Shrinkage Calculation
3. Shrinkage Compensation
When the operator is familiar with the DRO's shrinkage function, instead of calculating all expanded /
reduced dimensions and marking them onto the drawings, he also can use the shrinkage compensation
feature of the DRO which expand and reduce all displayed dimensions according to the multipy or
division of the shrink factor, no need to calculate all work dimensions one by one.
Most mould makers insist that they have more confidence by calculating all shrinked dimensions in prior
to actual machining and mark those dimensions on the drawing, the DRO's shrinkage compensation
can provide a very efficient way for the mould maker to verify the calculated dimension by switching
between the actual, expanded, reduced dimensions for just only a single key press !
Shrinkage compensation KEYs : for expand calculation
for reduce calculation
Example : To compensate by Reduce, so that the DRO's
actual displayed dimension are reduced
by the ratio of the
shrink factor .
When the ES-12 is in Shrinkage Compensation
display mode, the displayed dimensions in
all axes are either "expanded" or "reduced"
by the ratio of shrink factor.
To remind the operator that the ES-12 is in
Shrinkage Compensation mode, the message
display will displaying :
1) The message of "+ SHRINK" and keep flashing
2) Give a beep sound for every 10 sec.
3) All DRO functions are disabled
Actual Dimension display
Shrinkage Compensated display
The displayed dimension are now multiply
by the
shrink factor ( 1.005 in this example )
Example : To compensate by Expand, so that the DRO's
actual displayed dimension are expanded
by the ratio of the
shrink factor .
