Multipoint tools for the B axis
If several tools are mounted on a tool holder, this is referred to as a
"multipoint tool." Each cutting edge (tool) of a multipoint tool is
assigned a separate ID number and description.
The position angle, which is identified by "CW" in the figure, is
included in the tool data. When a cutting edge (tool) of a multipoint tool
is activated, the CNC PILOT will rotate the multipoint tool into the
correct position. The position is determined from the position angle, to
which the offset position angle from the tool change routine is added.
This allows inserting the tool either in the "normal" attitude or "upside
down."
The photo shows a multipoint tool with three cutting edges.
