The authors have determined the economic effect of the introduction of computer-aided design systems for technological preparation processes in the machinebuilding industry.The research methodology is based on scientific heuristic methods and methods of functional analysis.The consolidated technical and economic indicators of the implementation of CAD TP were obtained, such as the average operating time of the system, the cost of CAD, capital investments, annual operating costs, the expected annual economic effect, the coefficient of economic efficiency, payback period.A methodology has been developed for calculating the economic effect from the introduction of CAD of technological processes, which differs from the methods by the lack of comparability of options for the identity of the results in the form of specific products.The author's vision of the terms of the economic effect from the introduction of CAD TP at mechanical engineering enterprises is proposed.The presented calculation method can be used in practice to determine the effectiveness of the creation and implementation of applied software products.The practical significance of the study lies in the adaptation of the software developed by the authors at machine-building enterprises.In the course of the research, the software was successfully tested and adapted, which is confirmed by the received certificates of implementation and title deeds.The duration of work during the technological preparation of those solved manually is 3.5 times longer than when working on a computer.
