CNC Vertical Machine Precise Movement Control

The CNC Machine can position X/Y/Z Axis at the accuracy of 0.001mm over the entire machining envelope. To a large degree, this precision is controlled by the the use of a closed-loop servo mechanism. The servo motor attached to X/Y/Z Axis rotate the ball screw of the axis by a movement signal which comes from the CNC Control Board. At the same time, the ball screw is fixed with the work table and spindle column, and make them move.

The actual position of the axis is continuously monitored and compared to the commanded position with feedback from a servo transmitter attached to the ball screw. Ball screws have almost no backlash, so when the servo reverses direction there is almost no lag between a commanded reversing motion and corresponding change in table direction. CNC controls employ electronic compensation to adjust for any minor backlash that may exist.

When the CNC machine runs, it doesn’t know where the axes are located and positioned in the work space.Home position is found by the Power On Restart On Restart sequence initiated by the operator by pushing a button on the machine control after turning on the control power. The Power On Restart sequence simply drives all three axes slowly towards their extreme limits (-X, +Y, +Z). As each axis reaches its mechanical limit, a microswitch is activated. This signals to the control that the home position for that axis is reached. Once all three axes have stopped moving, the machine is said to be “homed”. Machine coordinates are thereafter in relation to this home position.
