The tools of a multiple-tool system are selected by turning the C axis. A
tool is selected by placing it at the tool reference position. This position
is parallel to the Y axis and on the center line of the tool holder of a
multiple-tool system.
For each tool in a multiple-tool system, the angle the tool makes with the
tool reference position is set in tool registering screen for. When the T
code of a multiple-tool system is issued, the CNC system sends an internal
command to the C axis, indicating the angle with the tool reference
position corresponding to the selected tool. The CNC system places the
selected tool in the tool reference position.
