7.2.6.7 Stock removal estimate memory
This memory can be used to estimate the stock metal removal when the probes are not in contact with the
part. For examples, in the case of a “reciprocating" type internal grinder: The measurement head enters and
exits the part alternatively during the machining process.
The memory blocks the measurement when the probes are outside the part. The block can be activated via
the I/O input or automatically if the measurement value < -60µm.
Settings
With P3UP in manual
mode, check that the CONTACT ON message
appears on the alphanumerical display when the probes are positioned in
the part (e.g. for ID applications).
If the block measurement signal is not available on the I/O, set-
measurement acquisition time. Sele
ct the acquisition time so that the
measurement is stable at the part working speed. Carry out the same check
when the memory is blocked from the I/O input.
The memory is active if the DYN LED is on.
It is possible to disable the memory with P3UP in manual mode passing to
static mode (DYN LED off). Alternatively, it is also possible to disable the
memory in automatic mode.
MEMORY CONTROL
If the memory is locked by the I/O synchronisation, there are two possible
types of function:
a.
Cycle without processing: the MEMORY CONTROL input has the
following function: ON = the memory samples the measurement,
OFF = the measurement is frozen at the last acquired value; also, if
the "estimate removal" function is active (factory setting) during the
OFF phase the memory allows the measurement value to drop
automatically according to the previously calculated removal
estimate;
b. Cycle with MAX/MIN/MEAN processing: in this case the
MEMORY CONTROL input is used to synchronise Max./Min/Mean
processing; these processes stop when the intervals set-
corresponding menu item expire. If the "estimate removal" function is
active (factory setting) during the OFF phase the memory allows the
measurement value to drop automatically according to the previously
calculated removal estimate.
When the contact drops into the interruption, the gauge indicator needle
remains stationary, thanks to the synchronisation (generated internally or
externally via MEMORY CONTROL).
1. Cycle without processing: the POWER LED, which is normally GREEN,
turns BLUE when the memory is frozen.
2. Cycle with Max/Min/Mean processing: if the DYN LED on the panel is
off the POWER LED is GREEN. If the DYN LED is on, the POWER LED
is normally BLUE, apart from the instants when the measurement is
updated when it turns GREEN.
