7.5.1 Offset setting
1) Press key to enter the offset setting page, select the desired window by pressing the
, ;
2) Move the cursor to the location of the tool offset, wear number to be input.
Scanning: Press , to move the cursor in sequent
Searching: use the following press keys to directly move the cursor to the input position:
Press + offset number + or and input the offset number in
the pop-up dialogue box, press and the cursor directly positions the target
offset number.
3) After pressing the address key or , the numerical number may be keyed in
(decimal point allowed);
4) Press and the CNC calculates the offset value automatically and displays the result
in the window.
7.5.2 Offset alteration
1) Refer to OPERATION, Section 7.5.1, and move the cursor to the location of the offset
number that is to be altered;
2) If the offset value of X axis is to be altered, key in U; as for that of Z axis, key in W;；
3) Then key in the incremental value;
4) Press to add the current offset value to the value keyed in, the operation result will be
displayed as a new offset value.
Example: The set X axis offset value is 5.678

253
Ⅱ Operation
The increment keyed in is U 1.5
Then the new offset value is 7.178 (=5.678+1.5)
7.5.3 Offset alteration in communication mode
For the alteration and setting of the offset value in the communication, please see Chapter
12 of
this part for its operations.
Note 1: While changing the offset value, the new offset value takes effect after the T code is
executed.
Note 2: If the actual workpiece dimensions doesn’t conforms to that of the part drawing, subtract
the error
from the original offset value for the oversize workpiece, add the error to the original offset value
for
the undersize workpiece.
Example: The external diameter of the workpiece to be machined is Ф55.382, and the
No.01 offset
value is applied in the machining. Before machining, the values in No.01 are shown as
follows table:
