Open control architecture is a revolution in open source electronics which enables open architecture controller for CNC systems. This project emphasizes on proposing a design for CNC engraving machine based on open source electronics for engraving the side walls of the tyre mold. The designed engraving machine consists of 3 axis Z axis, Y axis and A axis or the rotary axis. An open source controller software known as GRBL which receives the G-codes from the CAM software is used to control the microprocessor which in turn control the machine drives. The open architectural controllers provide reliability, stability and modularity for the system. The application of open source electronic systems can provide similar accuracy and precision at an affordable budget.
