10. TOOL FUNCTIONS
NC FUNCTION
67
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 on the tool registered screen. 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.
