Diagnostic bits
The diagnostic bits store information about the status of a tool.
The bits are set either by programming in the NC program or
automatically by the tool and load monitoring functions.
The following diagnostic bits are available:
Tool life expired or max. quantity exceeded
1
Breakage detected via load monitoring (limit 2)
2
Wear ascertained via load monitoring (limit 1)
3
Wear according to load monitoring (total load)
4
Wear measured through tool calibration
5
Wear measured via in-process workpiece measurement
6
Wear measured via post-process workpc. measurement
7
Cutting edge is new
8
New = 1
Used = 0
9 – 15 Not assigned
If tool life monitoring or quantity monitoring is active and a
diagnostic bit has been set, the tool concerned will not be re-
inserted during Program run submode. If a replacement tool has
been defined, it will be inserted instead. If no replacement tool
has been defined or if the end of the tool sequence of exchange is
reached, the NC program is stopped before the next tool call.
Editing the diagnostic bits
You can edit the diagnostic bits in Tool editor mode of operation
as follows:
Press the Edit soft key
Press the Diagnosis Bits soft key
Use the cursor keys to select the desired bit
Press the GOTO key to edit the bit
Save the bit with the Confirm changes soft key
The control copies the new diagnostic bits to the
DG parameter. The data on tool life and quantity
limit remain unaffected.
Resetting the diagnostic bits
You can reset the diagnostic bits in the Tool editor mode of
operation as follows:
Press the Edit soft key
Press the New tooth soft key
With the New tooth soft key, you reset the diagnostic
bits and set bit 8 Cutting edge is new. This bit will also
be reset as soon as the control inserts the tool.
