This paper describes about the Fabrication of portable 3 Axis CNC router machine. The Part programming of the required design to be engraved was done with the help of image processing. The design to be engraved is created using the software (ArtCam, InkScape) which supports image processing, and then G-codes are generated and sent to the microcontroller through GRBL software using serial communication which then sends the signals to the actuators which performs the required motion on the job according to point coordinates. The feature of an offline G-Code parser interprets on the micro-controller from a USB. After testing this machine can be used for engraving, on Metals such as aluminum up to 0.4mm depth, in 2D. This machine is capable of performing machining
operations in work area of 28cmx17cm.
