5. TOOL FUNCTION (T FUNCTION)
When the CNC controls the indexing of the tool holder, the T code
shall contain a two–digit pot number from 00 to 99 as shown above.
Specify a three–or four–digit T code to use the multiple–tool system.
The first two digits are the pot number and the last two digits are the
number of the tool. When the T code is specified, a binary code signal
is sent to the machine.
1 The control numbers that the CNC uses to control the
indexing of the tool holders must be registered in the tool
registering screen. The number of parameters registered
must not exceed the number of tools controlled by indexing
2 The control numbers that the CNC uses to control the
indexing of the tool holders that are not part of the
multiple–tool system must be specified by a T code
consisting of two digits or less.
3 The tool numbers in the multiple–tool system must be set in
the tool registering screen for multiple–tool of tool
4 The number of digits used for the tool numbers in the
multiple–tool system can be changed when the option for
the tool data setting function is used.
2) Relationships between the multiple–tool system and the C axis
The tools in the multiple–tool system are selected as the C axis rotates.
When a tool is selected, it is positioned at the tool reference position.
The line passing through the tool reference position and the center
point of the tool holder is parallel to the Y axis.
Specify the angular displacement of each tool from the tool reference
position in the tool registering screen for multiple–tool. When T code
for the tool is specified, the CNC reports the angular displacement to
the C axis and tool is positioned at the reference position.
