applied, but the X ,U or Z ,W cannot be applied. For example, traverse the tool from A point to B
point as Fig. 3, X axis is applied with the absolute coordinates and Z axis with the incremental
coordinates as: X 5 0 W -4 0.
1.4 Workpiece Coordinate System
The workpiece coordinate system is defined that some point on the workpiece is considered as
the coordinate origin to create the coordinate system. Its axes are separately parallel with X, Z
axis in the same direction.
After the workpiece coordinates is created, all absolute coordinate values in programming are the
position values in the workpiece coordinate system. Generally, Z workpiece coordinate system is
set on the rotating centerline of workpiece.
According to the actual condition in programming, define the workpiece coordinate zero, i.e. the
programming home in the workpiece drawing and the coordinate origin of CNC system command.
The workpiece coordinate system is created by setting a workpiece coordinate.
1.5 Reference Point
The reference point set by the operator is at a safe and convenient position. Any position can be
set to the reference point but it is generally set at the safe position.
Once the reference point is defined, the tool can return to the reference point by executing the
reference point return function in “Manual” or AUTO mode. Even if the system is switched off, the
reference point still exists. If the stepper motor is employed, there is slight error caused by the
motor vibrating after the system is switched on again. Execute the reference point return again to
avoid the error.
The reference point is automatically set to X=150, Z=150 without setting the reference point after
the system is switched on firstly.
