When automatic and manual return to refer–
ence point functions are not used
To set up the programmed work coordinate
system with workpiece as a basis without
using the reference point, proceed as
follows :
Select the reference tool and set the test
workpiece.
Position the Z-axis at the workpiece face
(reference surface) by manual operation.
Reset the current position display of Z-axis.
Then Z-axis is determined as Z–axis coordi–
nate point.
Position the X-axis at the outer surface of
the workpiece by manual operation.
Then the control executes cutting outer
surface if necessary.
Turn on MACHINE LOCK and set the dimen-
sions of the work outer surface as the cur-
rent position display of the X–axis.
Then the center is determined as X-axis
coordinate point.
Turn off MACHINE LOCK.
Move the tool to the setup point for each
axis, checking against the current position
display.
When the operations mentioned above are
proceeded correctly, tool position offset
amount for the tool will be zero.
