Design of Voice Controlled Multifunctional Computer Numerical Control (CNC) Machine

The CNC (Computer Numerical Control) machine is an advanced technology that has an automated system that controls multiple machine tools using a computer. Computer Numerical Control revolutionized manufacturing, or it’s apt to say that it has taken manufacturing to a new phase. This work presents the demonstration of a low-cost Human Machine Interface for a 3- axis CNC machine. The Work that seemed impossible and took a lot of time to complete now can be accomplished with minimal effort quick and accurate manner, and as it is computerized the margin of error is diminished. The programming language for CNCs is done using G-code. Our paper focuses on fabricating a desktop-size CNC machine using the X, Y, and Z axes for performing/carrying out various functions like drawing and light-duty cutting for PCB using a microcontroller. The machine is fabricated and tested experimentally to enhance its working, robustness, and accuracy in diverse conditions. By utilizing the advanced voice-controlled CNC, the proposed study has cut down the time consumed for these processes. The input is given using software or voice control components. The methods involve the unrestricted Domain for analyzing and recognizing input.
