High-tech technologies for the improvement of the productivity and reliability of mechanical engineering products

Economics evaluation method of high-tech technologies application for part process of various purpose made of hard-to-machone steel or alloys at machine-building enterprises is presented. It is shown that the overall economic effect of using high-tech technologies in production processes consists of direct and additional effects. Direct benefits can be obtained by optimizing the modes and changing the conditions of machining parts, increasing the durability of the used metal-cutting tool and improving the manufacturing system as a whole by increasing its reliability and vibration resistance. To achieve direct benefits, it is proposed to use iodine-containing agents in the machining parts processing procedure and metal-cutting tool sharpening, as well as the supply of cooled ionized air both to the contact zone of the tool and the surface of the part. Additive effect can be obtained both by improving the quality of the machined surface of the part, and by perfecting organizational and technological measures during repair work, maintenance and routine maintenance within the operation of mechanical engineering products. The main components of the additive economic effect are viewed and the technique for their determination is given. Based on the analysis of the developed technique for the economics evaluation for high-tech technologies in part process together with its testing at a number of machine-building enterprises, the authors prove that its use provides calculated data comparable to the actual benefits, and can be applied in any type of production, including machine maintenance.
