Abstract:
The objective of the project is to design and fabricate a computer controlled wood
engraving and cutting machine for optimized wood cutting to achieve cost
effectiveness and maintain the required accuracy and reliability for complex shapes.
Wood routing and cutting is an electromechanical process in which a drill is used to
cut or engrave the wood and its directions are controlled by the computer. Such
cutting machines are generally classified into two categories, namely, large scale
(fixed) and small scale (portable) machines. The target is to develop a small scale
setup with limited cutting size.
The drawings shall be generated on standard platforms with fixed limits. The
application software analyses the drawing, which then extracts the coordinates and
sends in the form of specific command to the embedded system through the
serial/USB port.
The system then controls the stepper motors to achieve the required movement and
the desired position. Gantry type arrangement is used to assist motors for movement
in X,Y and Z direction (3-Dimensional).
The backbone of the system is a cleverly designed but equally simple mechanical
assembly, resulting in great accuracy.
The project includes significant study of design principles and technical details of the
CNC machine aimed for best performance.
