modify the tool offset according to the dimension offset.
Fig.3-5 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. X tool offset in diameter or radius
is set by No.5004 Bit1(ORC). For X tool offset in diameter or radius, the external diameter is changed
along with diameter or radius when the tool length compensation is changed.
Example: When the state parameter No.5004 Bit1 is set to 0 and X tool length compensation
value is 10mm, No.5004 Bit1 is set to 1 and X tool length compensation value is
10mm the diameter of workpiece external diameter is 20mm.
Fig. 3-6 is to create, execute and cancel the tool offset in movement mode.

There are two methods to execute the tool offset(they are set by No.5002 Bit4(LGT)):
（ 1 ） The tool length compensation is executed by the tool traversing;
（
2
）
The tool length compensation is executed by modifying the coordinates;
