Introduction
to CNC Routers
(page
2 of 2)
Now lets look
at the big picture. If you could draw a picture in your mind, you
would see the following parts.
- A cad/cam
program where you create the picture (geometry) of the part that
you want to machine (2D or 3D). The cad/cam program would output
a tool path file. Most likely it would be on a diskette or
connected to your network.
- The file would
then be taken to your controller PC. Once
the controller program is loaded it can read the tool path file.
If your cnc router is powered up an running, the controller is then
ready to start sending signals (step and direction) to the stepper
motor or servo motor drivers.
- The motor
drivers in turn send the proper signal to the motors which
cause the motors to move in the proper directions.
- The motors
are attached to the lead screws which in turn move
the X, Y and Z axis.
