Abstract:
Due to the rapid growth of technology the usage & utilization of CNC
industries are increased. The fabrication of low
machine in
cost CNC machine is used to reduce
paper deals with the engraving of automatic
engraving and drilling. The Idea behind our project is to
on low cost CNC system the lower cost is achieved by incorporating features of PC with CNC controller card. We have use an G code for
whole system operation 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 & how fast to move. Key Words: CNC, CNC card,
motor drivers, stepper motors, power supply, spindle.
The drawings shall be generated on standard platforms with fixed limits. The
application software analyses the drawing, which then extracts the coordinates and
cost and complexity of machine. This
CNC machine for PCB
engrave and drill PCB based
sends in the form of specific command 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.
