2.3 Tool Function
2.3.1 Tool control
T functions ofTAC-1002T: automatic tool change and executing tool offset. Control logic of
automatic tool change is executed by PLC and tool offset is executed by NC.
Command format:
Command function: The automatic tool post rotates to the target tool number and the tool
offset of tool offset number commanded is executed. The tool offset number can be the
same as the tool number, and also cannot be the same as it, namely, one tool can
corresponds to many tool offset numbers. After executing tool offset and then T□□00, the
system reversely offset the current tool offset and the system its operation mode from the
executed tool length compensation into the non-compensation, which course is called the
canceling tool offset, called canceling tool compensation. When the system is switched on,
the tool offset number and the tool offset number displayed by T command is the state
before the system is switched off.
Only one T command is in a block, otherwise the system alarms.
Toolsetting is executed to gain the position offset data before machining (called tool
offset), and the system automatically executes the tool offset after executing T command
when programs are running. Only edit programs for each tool according to part drawing
instead of relative position of each tool in the machine coordinate system. If there is error
caused by the wearing of tool, directly modify the tool offset according to the dimension
offset.
Tool offset number（00-32，the leading zero cannot be omitted）

Fig.2-6 tool offset
The tool offset is used for the programming. The offset corresponding to the tool offset
number in T command is added or subtracted on the end point of each block. Tool offset
in X direction in diameter or radius is set by No.004 Bit4. For tool offset in diameter or
radius in X direction, the external diameter is changed along with diameter or radius when
