SECTION 3 OPERATION (OF CNC LATHE)
If the workpiece length is 100 mm (3.94 in.) when it has been cut using a tool with a tool offset of Z =
-0.500 mm (0.0197 in.), the position of the tool with a tool offset of Z = 0 is 99.5 mm (3.917 in.) from
the reference point (program zero).
A procedure that does not require a modification of the set zero offset value is described below.
Procedure :
1-
Carry out steps
“1-”
and
“2-”
as explained before.
2-
Enter tool offset data to tool offset #1 register.
(Refer to “Setting Tool Offset” in “Data Operation” of OSP Operation Manual.)
3-
Cut the end face of the part by moving only the X-axis in the MDI mode with T01 (Tool No.)
01 (Tool offset No.) active.
(Refer to “Manual Data Input (MDI) Operation” in “Operation” of OSP Operation Manual.)
4-
Carry out steps
“3-”
through
“10-”
as explained before.
With the procedure above, it is not necessary to modify the set zero offset value by taking the
tool offset value into consideration.
[Supplement]
Never reset the control after cutting the part in the MDI mode.
