Set WCS Origin by Centering

For regular-shaped workpiece, you can use Centering function to get workpiece origins of X-axis
and Y-axis.
It includes two types of centering:
• Line Centering: Used to find the center point by two points on the workpiece. It is applicable
to regular rectangular workpiece.
• Circle Centering: Used to find the center point by three points on the workpiece. It is
applicable to circular workpiece.
For details, see NcStudio Function Manual.
To start centering (taking X-axis and line centering as an example):
1. Press corresponding mode button on operational panel to activate manual mode, including
Jog mode, Handwheel mode and Stepping mode.
Handwheel mode is suggested.
2. Press Advanced > B > T to open Center interface.
3. (Optional) Press F5 to turn on the edge finder.
In centering process, use the edge finder to position precisely. At this time, value of
parameter Spindle Speed in Centering will be used.
If the edge finder is not enabled, parameter Spindle Speed in Centering is inactive. Press
CW or CCW on operational panel to turn on the spindle. Spindle rotational speed will be the
setting value for the spindle in the software or the rotational speed specified by S command
in the program file.
4. Manually move the tool to one side of the workpiece, and press F1.
The software records the X and Y machine coordinates of the current position.
5. Manually move the tool to the other side of the workpiece, and press F2.
When X-axis is centered, the other axes should keep still.
The software calculates the middle point according to the second position and the last
recorded values, and sets it as the workpiece origin in X and Y axes.

Set WCS Origin by Clearing

When demand for accuracy is not strict enough, you can set workpiece origin by clearing.
Use Clear (also called Zeroing) to clear current workpiece coordinate of each axis, and set work
offset value as corresponding machine coordinate of each axis. Machine coordinate of each axis
remains unchanged.
To clear the workpiece coordinate and set workpiece origin:
1. Press corresponding mode button on operational panel to activate available modes.
Clear function is only used in Jog, Handwheel and Stepping modes.
2. Press State > A > F2.
Clear interface opens.
3. Do clearing on each axis.
• F1: Clear current workpiece coordinate of X-axis to zero.
• F2: Clear current workpiece coordinate of Y-axis to zero.
