1.1 Basics

Multipoint tools for the B axis

If several tools are mounted on a tool holder, this is are 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 “C” 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.

The tool magazine

The CNC PILOT supports a pocket-based tool magazine with up to 99

tools. Pocket-based means that each tool is assigned a specific pocket

in the magazine. The machine operator assigns the pockets when

setting up the magazine.

The magazine list indicates the current assignment of the tool

magazine. The tools are entered in this list with their ID numbers.

Tool programming: The magazine tools are intended for the B axis.

The command G714 is provided for changing and positioning the tools.

Alternatively, you can also use single commands (G0, G15, etc.) to

program a tilting of the B axis and a rotation of the tool to the position

angle. Please note, however, that you will need to declare the tool

position with G712 in that case.
