E-RADIUS ( EXTERNAL RADIUS CONCAV
This mode is used to rotate concave outer radii. The X and Z axes are moved simultaneously. In
addition to round radii, elliptical radii are also possible.
This operation does not go beyond XP and ZP. For clarication, the exact route is shown below:
Pr = cutting radius
1. Tool is moved to -XP
2. Tool is being moved to the left by the Tool Corner Radius PR into the materialContour is
being traversed
3. The traverse ends at -ZP, the tool then stands beyond 0 by the amount of the cutting radius.
4. Then the reset to 0.0 or to the set resting position takes place.
The radius is dened here by the values ZP and XP:
Circular radius: XP=ZP Elliptical radius: XP≠ ZP
