Electrospark deposition（ESD）can be used for preparing strengthened coatings with high hardness

excellent wear resistance and excellent corrosion resistance

which can significantly improve the performance and service life of mechanical parts. However

traditional ESD mainly relies on manual operation. In this paper

a set of ESD automatic deposition monitoring system is designed based on Labview as a development platform

and the hardware of the system is mainly composed of a PC

an Arduino control card

a stepper motor and the like. The system has the functions of motion control

motion feedback

data collection

deposition track setting

display and the like. The Bresenham algorithm is added to a deposition path

and therefore the automatic control over an ESD process is realized.
