Fig. 3-8 Modifying the coordinates mode to execute the tool offset
When T code and the motion code are in the same block, they are executed simultaneously, in
executing tool change, the system executes by adding the current tool offset to coordinates of motion
code and whether the cutting feedrate or the rapid traverse speed is defined by the motion code.
Note 1: In tool traversing compensation mode, when the system executes the tool offset, NO. 5002 Bit6 (LWM)
sets the valid method of the tool offset:
LWM=0: it is valid in the block of T code
LWM=1: it is valid in the axis movement block
Note 2: No.5001 Bit6
（
EVO
）
sets the valid method of modifying tool wear tool when the system executes the
program:
EVO =0: it is valid in the next specified T code
EVO =1: it is valid in the next buffer block
Note: After the tool wear value is modified, the system executes the wear value according to
No.5002.2 setting method to avoid the too big wear value.
Note 3: It is suggested that the program should be complied according to the normative method, that is, the
tool change is executed in the safe position and then the absolute value code is used to position to the
starting point of the machining.
Note 4: In the coordinate offset compensation mode, when the system executes the tool offset and executes T
function code instead of movement code, it uses G50 to set the coordinate system, the displayed
absolute coordinate value is that the coordinate value set by G50 adds or subtracts the unexecuted
tool compensation value.
Note 5: T code can use the leading zero. When T00 □□ is executed or only tool offset number is executed in the
program and the current tool number is not changed, the system only correspondingly modifies the
current tool offset value.
