REF datum memory function - FIND REF
Function :
In all basic functions of this DRO, such as dimension prset, zeroing, center find and etc., the DRO will
automatically store the relative distance between the
REF
mark and the work piece datum ( ABS Zero
position ), however, it is the most vital and basic that the DRO must know where the
REF
mark is located.
The REF FIND function is to let the DRO know where is the
REF
mark located.
If the operator do not
perform this function at least one time after the power up of the DRO, then the DRO don't
know where ther REF mark is located, and subsequently all the recall 0 function is totally
useless and incorrect !
Therefore,
it is a very good practise to perform the REF FIND function at least one time on
every power up of the DRO, or before any important machining
, if you have perform the REF FIND
once after the power up of the DRO, then you have no need to worry of losting your work piece datum
no matter what power failure accident happen. You are for sure the work datum will never losted.
Step 3
: move the machine across the center of the glass grating scale until the X axis digit display
start run. (
please notice that the machine move must toward the positive direction
)
only when the DRO is
now in ABS coordinate,
it can enter into the
ref function
FIND REF
( find REF mark )
RECALL 0
( recall work zero )
to select the FIND REF
( find REF mark )
Step 1
: enter into the ref function, select the
FIND REF
( find
REF
mark )
select X, Y, Z or U axis
U
or
to select all
axes respectively
select X axis
in this example
Step 2
: select the axis of which the REF mark needed to be found
move the machine until
axis display start run
move the machine across the
centre of the glass grating
scale. ( must moving towards
positive direction
, otherwise
no start count is possible )
To improve the accuracy of the REF FIND, and avoid any backlash errors caused by old or inaccuracy machines,
the REF FIND is designed to work on positive direction only
