4.2 Tool Data
Radius compensation: Machining corners
Outside corners:
If you program radius compensation, the CNC moves the tool
around outside corners on a transitional arc. If necessary, the CNC
reduces the feed rate at outside corners to reduce machine stress,
for example at very great changes of direction.
Inside corners:
The CNC calculates the intersection of the tool center paths at inside
corners under radius compensation. From this point it then starts
the next contour element. This prevents damage to the work piece.
The permissible tool radius, therefore, is limited by the geometry of
the programmed contour.
Danger of collision!
To prevent the tool from damaging the contour, be careful
not to program the starting or end position for machining
inside corners at a corner of the contour.
