This work presents development of a prototype for the automatic engraving machine. The proposed system controlled using computer, by setting drawing for engrave. Constructed prototype consists of XYZ coordinates table (working area), where XY for position in the engraving area and Z axis for establish little driller. Arduino board has been chosen as a controller. Movements of the machine are generated by stepper motors. For the user part Processing software was used. Graphical User Interface provided for drawing the desired pattern. The controller takes the coordinates and converts them to the signals for the motors that move grind to the given position and engrave the desired drawing. Finally, device capable of etching the desired drawing that is set by the user was obtained. System is able to engrave in plates of area 21×24 cm2. Optimal algorithm for movements of two motors is presented. Simulation model was created using Proteus software. This prototype can be used for engraving different types of materials, by changing the drilling motor to appropriate one.
