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.
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 the tool length compensation is
changed.
Example: When the state parameter No.004 Bit4 is set to 0 and X tool length compensation
value is 10mm, the external diameter of workpiece is 10mm; when No. 004 is set to 1 and X tool
length compensation value is 10mm, the external diameter of workpiec is 20mm. Fig.2-5 is the course
of creating, executing and canceling tool offset in traverse mode.
