One of the most effective ways to improve the process of teaching foreign languages for specific purposes is to use computer and Internet technologies in the education system. The computer-information model of education is a kind of transitional stage from the system of traditional methods of teaching foreign languages to the modern system of information education. The article describes the advantages and disadvantages of the most progressive and wide used technological means like computers, laptops, interactive whiteboards, tablet PCs and graphics tablets, whose implementation into the educational process can significantly increase the effectiveness of teaching foreign languages for specific purposes and help in organizing lessons. Moreover, various language learning multimedia tools such as Modular Object-Oriented Dynamic Learning Environment and digital presentations, and peculiarities of their use are highlighted. The research of experimental data has been carried out after several surveys among Tavria State Agrotechnological University students. The necessity of information technology implementation into the process of learning foreign language for specific purposes was analysed.

As a result of experimental data obtained from previous articles, it was found that for a certain material of the cutter there is a relationship between the tool life and the measured medium temperature of the cutting edge, which can be applied to most materials. This article provides a method for determining this ratio when the number of experimental results reflect the service life of the cutter and when determining the corresponding average temperature of the cutter, not using measurements, but using a recently developed calculation method. Calculation theory is applied to determine temperature using life-to-temperature relationship and to calculate tool life under a much wider variety of cutting conditions and compare these results with experimental data. The main advantage of the method over conventional empirical methods for establishing tool life, such as the method based on the well-known Taylor equation, is that the calculation can be carried out taking into account changes in cutting conditions and material properties and that the determination can accordingly be carried out according to those limits at which it is possible to confidently predict the service life of the cutter of experimental studies.
