A computer numerically-controlled (CNC) router is a machine that can create objects from wood and to any nonferrous metals. This study presents the development of a low-cost controller for the 3-axis CNC router machine. The controller unit is considered to be the heart of any CNC systems. It provides a link between the computer and drivers for motors. The developed controller is capable of digitally-controlling the mechanical motion of the three (3) axes (X, Y and Z) and the output of the 2.2-kW spindle motor. This includes the use of a digital signal processing (DSP) based motion controller board for X, Y and Z axes and the variable frequency drive (VFD) for the spindle. The controller was tested, both functionality and performance, by running different CAD programs in the CNC router. TAP extension file was the format used for the g-code toolpath of the CNC router machine. © 2017 American Scientific Publishers All rights reserved.
