points in the option of workpiece boundary point, the system will determine the circle center with three points
and shield R.
The centered step of three points arc follows:
 Select the edit mode;
 Press [Coordinates], [Coordinates Parameter] to enter the auxiliary parameters setting
interface of the coordinate system;
 Move the cursor to desired position, enter new parameters and press [EOB];
 Select hand wheel or manual mode;
 Press [Coordinates] to enter coordinate system setting interface;
 Press the left/right arrow to move the cursor to select coordinate system;
 Press [Centered Measurement] to enter centered interface;
 Move the tool to make its side blade touch the surface of round workpiece, and press
[EOB] to record boundary point 1;
 Move the tool to make its side blade touch another point in the surface of the workpiece,
and press [EOB] to record boundary point 2;
 Move the tool to make its side blade touch another point in the surface of the workpiece,
and press [EOB] to record boundary point 3;
 Press [EOB] after recording all boundary points to calculate the coordinates of circle
center and display in the result section;
 If there is no question, press [EOB] again to return the result to specified coordinate
system.
