Notice
Danger of collision!
The control traverses from the current position (starting point PS) to the auxiliary point PH at the last feed rate entered. If you programmed FMAX in the last positioning block before the approach function, the control also approaches the auxiliary point PH at rapid traverse.
- Program a feed rate other than FMAX before the approach function
- The control uses the following positions when approaching and departing a contour:
- Starting point PS
- Auxiliary point PH
- First contour point PA
- Last contour point PE
- End point PN
You program the starting point PS before an approach block without radius compensation. The starting point is located outside of the contour.
For some path shapes an auxiliary point PH is necessary for approaching or departing the contour. The control calculates the auxiliary point from the information in the approach or departure blocks.
You program the first contour point PA in the approach block together with the radius compensation.
You program the last contour point PE with any path function.
The position PN is located outside of the contour and results from the information in the departure block. The departure block automatically rescinds the radius compensation.
Notice
Danger of collision!
The control does not automatically check whether collisions can occur between the tool and the workpiece. Incorrect pre-positioning and incorrect auxiliary points PH can also lead to contour damage. There is danger of collision during the approach movement!
- Program a suitable pre-position
- Check the auxiliary point PH, the sequence and the contour with the aid of the graphic simulation
