Abstract
The principle of CNC machine is worldwide-applied principle in different fields
especially industry, but we saw that also graphical tools are growing fast, such
as 3D printers and 2D drawing machines, so we tried to work on an idea related
to this development. Since everyone these days tries to use anything easier, our
project is a CNC machine that takes words by voice recognition module to write
it on a paper, or a word to draw a shape on the paper. The main features of our
project will be A4988 Driver, servomotor, Stepper motors, Arduino Uno, raspberry
pi and voice recognition module. The projects works simply as following, the voice
recognition module listens to the word that we say it nearly to the voice recognition
microphone, then it sends it to the first Arduino using serial with baud rate (9600),
then the Arduino sends it to the raspberry pi using serial with baud rate (115200),
after that we have the word that has been said on the raspberry, there is files
with Gcode extension that are saved on the raspberry so each word has an file for
it, G code is nothing but a language in which people tell computerized machine
tools ‘How to make something’. The How is defined by instructions on where to
move and how fast to move. then Gcode has a commands as a vectors and it sends
them to the second Arduino which has GRBL library and connected to the stepper
motors so the GRBL send these vectors as a steps to the stepper motors which
represents the movement of the project, so all you have to do is to speak.
