One of the promising methods of improving the wear resistance and reliability of the instrument are the methods of electro-physical processing. Treatment by impulse electric current on a layer of paste from dispersed materials allows to receive coatings from a deposited layer of a given chemical composition with high quality of the surface layer. In developing the equipment for the implementation of pulsed electro physical processing, there are high requirements for compliance with the processing parameters. It matters the energy and power of the electric impulse. It is from the chemical composition of the paste of dispersed materials and these energy parameters depends on the wear resistance of the coating layer obtained on the surface of the tool. The process does not require high energy costs. Among the disadvantages of this method is the need to improve the management of electrical discharge parameters. The work is devoted to the improvement of equipment for electro physical processing. The tasks are to develop a pulse electro physical processing unit and software that provides precise control and compliance with the electrical pulse parameters for controlling operating modes. The device for impulse electro physical processing and software is developed, which provides precise control and observance of the parameters of the electric pulse for control of operating modes. As part of this installation, there are two functional parts of the power and controlling logic, through which the algorithm of the system is implemented. In the developed program implemented algorithms for selecting the mode of operation of the installation, control of the entered values, pulse generation, determination of power and pulse energy. The program is created in the programming language C in the Keil u Vision 5 software environment. The control program is intended to enter parameters of the mode of operation of the installation and control of the entered values, pulse generating, determination of power and pulse energy. The help of the developed program implements the logic and algorithm of the system.
