Abstract
Given are the results of modernization of control system of A1756 machine for plasma-powder surfacing. New control system allows for complete automating of surfacing process as well as optimizing consumption of filler powder and minimizing its loss. Control of surfacing process is carried out with the help of programmer, designed using PIC16F886 (Microchip) microcontroller and alphanumeric OLED indicator WEH1601A (Winstar). Microprocessor block of the programmer allows for setting the parameters of time characteristics for surfacing current and powder consumption and their processing in process of program control. Scheme of programmer connection to A1756 machine with capability of operation switching from programmer as well as in simple design mode was developed and built. The programmer allows for carrying out setting of modes, providing good bead formation during automatic plasma-powder surfacing, quality filling of crater and minimum loss of filler powder. 2 Ref., 7 Figures.
