Radius compensation: Machining corners
Outside corners:
If you program radius compensation, the control moves the
tool around outside corners on a transitional arc. If necessary,
the control reduces the feed rate at outside corners to reduce
machine stress, for example at very great changes of direction
Inside corners:
The control 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 workpiece at the inside corners. The permissible tool
radius, therefore, is limited by the geometry of the programmed
contour.
NOTICE
Danger of collision!
The control needs safe positions for contour approach and
departure. These positions must enable the control to perform
compensating movements when radius compensation is
activated and deactivated. Incorrect positions can lead to contour
damage. Danger of collision during machining!
Program safe approach and departure positions at a sufficient
distance from the contour
Consider the tool radius
Consider the approach strategy
