E-RADIUS ) EXTERNAL RADIUS KONVEX
This mode is used to create convex outer radii. The X and Z axes are moved simultaneously. In
addition to round radii, elliptical radii are also possible.
The cutting radius correction requires that this process is carried out beyond XP and ZP!
The exact procedure is shown below, for clarication with a round insert:
Pr = cutting radius
1. Tool is moved beyond XP by the amount of the cutting radius.
2. Tool then stands deeper than XP
3. Z is delivered, contour is traversed
4. The movement ends beyond ZP by the amount of the cutting radius.
5. Then the reset to 0.0 or to the set derivative position takes place.
With small cutting radii, the distance that must be travelled further is therefore small, but it
must be considered if at the end there is an obstacle.
Due to the cutting radius compensation, it is impor-
tant to zero the axes in this way:
