Design and Fabrication of a CNC Router Machine for Wood Engraving

Abstract The purpose of this research was to designing and fabrication a Computer Numerical Control (CNC) based router machine for wood engraving machine. The idea behind this research was to help the traditional woods craft men in Bali to make a craft more productive and more efficient. The router machine that is made is driven by the driver in the form of a stepper motor, with a 3 axis motion so that the results of wood engraving obtained are precision and homogeneous. G-code program used on CAM processing uses MACH 3 software. The workspace of the machine was 800 mm x 500 mm. The stepper motor driven with TB 6600 driver and combined with ball screw on linear bearing to make the motion more precisely. The test result showed that the machine accuracy is about 99.5 percent for X and Y axis and 96 percent for Z axis.
