Description
Tool radius compensation is normally active before the compensation suppression and is still
active when the compensation suppression is deactivated again. In the last traversing block
before CUTCONON, the offset point in the block end point is approached. All following blocks
in which offset suppression is active are traversed without offset. However, they are offset by
the vector from the end point of the last offset block to its offset point. These blocks can have
any type of interpolation (linear, circular, polynomial).
The deactivation block of the offset suppression, i.e. the block that contains CUTCONOF, is
offset normally; it starts in the offset point of the start point. One linear block is inserted
between the end point of the previous block, i.e. the last programmed traversing block with
active CUTCONON, and this point.
Circular blocks for which the circle plane is perpendicular to the offset plane (vertical circles),
are treated as though they had CUTCONON programmed. This implicit activation of the offset
suppression is automatically canceled in the first traversing block that contains a traversing
motion in the offset plane and is not such a circle. Vertical circle in this sense can only occur
during circumferential milling.
