Design of a Small-sized Simple Printed Circuit Board Engraving Machine

Abstract

What this design has developed is kind of simple PCB CNC engraving machine for personal and school laboratories (hereinafter referred to as: engraving machine). According to the requirement of system design, the design scheme of main motion and feed motion of engraving machine is fully demonstrated. The system consists of mechanical part and control part. The mechanical part adopts vertical structure and calculates the design parameters according to the working requirements of the system. The control part takes PC as the control core to design the control hardware module. The open-loop servo system with simple structure, stable operation, easy control and convenient maintenance is adopted.
