Restrictions of inside corner selection

• The programmed contour must be closed.
• The last motion block may not be a full circle.
• The first motion block must be a linear block; this also applies to the first motion block after TRC is deselected.
• The point P1 must at least have the distance of the tool radius to all contour elements.
• The first motion block may not cross a contour element, with the exception of the first and the last motion blocks.
• It is not permitted to change the selection side in selected state.
• It is not permitted to make changes to the tool radius of tool in selected state.
• The selection side of the TRC must be selected from the position of selection soy that the tool does not cross the programmed contour.
• The enclosed angle of the first and the second motion blocks after selection may not exceed 180°.

Causes of angle restriction:

In the above graphic, the TRC should be selected to the right of the contour. As of a transition angle of over 180° between the last and the first contour blocks, the first point of the equidistant path is determined using the direct selection method. This is P3. The diagram illustrates that the direct connection P1 to P3 violates the contour marked in red.

The angle shown as the starting angle in the graphic may be maximum 180° in order not to damage the contour. The alternative point of selection P1* prevents contour damage.

Attention

If one of the restrictions is violated, an error is output.
