Operation
2) If the offset value of X axis is to be altered, key in U; as for that of Z axis, key in W;
alternatively, select the data position to be changed by
soft button;
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
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
Ф
55.382, and the No.01 offset
value is applied in the machining. Before machining, the values in No.01 are shown as
follows table:
No. X Z T R
00 0 0 0 0
01 16.380
-24.562 0
0
In machining, the actual external diameter measured of workpiece is
Ф
55.561, so the offset
value of No.01 can be altered as follows table:
No. X Z T R
00 0 0 0 0
01 16.201
-24.562 0
0
Note: To backup and restore the tool offset values, the relevant operations may be performed on PC via
communication.
7.5.4 Offset Values Clearing
1) Move the cursor to the offset number to be cleared;
2) When the offset value of X axis is to be cleared,
is pressed, then
is done, the
offset will be cleared. Other axis clearing is done like that;
Note: The offset clearing in the tool offset page doesn’t mean that the system in under the state with no
offsetting, if the system is needed to be in this state, the offsetting is required to be executed, which is
shown as follows:
Execute a positioning command in T0100 state or perform a machine zero return. After the offsetting is
finished, the “
