In this work there were developed fundamentals in parameter definition of products routing in flow-spatial technological systems which have branching flows of products. In work there have been established initial conditions for definition of parameters of products routing.In work there were considered peculiarities of operation of flow-spatial technological systems with branching flows of products. There were developed basics of definition of parameters of products routing on the basis of multidimensional algebra of groups.

Mathematical models have been developed for the surface hardening of VT20 and OT4 titanium alloys by electrospark alloying, which can be used in the design of technological processes for the manufacture of titanium blades of steam turbines.
