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.
Fig. 2-7 Creation, execution and cancellation of tool length compensation
G01 X100 Z100 T0101; (Block 1, start to execute the tool offset)
G01 W150; (Block 2, tool offset Block 2, tool offset)
G01 U150 W100 T0100; (Block 3, canceling tool offset)
There are two methods defined by No.003 Bit4 to execute the tool length compensation:
Bit4=0: The tool length compensation is executed by the tool traversing;
Bit4=1: The tool length compensation is executed by modifying the coordinates;
Example:
