Investigation methods. The application of computer systems is for the simulation of real production object operation with the purpose of quality and effectiveness increase in these objects control as a method of investigations consisting in operation computer imitation of a tool house equipped with plasma-generators of a glow discharge both at separate stages of processing and in the course of the whole industrial process. It will allow developing an optimum system of quality control of engineering processes for processing a wide range of tools with different profiles and tool materials in plasma-generators of a glow discharge. The essence of a modeling method consists in the development of such algorithms and programs which imitate the behavior of the tool house equipped with plasma-generators of a glow discharge its properties necessary for investigations, amount and field of technological parameter changes Investigation results. Plasma formed in consequence of explosive emission has in its structure the whole essential spectrum of ions for the formation of specified physical-mechanical properties on working surfaces of tools under strengthening. It contributes to the formation of the essential structure of bombarding ion flow with the wide range of frequencies and energy. The state and value of the layer strengthened located under an oxide film and formed at the stage of previous working operations at manufacturing tools and their working parts. This layer is characterized with the increased density of dislocations in depth and micro-crack presence not only within grains but between them. The uniformity of force impact depending upon current strength stability in a discharge and voltage upon electrodes in the plasma-generator is to be adjusted at constant pressure by the rate of technological environment pumping through a plasma-generator. Conclusions. The application of some quickly reset plasma-generators in tool production ensures work effectiveness increase of the tool house at the expense of optimization of tool machining in different engineering processes and with different time duration carrying out pre-production operations in the course of the plasma-generators operation and carrying out their charging from the automated area of waiting. The simulation algorithm developed at the formation of the automated system for control and management of effectiveness and quality in tool house work in different tool strengthening in plasma-generators of a glow discharge with stages different in character of plasma impact, duration and sequence of their realization allowed optimizing tool house equipment. The development of the automated system for control and management of effectiveness and quality of the working operation of plasma-generators of a glow discharge allowed optimizing the formation of the stage sequence with quick-acting processes during processing tools with different shape ensuring the formation of specified properties in neighboring layers which meets the requirements of automated technological environment.

The impact of the workability of an automated technological system on the effective implementation of the production program when processing tools in glow discharge plasma generators

The conditions for the hardening of tools in accordance with the author’s technological routes in the optimal time interval are considered using the functional dependence of the serviceability of plasma generators. This dependence takes into account the workability of the technical devices involved in processing the laying batch of tools in the speci ed time interval. The probability of performing the production process in the estimated time is represented by the product of the trouble-free operation of each glow discharge plasma generator involved in the nishing processing of tools that require a different type of plasma exposure in a certain sequence and duration.

The influence of the automation level of glow discharge plasma generators on the effective use of their technical capabilities for strengthening tools

The conditions for increasing the efficiency of using the technical capabilities of glow discharge plasma generators, depending on the level of their automation, are considered. A dependence with a variable share of costs in the form of automation parameters and rationality is obtained, which allows us to evaluate the operating conditions of an automated system for pumping sets of combined-cycle gas media with reference to automation conditions. The ratio of downtime associated with failures in the automated system of pumping combined-cycle gas media to the corresponding planned indicators is a simple and convenient indicator for assessing the optimality of the conditions for stabilizing the occurrence of downtime and vehicle shutdowns. An algorithm for solving the problem of forming a minimum nomenclature of sets of steam-gas media and the selection of their chemical compositions for technological transitions when processing tools of complex shape and consisting of working parts of different materials is proposed.
