During the daily machining process, it is very common that the machining cannot
be completed within one working shift, and hence the DRO has to be switched
off, or less commonly,  a power failure occurs whilst machining which leads to
loss of the work piece datum ( work piece zero position ). The re-establishment
of work piece datum using edge finder or other method inevitably introduces
machining inaccuracies, because it is not possible to re-establish the work piece
datum exactly at the previous position.

To allow the recovery of work piece datum very accurately, with no need to
re-establish the work piece datum using an edge finder or other methods, every
transducer has a reference point location to provide a datum point memory function.

The working principal of the ref datum memory function is as follows.

-

There are a permanent and fixed mark (position) on the transducer,

normally called

mark or

point..

ref

ref

Since this

point position is permanent and fixed, it will never change or

ref

disappear when the DRO system is switched off. Therefore, we simply need to
store the distance between  the

point and the work piece datum ( zero

ref

position ) in DRO's memory.  Then, in case of the power  failure or the RD-14G being
switched off, we can recover the work piece datum ( zero position ) by presetting
the display zero position as the stored distance from the

point.
