Turn the motor the opposite way and the table moves toward the motor.Īll CNC programming is a series of motions, one after the other, or all at once. Turn the motor one way and the table of the machine moves away from the motor. The motors are usually turning screws but sometimes they are turning belts or even chains. The programmer uses some form of software to program the machine to engage those motors. In most milling machines the left and right are the “X” axis, toward and away are the “Y” axis, and up and down is the “Z” axis. We call the direction of movement in a machine its axis.Ĭommonly, CNC mills have 3 axis. Nearly all CNC machines use electric motors to move the machine’s components around.
