Acu-Rite CNC 3500i user manual Radius compensation Machining corners

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.
